SSM简单整合

开发环境：JDK1.6 TOMCAT 7.0 MYSQL5.5 MyEclipse10

目录如下：

数据库如下：

User类：

package com.zh.pojo;public class User {private Integer id;private String username;private String password;private Integer age;public Integer getId() {return id;}public void setId(Integer 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 Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}}

UserServiceImpl类：

package com.zh.service.impl;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.zh.dao.IUserDao;import com.zh.pojo.User;import com.zh.service.IUserService;@Service("userService")public class UserServiceImpl implements IUserService {@Resource    private IUserDao userDao;@Overridepublic User getUserById(int id) { return userDao.findUserById(id);}}

IUserDao类：

package com.zh.dao;import com.zh.pojo.User;public interface IUserDao {User findUserById(Integer id);}

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.zh.dao.IUserDao">    <resultMap id="BaseResultMap" type="com.zh.pojo.User">        <id column="id" property="id" jdbcType="INTEGER"/>        <result column="username" property="username" jdbcType="VARCHAR"/>        <result column="password" property="password" jdbcType="VARCHAR"/>        <result column="age" property="age" jdbcType="INTEGER"/>    </resultMap>    <sql id="Base_Column_List">        id, username, password, age    </sql>    <select id="findUserById" resultMap="BaseResultMap" parameterType="java.lang.Integer">        select        <include refid="Base_Column_List"/>        from user_t        where id = #{id}    </select></mapper>

UserController：

package com.zh.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.zh.pojo.User;import com.zh.service.IUserService;@Controller  @RequestMapping("/user")  public class UserController {@Resource      private IUserService userService;            @RequestMapping("/index")      public String toIndex(HttpServletRequest request,Model model){          int userId = Integer.parseInt(request.getParameter("id"));          User user = this.userService.getUserById(userId);          model.addAttribute("user", user);          return "index";      }  }

index.jsp:

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

这样就搭建完成了，启动tomcat，在浏览器中输入localhost:8080/ssm/user/index?id=1
