我做这个只是为了方便自己开发时候直接过来复制！！！！！！配置的东西太多了，一个一个搞太麻烦，这些东西谁写都大同小异！用到粘贴根据自己项目实际情况修改即可！！！！

数据库配置文件：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmtest
jdbc.username=root
jdbc.password=root

常用maven坐标体系：

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
  </properties>

纯注解开发配置类：

jdbc配置：

import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;

import javax.sql.DataSource;

public class JdbcConfig {
    //使用注入的形式，读取properties文件中的属性值，等同于<property name="*******" value="${jdbc.driver}"/>
    @Value("${jdbc.driver}")
    private String driver;
    @Value("${jdbc.url}")
    private String url;
    @Value("${jdbc.username}")
    private String userName;
    @Value("${jdbc.password}")
    private String password;

    //定义dataSource的bean，等同于<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
    @Bean("dataSource")
    public DataSource getDataSource(){
        //创建对象
        DruidDataSource ds = new DruidDataSource();
        //手工调用set方法，等同于set属性注入<property name="driverClassName" value="******"/>
        ds.setDriverClassName(driver);
        ds.setUrl(url);
        ds.setUsername(userName);
        ds.setPassword(password);
        return ds;
    }
}

mybatis配置：


import com.github.pagehelper.PageInterceptor;
import org.apache.ibatis.plugin.Interceptor;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;

import javax.sql.DataSource;
import java.util.Properties;

public class MyBatisConfig {
    //定义MyBatis的核心连接工厂bean，等同于<bean class="org.mybatis.spring.SqlSessionFactoryBean">
    @Bean
    //参数使用自动装配的形式加载dataSource，为set注入提供数据，dataSource来源于JdbcConfig中的配置
    public SqlSessionFactoryBean getSqlSessionFactoryBean(@Autowired DataSource dataSource,@Autowired Interceptor interceptor){
        SqlSessionFactoryBean ssfb = new SqlSessionFactoryBean();
        //等同于<property name="typeAliasesPackage" value="com.domain"/>
        ssfb.setTypeAliasesPackage("com.domain");
        //等同于<property name="dataSource" ref="dataSource"/>
        ssfb.setDataSource(dataSource);
//        //等同于<bean class="com.github.pagehelper.PageInterceptor">
//        Interceptor interceptor = new PageInterceptor();
//        Properties properties = new Properties();
//        properties.setProperty("helperDialect","mysql");
//        properties.setProperty("reasonable","true");
//        //等同于<property name="properties">
//        interceptor.setProperties(properties);
        ssfb.setPlugins(interceptor);
        return ssfb;
    }

    //定义MyBatis的映射扫描，等同于<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    @Bean
    public MapperScannerConfigurer getMapperScannerConfigurer(){
        MapperScannerConfigurer msc = new MapperScannerConfigurer();
        //等同于<property name="basePackage" value="com.dao"/>
        msc.setBasePackage("com.dao");
        return msc;
    }

    /**
     * 分页插件的配置.必须这样命名
     * @return
     */
    @Bean("pageInterceptor")
    public Interceptor getPageInterceptor(){
        Interceptor interceptor = new PageInterceptor();
        Properties properties = new Properties();
        properties.setProperty("helperDialect","mysql");
        properties.setProperty("reasonable","true");
        //等同于<property name="properties">
        interceptor.setProperties(properties);
        return interceptor;
    }

}

web.xml替换成集成AbstractDispatcherServletInitializer的类！

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.support.AbstractDispatcherServletInitializer;

import javax.servlet.DispatcherType;
import javax.servlet.FilterRegistration;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import java.util.EnumSet;

public class ServletContainersInitConfig extends AbstractDispatcherServletInitializer {

    //创建Servlet容器时，使用注解的方式加载SPRINGMVC配置类中的信息，并加载成WEB专用的ApplicationContext对象
    //该对象放入了ServletContext范围，后期在整个WEB容器中可以随时获取调用
    @Override
    protected WebApplicationContext createServletApplicationContext() {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(SpringMvcConfig.class);
        return ctx;
    }

    //注解配置映射地址方式，服务于SpringMVC的核心控制器DispatcherServlet
    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }

    @Override
    //基本等同于<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    protected WebApplicationContext createRootApplicationContext() {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(SpringConfig.class);
        return ctx;
    }

