Spring Boot 核心机制与实战：从自动装配到 MySQL、Redis、Security 集成在 Java Web 开发领域，Spring Boot 通过其核心机制——自动装配（Auto-Configuration）和 Starter 依赖，极大地简化了企业级应用的构建与部署流程。自动装配的原理在于，框架根据项目引入的依赖和现有配置，智能地装配所需的 Spring Bean，实现了“约定大于配置”的理念。这一机制的技术价值在于，它将开发者从繁琐的 XML 配置和依赖管理中解放出来，显著提升了开发效率，并确保了应用的生产就绪性。其应用场景广泛覆盖了 Web 服务、数据访问、缓存和安全认证等现代应用的核阅读详情

最近花了有三个星期把spring实战学了遍，同时也把maven,git，Hibernate给用上了，确实比较锻炼手。登陆，注册（我前端不是很好）是网上找得模版,（提前说下界面做的很挫，是用来练手的，还有很多写的不是很好的代码，我会慢慢完善的，但功能是全的）

          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

第二步配置视图解析器

@Configuration
@EnableRedisRepositories("Repository")
public class ViewConfiguration {
    @Bean
    public ViewResolver viewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/pages/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(org.springframework.web.servlet.view.JstlView.class);
        return resolver;
    }


}

第三步配置spring安全

package Configuration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import service.UserLoginService;

import javax.sql.DataSource;

/**
 * Created by wang on 16/12/5.
 */
@Configuration
@EnableWebSecurity
@ComponentScan(basePackageClasses = {UserLoginService.class,EntitymanagerFactoryBeanConfiguration.class})
public class SecurityConfiguration extends WebSecurityConfigurerAdapter{
    @Autowired
    DataSource dataSource;

    @Autowired
    private UserLoginService userLoginService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
       http.authorizeRequests().regexMatchers("/login/\\S+").access("hasRole('ROLE_USER') or IS_AUTHENTICATED_REMEMBERED")
               .regexMatchers("register/\\S+").access("hasRole('ROLE_USER') or IS_AUTHENTICATED_REMEMBERED")
       .and().formLogin().loginPage("/login").usernameParameter("username").passwordParameter("password").defaultSuccessUrl("/login/success")
       .and().logout().logoutSuccessUrl("/login");


    }


    @Autowired
    public void  configureGlobalSecurity(AuthenticationManagerBuilder auth)throws Exception{
        System.out.println("cG");
        /*这个Service会在后面重写*/
       auth.userDetailsService(userLoginService);

    }


}

package Configuration;

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;

/**
 * Created by wang on 16/12/5.
 */
public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer{


}

第五步继续配置安全，不过是同过继承UserDetails来封装user的信息，这段代码可以在看完user之后再看

package service;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.Collection;
import java.util.List;

/**
 * Created by wang on 16/12/7.
 */
public class UserRealDetails implements UserDetails{
    private List<GrantedAuthority> authorityList;
    private String Password;
    private String Username;
    private boolean isAccountNonExpired;
    private boolean isAccountNonLocked;
    private boolean isCredentialsNonExpired;
    private String email;
    private String firstName;
    private String lastName;
    private String phoneNumber;
    private int remaingMoney;
    private boolean enalbel;
    private long id;

    public UserRealDetails(List<GrantedAuthority> authorityList, boolean enalbel,String password, String username, boolean isAccountNonExpired, boolean isAccountNonLocked, boolean isCredentialsNonExpired, String email, String firstName, String lastName, String phoneNumber,int remaingMoney,long id) {
        this.authorityList = authorityList;
        Password = password;
        Username = username;
        this.isAccountNonExpired = isAccountNonExpired;
        this.isAccountNonLocked = isAccountNonLocked;
        this.isCredentialsNonExpired = isCredentialsNonExpired;
        this.email = email;
        this.firstName = firstName;
        this.lastName = lastName;
        this.phoneNumber = phoneNumber;
        this.enalbel =enalbel;
        this.remaingMoney = remaingMoney;
        this.id=id;
    }

    public long getId() {
        return id;
    }

    public int getRemaingMoney() {
        return remaingMoney;
    }

    public String getEmail() {
        return email;
    }

    public String getFirstName() {
        return firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public String getPhoneNumber() {
        return phoneNumber;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return authorityList;
    }

    @Override
    public String getPassword() {
        return Password;
    }

    @Override
    public String getUsername() {
        return Username;
    }

    @Override
    public boolean isAccountNonExpired() {
        return isAccountNonExpired;
    }

