struts+spring+mybatis框架整合

一转眼，毕业已经四个月了，回忆大学的点点滴滴，不由的想起了之前毕设做的东西，当时的项目是采用struts2+spring+mybatis框架开发的一个管理系统，整个项目的框架是由一个学长帮我们搭建好的，当时对于我这个刚接触java的童鞋，那样的东西感觉还是很新鲜的。利用空余时间，自己也使用struts2+spring+mybatis框架写个实现增删改查功能的例子。

不扯那么多了，进入正题。

首先，导入相关的jar包(后面附源码)

其次，创建并编写配置文件

ApplicationContext.xml     

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="

       http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

	</bean>

	<bean id="transactionManager"

	</bean>

	<!-- dao -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

	</bean>

	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

	</bean>
	<bean id="userService" class="com.wporoad.app.serviceImpl.UserServiceImpl">

	</bean>
	<bean id="userAction" class="com.wporoad.app.web.UserAction">
		<property name="userService" ref="userService" />
	</bean>

</beans>

　　数据源和映射文件都在ApplicationContext.xml进行配置

web.xml

　struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">

			<result name="error">/WEB-INF/page/error.jsp</result>
		</action>
		
	</package>
</struts>

　接下来就是编写后台程序了

1.辅助类

package com.wporoad.app.entity;

import java.io.Serializable;

public class User implements Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	private String id;
	private String userName;
	private String password;
	private String email;

	public String getId() {
		return id;
	}

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

	public String getUserName() {
		return userName;
	}

	public void setUsername(String userName) {
		this.userName = userName;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getEmail() {
		return email;
	}

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

}

　　2. action类UserAction

package com.wporoad.app.web;

import java.util.List;
import java.util.UUID;

import javax.servlet.http.HttpServletRequest;

import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;
import com.wporoad.app.entity.User;
import com.wporoad.app.service.UserService;

public class UserAction extends ActionSupport {
	private static final long serialVersionUID = 1L;
	private static Logger logger = Logger.getLogger(UserAction.class);

	public UserService userService;

	public UserService getUserService() {
		return userService;
	}

	public void setUserService(UserService userService) {
		this.userService = userService;
	}

	private String id;

	public String getId() {
		return id;
	}

	private String userName;
	private String password;
	private String email;

	/**
	 * 添加用户信息
	 * 
	 * @return
	 */
	public String addUser() {
		User user = new User();
		try {
			String iid = UUID.randomUUID().toString();
			user.setId(iid);
			user.setUsername(userName);
			user.setPassword(password);
			user.setEmail(email);
			userService.addUser(user);
		} catch (Exception e) {
			logger.error("exception in add user", e);
			return ERROR;
		}
		return SUCCESS;
	}

	/**
	 * 从数据库中获得所有的用户信息
	 * 
	 * @return
	 */
	public String queryUsers() {
		try {
			List<User> userList = userService.queryUsers();
			HttpServletRequest request = ServletActionContext.getRequest();
			request.setAttribute("list", userList);
			return "list";
		} catch (Exception e) {
			logger.error("Exception in queryUsers", e);
			return ERROR;
		}
	}

	/**
	 * 删除用户信息
	 * 
	 * @return
	 */
	public String delUser() {
		try {
			userService.delUser(id);
			List<User> userList = userService.queryUsers();
			HttpServletRequest request = ServletActionContext.getRequest();
			request.setAttribute("list", userList);
		} catch (Exception e) {
			logger.error("Exception in delUser", e);
			return ERROR;
		}
		return "list";
	}

	public String detailUser() {
		try {
			List<User> userList = userService.detailUser(id);
			User user = userList.get(0);
			HttpServletRequest request = ServletActionContext.getRequest();
			request.setAttribute("user", user);
			return "detail";
		} catch (Exception e) {
			logger.error(e);
			return ERROR;
		}
	}

	public String update() {
		List<User> userList = userService.detailUser(id);
		User user = userList.get(0);
		HttpServletRequest request = ServletActionContext.getRequest();
		request.setAttribute("user", user);
		return "update";
	}

	public String updateUser() {
		try {
			User user = new User();
			user.setId(id);
			user.setUsername(userName);
			user.setPassword(password);
			user.setEmail(email);
			userService.updateUser(user);
			return SUCCESS;
		} catch (Exception e) {
			logger.error(e);
			return ERROR;
		}
	}