    //乱码处理作为过滤器，在servlet容器启动时进行配置，相关内容参看Servlet零配置相关课程
    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        //触发父类的onStartup
        super.onStartup(servletContext);
        //1.创建字符集过滤器对象
        CharacterEncodingFilter cef = new CharacterEncodingFilter();
        //2.设置使用的字符集
        cef.setEncoding("UTF-8");
        //3.添加到容器（它不是ioc容器，而是ServletContainer）
        FilterRegistration.Dynamic registration = servletContext.addFilter("characterEncodingFilter", cef);
        //4.添加映射
        registration.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST, DispatcherType.FORWARD, DispatcherType.INCLUDE), false, "/*");
    }
}

Spring核心配置类：


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.*;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.sql.DataSource;

@Configuration
//等同于<context:component-scan base-package="com">
@ComponentScan(value = "com.itheima",excludeFilters =
    //等同于<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    @ComponentScan.Filter(type= FilterType.ANNOTATION,classes = {Controller.class}))
//等同于<context:property-placeholder location="classpath*:jdbc.properties"/>
@PropertySource("classpath:jdbc.properties")
//等同于<tx:annotation-driven />，bean的名称默认取transactionManager
@EnableTransactionManagement
@Import({MyBatisConfig.class,JdbcConfig.class})
public class SpringConfig {
    //等同于<bean id="txManager"/>
    @Bean("transactionManager")
    //等同于<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    public DataSourceTransactionManager getTxManager(@Autowired DataSource dataSource){
        DataSourceTransactionManager tm = new DataSourceTransactionManager();
        //等同于<property name="dataSource" ref="dataSource"/>
        tm.setDataSource(dataSource);
        return tm;
    }
}

SpringMVC核心配置类：


import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
//等同于<context:component-scan base-package="com.controller"/>
@ComponentScan("com.itheima.controller")
//等同于<mvc:annotation-driven/>，还不完全相同
@EnableWebMvc
public class SpringMvcConfig {
}

关于mybatis映射文件纯主机注解和xml

关于多表多类型的详细写法写法参考mybatis篇幅总结地址：Mybatis基本使用总括（单表/多表/动态sql）_楠~枫的博客-优快云博客：下面的示意简单写法！

注解版范例：


public interface UserDao {
    /**
     * 添加用户
     * @param user
     * @return
     */
    @Insert("insert into user(userName,password,realName,gender,birthday)values(#{userName},#{password},#{realName},#{gender},#{birthday})")
    public boolean save(User user);

    /**
     * 修改用户
     * @param user
     * @return
     */
    @Update("update user set userName=#{userName},password=#{password},realName=#{realName},gender=#{gender},birthday=#{birthday} where uuid=#{uuid}")
    public boolean update(User user);

    /**
     * 删除用户
     * @param uuid
     * @return
     */
    @Delete("delete from user where uuid = #{uuid}")
    public boolean delete(Integer uuid);

    /**
     * 查询单个用户信息
     * @param uuid
     * @return
     */
    @Select("select * from user where uuid = #{uuid}")
    public User get(Integer uuid);

    /**
     * 查询全部用户信息
     * @return
     */
    @Select("select * from user")
    public List<User> getAll();


    /**
     * 根据用户名密码查询个人信息
     * @param userName 用户名
     * @param password 密码信息
     * @return
     */
    @Select("select * from user where userName=#{userName} and password=#{password}")
    //注意：数据层操作不要和业务层操作的名称混淆，通常数据层仅反映与数据库间的信息交换，不体现业务逻辑
    public User getByUserNameAndPassword(@Param("userName") String userName,@Param("password") String password);
}

xml形式，注意xml文件必须和类同名，接口在java目录下，但是xml在resources目录下创建和java相同的目录层级：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dao.UserDao">

    <!--添加-->
    <insert id="save" parameterType="user">
        insert into user(userName,password,realName,gender,birthday)values(#{userName},#{password},#{realName},#{gender},#{birthday})
    </insert>

    <!--删除-->
    <delete id="delete" parameterType="int">
        delete from user where uuid = #{uuid}
    </delete>

    <!--修改-->
    <update id="update" parameterType="user">
        update user set userName=#{userName},password=#{password},realName=#{realName},gender=#{gender},birthday=#{birthday} where uuid=#{uuid}
    </update>

    <!--查询单个-->
    <select id="get" resultType="user" parameterType="int">
        select * from user where uuid = #{uuid}
    </select>

    <!--分页查询-->
    <select id="getAll" resultType="user">
        select * from user
    </select>