    @Override
    public boolean isAccountNonLocked() {
        return isAccountNonLocked;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return isCredentialsNonExpired;
    }

    @Override
    public boolean isEnabled() {
        return enalbel;
    }


}

这是之前提到的serviece,这是自定义的验证的服务

package service;

import Dao.UserDao;
import Domin.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by wang on 16/12/6.
 */
@Service
@EnableAspectJAutoProxy(proxyTargetClass = true)
@ComponentScan({"Dao","Configuration"})
public class UserLoginService implements UserDetailsService{
    @Autowired
    private UserDao userDao;


    @Cacheable("User")
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userDao.findByUserName(username);
        System.out.println("User"+user);
        if (user==null){
            System.out.println("User not found");
            throw new UsernameNotFoundException("UserName not found");
        }


       return new UserRealDetails(getGrantedAuthorities(user),user.getEnable().equals("true"),user.getPassWord(),user.getUserName(),
                true,true,true,user.getEmail(),user.getFirstName(),
                user.getLastName(),user.getPhoneNumber(),user.getRemainingMoney(),user.getId());
    }
    private List<GrantedAuthority> getGrantedAuthorities(User user){
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        authorities.add(new SimpleGrantedAuthority(user.getAuthorityTable().getUserAuth()));
        return authorities;
    }
}

第六步用来，建立表单，这里可以学一对一，一对多，多对多的例子（楼主表单名字没起好，学生成绩的表单和专门放科目的表单名字不易区分，后期维护肯定难）

@Entity
@Table(name = "user")
public class User implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @NotNull
    @Column(name = "userName", nullable = true, unique = true, length = 30)
    private String userName;

    @NotNull
    @Column(name = "passWord", nullable = true, length = 30)
    private String passWord;
    @Column
    private int RemainingMoney;

    @NotNull

    @Column(name = "phoneNumber", nullable = true, length = 20)
    private String phoneNumber;
    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name = "studentId")
    private List<Studentscore> scoreTable;

    @NotNull
    @Column(name = "email", nullable = true, unique = true, length = 50)
    private String email;
    @NotNull
    @Column(name = "lastName", nullable = true, length = 20)
    private String lastName;
    @NotNull
    @Column(name = "firstName", nullable = true, length = 20)
    private String firstName;

    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    @JoinTable(name = "User_Table", joinColumns = {@JoinColumn(name = "id")},
            inverseJoinColumns = {@JoinColumn(name = "TABLE_ID")})
    private List<scoreTable> table;

    @Column(name = "enable")
    private String enable;

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "authId")
    private AuthorityTable authorityTable;

    public AuthorityTable getAuthorityTable() {
        return authorityTable;
    }

    public void setAuthorityTable(AuthorityTable authorityTable) {
        this.authorityTable = authorityTable;
    }

    public List<Studentscore> getScoreTable() {
        return scoreTable;
    }

    public void setScoreTable(List<Studentscore> scoreTable) {
        this.scoreTable = scoreTable;
    }

    @Override
    public int hashCode() {
        return new HashCodeBuilder(17, 37).append(id).toHashCode();
    }

    public String getEnable() {
        return enable;
    }

    public void setEnable(String enable) {
        this.enable = enable;
    }

    @Override
    public boolean equals(Object obj) {
        if (obj == null) {
            return false;
        }
        if (obj == this) {
            return true;
        }
        if (obj.getClass() != getClass()) {
            return false;
        }
        User user = (User) obj;
        return new EqualsBuilder().appendSuper(super.equals(obj))
                .append(id, user.id).isEquals();
    }

    public int getRemainingMoney() {
        return RemainingMoney;
    }

    public void setRemainingMoney(int remainingMoney) {
        RemainingMoney = remainingMoney;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getLastName() {

    public void setPassWord(String passWord) {

    public String getEmail() {
        return email;

    public List<scoreTable> getTable() {
        return table;
    }

    public void setTable(List<scoreTable> table) {
        this.table = table;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

@Entity
@Table(name = "student_score")
public class Studentscore {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    private String courseName;

    private String score;


    public String getCourseName() {
        return courseName;
    }

    public void setCourseName(String courseName) {
        this.courseName = courseName;
    }

    public int getId() {

    public void setScore(String score) {

}

package Domin;

import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;

import javax.persistence.*;
import java.io.Serializable;
import java.util.List;

/**
 * Created by wang on 16/12/2.
 */
@Entity
@Table(name = "score")
public class scoreTable implements Serializable{
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "TABLE_ID")
    private int id;

