一、搭建开发环境

1、创建web项目，引入jar包

2、引入配置文件

Struts的框架:web.xml、struts.xml
- web.xml

<!-- 配置Struts的核心过滤器 -->
  <filter>
    <filter-name>Struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>Struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

Spring的框架
- jdbc.properties
- log4j.properties
- applicationContext.xml
- web.xml

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

Hibernate的框架
- hibernate.cfg.xml

3、创建相关包结构

Java Resources
- src
  - com.ithou.crm
    - dao
    - domain
    - service
  - web
    - action
    - interceptor

4、引入相关页面

5、创建与用户相关的类

UserDao、UserDaoImpl、User、UserService、UserServiceImpl、UserAction

6、将相关的类配置到Spring中

	<!-- 配置用户管理相关的类 -->
	<!-- 配置Dao -->
	<bean id="userDao" class="com.ithou.crm.dao.impl.UserDaoImpl">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
	<!-- 配置Service -->
	<bean id="userService" class="com.ithou.crm.service.impl.UserServiceImpl">
	</bean>
	<!-- 配置Action -->
	<bean id="UserAction" class="com.ithou.crm.web.action.UserAction" scope="prototype">
	</bean>

功能一：用户模块---用户注册代码实现

1、在登陆页面login.jsp提供一个注册页面

2、创建用户表

CREATE TABLE `sys_user` (
  `user_id` bigint(32) NOT NULL AUTO_INCREMENT COMMENT '用户id',
  `user_code` varchar(32) NOT NULL COMMENT '用户账号',
  `user_name` varchar(64) NOT NULL COMMENT '用户名称',
  `user_password` varchar(32) NOT NULL COMMENT '用户密码',
  `user_state` char(1) NOT NULL COMMENT '1:正常,0:暂停',
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

3、创建实体和映射

public class User {
	
	private Long user_id;
	private String user_code;
	private String user_name;
	private String user_password;
	private String user_state;
        
        get/set...
}

user.hbm.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
    
    <hibernate-mapping>
    	<class name="com.ithou.crm.domain.User" table="sys_user">
    		<id name="user_id" column="user_id">
    			<generator class="native"/>
    		</id>
    		<property name="user_code" column="user_code"/>
    		<property name="user_name" column="user_name"/>
    		<property name="user_password" column="user_password"/>
    		<property name="user_state" column="user_state"/>
    	</class>
    </hibernate-mapping>

4、编写Action

public class UserAction extends ActionSupport implements ModelDriven<User> {

	private User user = new User();
	
	@Override
	public User getModel() {
		return user;
	}
	
	private UserService userService;

	public void setUserService(UserService userService) {
		this.userService = userService;
	}
	
	public String regist() {
		System.out.println("用户注册的方法实现了......");
		userService.regist(user);
		return LOGIN;
	}
}

在Action中注入service：

	<!-- 配置Action -->
	<bean id="UserAction" class="com.ithou.crm.web.action.UserAction" scope="prototype">
		<property name="userService" ref="userService" />
	</bean>

配置Action的访问

		<action name="user_*" class="com.ithou.crm.web.action.UserAction" method="{1}">
			<result name="login">/login.jsp</result>
		</action>

5、编写service

public class UserServiceImpl implements UserService {

	private UserDao userDao;

	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}
	
	@Override
	public void regist(User user) {
                //对密码进行加密处理
		user.setUser_password(MD5Utils.md5(user.getUser_password()));
		user.setUser_state("1");
                //调用Dao
		userDao.regist(user);
	}
}

在service中注入dao：

	<bean id="userService" class="com.ithou.crm.service.impl.UserServiceImpl">
		<property name="userDao" ref="userDao" />
	</bean>

6、编写Dao

整合Hibernate

	<!-- 配置SessionFactory -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
		<!-- 注入连接池 -->
		<property name="dataSource" ref="dataSource" />
		<!-- 配置Hibernate的相关属性 -->
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.format_sql">true</prop>
				<prop key="hibernate.hbm2ddl.auto">update</prop>
			</props>
		</property>

		<!-- 引入映射文件 -->
		<property name="mappingResources">
			<list>
				<value>/com/ithou/crm/domain/user.hbm.xml</value>
			</list>
		</property>
	</bean>

在Dao中继承HibernateDaoSurrport类

public class UserDaoImpl extends BaseDaoImpl<User> implements UserDao {

	@Override
	/**
	 * 保存用户
	 */
	public void regist(User user) {
		this.getHibernateTemplate().save(user);
	}
}

在Dao中注入SessionFactory

	<bean id="userDao" class="com.ithou.crm.dao.impl.UserDaoImpl">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

7、配置Spring的事务管理

配置事务管理器

	<!-- 配置事务管理器 -->
	<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

开启注解事务

	<!-- 开启注解事务 -->
	<tx:annotation-driven transaction-manager="transactionManager" />

在业务层添加事务注解

功能二：用户模块---用户登录代码实现

1、修改登陆页面

2、编写Action中login方法

	public String login() {
		User existUser = userService.login(user);
		if(existUser == null) {
			this.addActionError("用户名或密码错误！");
			return LOGIN;
		}else {
			ActionContext.getContext().getSession().put("existUser",existUser);
			return SUCCESS;
		}
	}

3、编写Service

	@Override
	public User login(User user) {
		user.setUser_password(MD5Utils.md5(user.getUser_password()));
		return userDao.login(user);
	}

4、编写Dao

	@Override
	public User login(User user) {
		List<User> list = (List<User>) this.getHibernateTemplate().find(
				"from User where user_code = ? and user_password = ?", user.getUser_code(),user.getUser_password());
		if(list.size() > 0) {
			return list.get(0);
		}
		return null;
	}

5、配置页面的跳转

		<action name="user_*" class="com.ithou.crm.web.action.UserAction" method="{1}">
			<result name="login">/login.jsp</result>
			<result name="success" type="redirect">/index.jsp</result>
		</action>

6、在页面中显示数据

在成功页面显示用户信息
- top.jsp:

当前用户：<s:property value="#session.existUser.user_name"/>

在失败页面上显示信息
- login.jsp

<s:actionerror/>
