maven+spring+springmvc+mybatis调整

maven+spring+springmvc+mybatis整合

开发环境：eclipse-mars2（自带maven）

1，创建工程file-new-maven project-next

选择webapp-next

填写项目名字-finish

此时的项目前有红色X，项目结构也有问题，需要处理一下，选中项目右键-properties-resource-utf-8 apply

,选择java build path-jre-edit-勾选workspace defult……，apply-finish

还报错，继续，打开pom.xml，加入

!-- 导入java ee jar 包 -->
        <dependency>
            <groupId>javax</groupId>
            <artifactId>javaee-api</artifactId>
            <version>7.0</version>
        </dependency>

问题解决。项目结构如下：

2，现在整合spring+mybatis

pom.xml文件引入相关jar包,内附说明，

3、整合spring-mvc.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:p="http://www.springframework.org/schema/p"	xmlns:context="http://www.springframework.org/schema/context"	xmlns:mvc="http://www.springframework.org/schema/mvc"	xsi:schemaLocation="http://www.springframework.org/schema/beans                            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd                            http://www.springframework.org/schema/context                            http://www.springframework.org/schema/context/spring-context-3.1.xsd                            http://www.springframework.org/schema/mvc                            http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">	<!-- 自动扫描该包，[email protected] -->	<context:component-scan base-package="com.foresee.controller" />	<!--避免IE执行AJAX时，返回JSON出现下载文件 -->	<bean id="mappingJacksonHttpMessageConverter"		class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">		<property name="supportedMediaTypes">			<list>				<value>text/html;charset=UTF-8</value>			</list>		</property>	</bean>	<!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->	<bean		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">		<property name="messageConverters">			<list>				<ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 -->			</list>		</property>	</bean>	<!-- 定义跳转的文件的前后缀 ，视图模式配置 -->	<bean		class="org.springframework.web.servlet.view.InternalResourceViewResolver">		<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->		<property name="prefix" value="/WEB-INF/jsp/" />		<property name="suffix" value=".jsp" />	</bean>		<!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->	<bean id="multipartResolver"		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">		<!-- 默认编码 -->		<property name="defaultEncoding" value="utf-8" />		<!-- 文件大小最大值 -->		<property name="maxUploadSize" value="10485760000" />		<!-- 内存中的最大值 -->		<property name="maxInMemorySize" value="40960" />	</bean></beans>  

4、创建数据库foresee，创建user表

5、 实体类user.java

package com.foresee.pogo;public class User {    private int id;    private String userName;    private String password;	public int getId() {		return id;	}	public void setId(int 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;	}    }

6、映射文件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.foresee.dao.IUserDao">  <resultMap id="ResultMap" type="com.foresee.pogo.User">    <id column="id" property="id" jdbcType="INTEGER" />    <result column="userName" property="userName" jdbcType="VARCHAR" />    <result column="password" property="password" jdbcType="VARCHAR" />  </resultMap>    <select id="selectById" resultMap="ResultMap" parameterType="int" >    select id, userName, password    from user    where id = #{id}  </select>    <delete id="deleteById" parameterType="int" >    delete from user    where id = #{id}  </delete>    <insert id="addUser" parameterType="com.foresee.pogo.User" >    insert into user (id, userName, password)    values (#{id}, #{userName}, #{password})  </insert>    <update id="updateById" parameterType="com.foresee.pogo.User" >    update user    <set >      <if test="userName != null" >        userName = #{userName},      </if>      <if test="password != null" >        password = #{password},      </if>    </set>    where id = #{id}  </update>  </mapper>

7、DAO接口IUserDao.java

package com.foresee.dao;import com.foresee.pogo.User;public interface IUserDao {		public void deleteById(int id);		public void addUser(User user);	    public User selectById(int id);	    public void updateById(User user);}

8、建立service接口和实现类

package com.foresee.service;import com.foresee.pogo.User;public interface IUserService {     public User getUserById(int id);  }	

实现类

package com.foresee.serviceImpl;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.foresee.dao.IUserDao;import com.foresee.pogo.User;import com.foresee.service.IUserService;@Service("userService")public class IUserServiceImpl implements IUserService {	@Resource	private IUserDao userDao;		public User getUserById(int id) {		return this.userDao.selectById(id);	}}	

9、在webapp创建jsp文件

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  <html>    <head>      <title>测试</title>    </head>        <body>      ${user.userName}    </body>  </html> 

10、创建controller文件

package com.foresee.controller;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import com.foresee.pogo.User;import com.foresee.service.IUserService;@Controller  @RequestMapping("/user") public class UserController {	@Resource      private IUserService userService;            @RequestMapping("/showUser")      public String toIndex(HttpServletRequest request,Model model){          int id = Integer.parseInt(request.getParameter("id"));          User user = this.userService.getUserById(id);          model.addAttribute("user", user);          return "showUser";    }}

11、创建测试类

import javax.annotation.Resource;import org.apache.log4j.Logger;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.alibaba.fastjson.JSON;import com.foresee.pogo.User;import com.foresee.service.IUserService;@RunWith(SpringJUnit4ClassRunner.class)// 表示继承了SpringJUnit4ClassRunner类@ContextConfiguration(locations = { "classpath:spring-mybatis.xml" })public class TestMyBatis {	private static Logger logger = Logger.getLogger(TestMyBatis.class);	@Resource	private IUserService userService = null;	@Test	public void test1() {		User user = userService.getUserById(1);		 System.out.println(user.getUserName());		logger.info(JSON.toJSONString(user));	}}

测试结果

运行项目，利用jetty:run

run完毕，浏览器输入localhost:8080/mssm/user/showUser?id=1

这是一个和bug战斗的过程。