    @ManyToMany(mappedBy = "table",fetch = FetchType.EAGER)
    private List<User> list;

    private String courseName;

    private int price;


    public List<User> getList() {
        return list;

        if (obj == this){return true;}
        if (obj.getClass()!=getClass()){
            return false;
        }
        scoreTable table = (scoreTable) obj;
        return new EqualsBuilder()
                .append(id,table.getId()).isEquals();
    }
}

package Domin;

import javax.persistence.*;

/**
 * Created by wang on 16/12/5.
 */
@Entity
@Table(name = "auth")
public class AuthorityTable {
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Id
    private int id;
   @OneToOne(mappedBy = "authorityTable")
    private User user;
   @Column
    private String userAuth;

    public long getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    public String getUserAuth() {
        return userAuth;
    }

    public void setUserAuth(String userAuth) {
        this.userAuth = userAuth;
    }
}

第七步，建立dao层（没有service层，多了一层Repository层），这里会用到spring data jpa

public interface UserRepository extends JpaRepository<User,Integer> {
    //User findByuserName(String username);

    User saveAndFlush(User entity);
    List<User> findByFirstName(String firstName);
    User findByUserName(String userName);
    User findByEmail(String email);
    List<User> findByLastName(String lastName);
    User findById(long id);
//    List<scoreTable> findTable(long id);

    @Query("select t.scoreTable from  Domin.User t where t.id =?1")
    List<Studentscore> getByScoreTable(long id);

    @Modifying
    @Query(value = "update Domin.User t set t.firstName = ?1 where t.id = ?2")
    void updateFirstName(String newFirstName,long id);
    @Modifying
    @Query(value = "update Domin.User t set t.lastName= ?1 where t.id=?2")
    void updateLastName(String newLastname,long id);
    @Modifying
    @Query(value = "update Domin.User t set t.passWord=?1 where t.id = ?2")
    void updatePassWord(String newPassWord,long id);
    @Query("select t.table from Domin.User t  where t.id=?1 ")
    List<scoreTable> findscoreTable(long id);
    @Modifying
    @Query(value = "update Domin.User t set  t.table = ?1 where t.id = ?2")
    void updateScoreTable(List<scoreTable> newList, long id);
    @Modifying
    @Query(value = "update Domin.User as t set t.RemainingMoney = ?1 where t.id = ?2")
    void updateRemainningMoney(int newMoney,long id);

}

有些数据库的改动，jpa我实在想不到怎么改了，都是异常。最后只能先妥协用这种方法

@Repository
@ComponentScan(basePackageClasses = EntitymanagerFactoryBeanConfiguration.class)
@Transactional
public class UserDao {
   @Autowired
    private UserRepository userRepository;

   @Autowired
   private CourseDao courseDao;
   @PersistenceContext
    private EntityManager entityManager;

    public User findByid(long id){
        return  userRepository.findById(id);
    }
    @Transactional
    public User save(User user){
        return userRepository.save(user);
    }
    @Transactional
    public User findByUserName(String userName){
        return userRepository.findByUserName(userName);
    }
    @Transactional
    public List<User> fingbyFirstName(String firstName){
        return userRepository.findByFirstName(firstName);
    }
    @Transactional
    public List<User> findbyLastName(String lastName){
        return userRepository.findByLastName(lastName);
    }
    @Transactional
    public User findbyEmail(String email){
        return userRepository.findByEmail(email);
    }
    @Transactional
    public void updataFirstName(String newFirstName,int id){
        userRepository.updateFirstName(newFirstName,id);
    }
    @Transactional
    public void updateLastName(String newLastName,int id){
        userRepository.updateLastName(newLastName,id);
    }
    @Transactional
    public void updatePassWord(String newpassWord , int id){
        userRepository.updatePassWord(newpassWord,id);
    }
    @Transactional
    public List<scoreTable> findScoreTableById(long id){
        return userRepository.findscoreTable(id);
    }

    @Transactional
    public List<Studentscore> findStudentScoreTable(long id){
        return userRepository.getByScoreTable(id);
    }
    @Transactional
    public void updateAllTable (List<scoreTable> newTable , long id){
        User user = userRepository.findById(id);
        user.getTable().add(courseDao.findCourseName("MATH"));
        user.setTable(newTable);
        entityManager.flush();
       userRepository.updateScoreTable(newTable,id);
    }
    @Transactional
    public  void addStudentScoreTable(Studentscore table,long id){
        User user = userRepository.findById(id);
        if(user.getScoreTable()!=null){
            user.getScoreTable().add(table);
        }else {
            List<Studentscore> list = new ArrayList<>();
            list.add(table);
            user.setScoreTable(list);
        }
        entityManager.persist(user);
    }
    @Transactional
    public void addscoreTable (scoreTable table,long id){
        User user=userRepository.findById(id);
        if(user.getTable()!=null){
            user.getTable().add(table);
        }else {
            List<scoreTable> list = new ArrayList<>();
            list.add(table);
            user.setTable(list);
        }
        entityManager.merge(user);
    }
    public void deleteScoreTable(scoreTable table,long id){
        User user = userRepository.findById(id);
        if(!user.getTable().remove(table)){
            throw new NoSuchElementException("没有这张成绩单");
        }