    <!--登录-->
    <select id="getByUserNameAndPassword" resultType="user" >
        select * from user where userName=#{userName} and password=#{password}
    </select>

</mapper>

接口：


public interface UserDao {
    /**
     * 添加用户
     * @param user
     * @return
     */
    public boolean save(User user);

    /**
     * 修改用户
     * @param user
     * @return
     */
    public boolean update(User user);

    /**
     * 删除用户
     * @param uuid
     * @return
     */
    public boolean delete(Integer uuid);

    /**
     * 查询单个用户信息
     * @param uuid
     * @return
     */
    public User get(Integer uuid);

    /**
     * 查询全部用户信息
     * @return
     */
    public List<User> getAll();


    /**
     * 根据用户名密码查询个人信息
     * @param userName 用户名
     * @param password 密码信息
     * @return
     */
    //注意：数据层操作不要和业务层操作的名称混淆，通常数据层仅反映与数据库间的信息交换，不体现业务逻辑
    public User getByUserNameAndPassword(@Param("userName") String userName,@Param("password") String password);
}

小范例：

配置文件信息上面已经做了，这里只做具体的代码实现，只有后端的：

控制层写法


@RequestMapping("/address")
@RestController
public class AddressController {
    /**
     * 自动装配会找到接口的实现类，这块就注入接口对象，不是注入实现类的对象，注入实现类对象显的lou
     */
    @Autowired
    private AddressService addressService;


    /**
     * 用请求方式区别即可
     * @param address
     * @return
     */
    @PostMapping
    public Result addAddresss(Address address) {
        if (addressService.add(address)) {
            return new Result(1, true, "成功");
        } else {
            return new Result(2, false, "失败");
        }
    }

    /**
     * 用请求方式区别即可
     * @param address
     * @return
     */
    @PutMapping
    public Result updateAddresss(Address address) {
        if (addressService.update(address)) {
            return new Result(1, true, "成功");
        } else {
            return new Result(2, false, "失败");
        }
    }

    /**
     * 根据请求方式进行区别
     * @param id
     * @return
     */
    @DeleteMapping("/{id}")
    public Result delateAddresss(@PathVariable int id) {
        if (addressService.delete(id)) {
            return new Result(1, true, "成功");
        } else {
            return new Result(2, false, "失败");
        }
    }

    /**
     * 根据请求方式进行区别
     * @param id
     * @return

result根据实际情况做javabean吧！一般含有提示信息，数据，成功与否，等属性！！！！

业务层：

业务层接口


//将事务添加到接口上实现类中免得再写
//对所有的方法开启事务为只读，但是方法若是存在其他的方式，在个别方法上进行修改即可，会有覆盖效果！
@Transactional(readOnly = true)

     * @param userName

业务层实现类：

@Service
public class AddressServiceImp implements AddressService {

    @Autowired
    private AddressDao addressDao;

    /**
     * 添加
     * @param address
     * @return

     * @return
     */
    @Override
    public boolean delete(int id) {
        return addressDao.delete(id);

    }

    /**
     * 修改
     *

    }

    /**

    @Override
    public Address getOne(int id) {
        return addressDao.getOne(id);
    }

    /**
     * 分页查询
     *
     * @param page
     * @param size
     * @return
     */
    @Override
    public PageInfo<Address> getAll(int page, int size) {
        PageHelper.startPage(page, size);
        List<Address> all = addressDao.getAll();
        return new PageInfo<Address>(all);
    }
}

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserDao userDao;

    @Override
    public boolean save(User user) {
        return userDao.save(user);
    }

    @Override
    public boolean update(User user) {
        return userDao.update(user);
    }

    @Override
    public boolean delete(Integer uuid) {
        return userDao.delete(uuid);
    }

    @Override
    public User get(Integer uuid) {
        return userDao.get(uuid);
    }

    @Override
    public PageInfo<User> getAll(int page,int size) {
        PageHelper.startPage(page,size);
        List<User> all = userDao.getAll();
        return new PageInfo<User>(all);
    }

    @Override
    public User login(String userName, String password) {
        return userDao.getByUserNameAndPassword(userName,password);
    }
}

持久层上面mybatis已经展示的。。。。。。。。。！

测试类！

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")


public class AddressServiceTest {

    @Autowired
    private AddressService addressService;
//todo
}

其他的用到那块的去SpringMVC和Spring总结里找！

基本上开发体系框架就这样了!!!!!!!!!!

其他的用到啥去找啥几乎ok!！！！！！！！！