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

	public void setUserName(String userName) {
		this.userName = userName;
	}

	public void setPassword(String password) {
		this.password = password;
	}

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

}

　　3.service层，UserService接口和UserServiceImpl

 UserService.java

package com.wporoad.app.service;

import java.util.List;

import com.wporoad.app.entity.User;

public interface UserService {
	/**
	 * 添加用户
	 * 
	 * @param user
	 */
	public void addUser(User user);

	/**
	 * 列出所有的用户
	 * 
	 * @return
	 */
	public List<User> queryUsers();

	/**
	 * 删除用户
	 * 
	 * @param id
	 */
	public void delUser(String id);

	/**
	 * 详细信息
	 * 
	 * @param id
	 */
	public List<User> detailUser(String id);

	/**
	 * 修改信息
	 * 
	 * @param User
	 */
	public void updateUser(User User);
}

　　UserServiceImpl.java

package com.wporoad.app.serviceImpl;

import java.util.List;

import com.wporoad.app.dao.UserMapper;
import com.wporoad.app.entity.User;
import com.wporoad.app.service.UserService;

public class UserServiceImpl implements UserService {
	private UserMapper userMapper;

	public UserMapper getUserMapper() {
		return userMapper;
	}

	public void setUserMapper(UserMapper userMapper) {
		this.userMapper = userMapper;
	}

	/**
	 * 添加用户
	 */
	public void addUser(User user) {
		userMapper.addUser(user);
	}

	/**
	 * 列出所有用户
	 */
	public List<User> queryUsers() {
		List<User> userList = userMapper.queryUsers();
		return userList;
	}

	/**
	 * 删除用户
	 */
	public void delUser(String id) {
		userMapper.delUser(id);
	}

	public List<User> detailUser(String id) {
		return userMapper.detailUser(id);
	}

	@Override
	public void updateUser(User User) {
		userMapper.updateUser(User);
	}

}

　　4. Dao层UserMapper.java和映射文件UserMaper.xml

UserMapper.java

package com.wporoad.app.dao;

import java.util.List;

import com.wporoad.app.entity.User;

public interface UserMapper {
	/**
	 * 添加用户
	 * @param user
	 */
	public void addUser(User user);
	
	/**
	 * 列出所有用户
	 * @return
	 */
	public List<User> queryUsers();
	
	/**
	 * 删除用户
	 * @param id
	 */
	public void delUser(String id);
	
	/**
	 * 详细信息
	 * @param id
	 */
	public List<User> detailUser(String id);
	
	/**
	 * 修改信息
	 * @param User
	 */
	public void updateUser(User User);
}

　　UserMapper.xml

<?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.wporoad.app.dao.UserMapper">

	<resultMap id="UserMap" type="com.wporoad.app.entity.User">
		<result property="id" column="ID" />
		<result property="userName" column="USERNAME" />
		<result property="password" column="PASSWORD" />
		<result property="email" column="EMAIL" />
	</resultMap>

	<insert id="addUser" parameterType="User">
		INSERT INTO USER(
		ID,
		USERNAME,
		PASSWORD,
		EMAIL
		)
		VALUES (
		#{id},
		#{userName},
		#{password},
		#{email}
		)
	</insert>
	
	<select id="queryUsers" resultMap="UserMap" >
		SELECT * FROM USER
	</select>
	
	<!-- 删除信息 -->
	<delete id="delUser" parameterType="string">
		DELETE FROM USER WHERE ID = #{id}
	</delete>
	
	<select id="detailUser" parameterType="String" resultMap="UserMap">
		SELECT USERNAME,PASSWORD,EMAIL, ID
		FROM USER WHERE ID = #{value}
	</select>
	
	
	<!-- 更新信息 -->
	<update id="updateUser" parameterType="User">
		UPDATE USER
		<set>
			<if test="userName != null ">USERNAME = #{userName},</if>
			<if test="password != null ">PASSWORD = #{password},</if>
			<if test="email != null ">EMAIL = #{email}</if>
		</set>
		WHERE ID = #{id}
	</update>
	
	
</mapper>