    }
    @Transactional
    public void updataRemainningMoney (int newMoney,long id){
        this.userRepository.updateRemainningMoney(newMoney,id);
    }
}

package Dao;

import Domin.scoreTable;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Repository;
import Repository.ScoreTableRepository;
/**
 * Created by wang on 16/12/10.
 */
@Repository
@ComponentScan("Respository")
public class CourseDao {
    @Autowired
    private ScoreTableRepository scoreTableRepository;
    public scoreTable findCourseName(String courseName){
        return scoreTableRepository.findByCourseName(courseName);
    }

}

第八步，建立控制器，登陆进去靠security,是不需要自己写控制器的

package Controller;

import Dao.CourseDao;
import Dao.UserDao;
import Domin.Studentscore;
import Domin.User;
import Domin.scoreTable;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.SessionAttribute;
import service.UserRealDetails;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

/**
 * Created by wang on 16/12/10.
 */
@Controller
@RequestMapping("/buy/")
@ComponentScan("Dao")
public class BuyController {
    @Autowired
    private HttpSession session;
    @Autowired
    private CourseDao courseDao;
    @Autowired
    private UserDao userDao;
    @RequestMapping("course")
    public String buyCourese(@RequestParam("name") String courseName, Model model, HttpServletRequest request){
        scoreTable scoreTable = courseDao.findCourseName(courseName);
        System.out.println(scoreTable);
        model.addAttribute("scoreTable",scoreTable);
        request.getSession().setAttribute("scoreTable",scoreTable);
        System.out.println(11);
        return "pay";
    }
    @RequestMapping("success")
    public String buyEnd(@SessionAttribute UserRealDetails user, @SessionAttribute scoreTable scoreTable,Model model,HttpServletRequest request){
        int remainMoney = user.getRemaingMoney()-scoreTable.getPrice();
        User realUser = userDao.findByUserName(user.getUsername());

        if (realUser.getTable()==null||realUser.getTable().contains(scoreTable)){
            System.out.println(0);
            model.addAttribute("message","考试已经报名");
            return "pay";
        }

       if (remainMoney>0) {
            request.removeAttribute("message");
           userDao.updataRemainningMoney(remainMoney,realUser.getId());

           userDao.addscoreTable(scoreTable,realUser.getId());
           realUser.setRemainingMoney(remainMoney);

           Studentscore studentscore = new Studentscore();
           studentscore.setCourseName(scoreTable.getCourseName());
           studentscore.setScore("noScore");

           userDao.addStudentScoreTable(studentscore,realUser.getId());
           if (model.containsAttribute("user1")){
               model.asMap().put("user1",realUser);
           }else {
               model.addAttribute("user1", realUser);
           }
           return "profile";
       }
            return "makemoney";
    }
}

这是如果购买没钱，就会进入充钱的网站

package Controller;

import Dao.UserDao;
import Domin.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.SessionAttribute;
import service.UserRealDetails;

import javax.servlet.http.HttpServletRequest;
import javax.transaction.Transactional;

/**
 * Created by wang on 16/12/14.
 */
@Controller
@RequestMapping("/")
public class MakeMoney {
    @Autowired
    private UserDao userDao;
    @RequestMapping("makemoney.do")
    @Transactional
    public String  makeMoney(String money, @SessionAttribute UserRealDetails user, HttpServletRequest request){
        User user1 = userDao.findByid(user.getId());
        int nowMoney = user1.getRemainingMoney()+Integer.valueOf(money);
        System.out.println(55);
        if (request.getSession().getAttribute("user1")!=null){
            user1.setRemainingMoney(nowMoney);
            request.getSession().setAttribute("user1",user1);
            userDao.updataRemainningMoney(nowMoney,user.getId());

            return"profile";
        }else {

            user1.setRemainingMoney(nowMoney);
            request.getSession().setAttribute("user1",user1);
            userDao.updataRemainningMoney(nowMoney,user.getId());
            return "profile";
        }
    }
}

最后是视图（模版随意用）

这是登陆页面
