【SSM】Eclipse使用Maven创建Web项目+整合SSM框架

转载自：http://blog.csdn.net/liweizhong193516/article/details/53612857（可用）

 自己接触ssm框架有一段时间了，从最早的接触新版ITOO项目的（SSM/H+Dobbu zk），再到自己近期来学习到的《淘淘商城》一个ssm框架的电商项目。用过，但是还真的没有自己搭建过，一直都是用别人搭建好的。所以，从网上找了一些材料，结合自己来解决过程中的一些问题，使自己对ssm框架理解更加深了，不为分享，只是总结一下，下次有机会再搭建的时候，直接看自己的博客，省得找了！

一、准备环境：

       maven：apache-maven-3.2.3

       jdk：jdk1.8.0_25

       tomcat：tomcat-6.0.37

       mysql：阿里云centos7 搭建的mysql

二、配置Maven、jdk

     1、Window——>Preferences——>Maven——>设置自己的Settings

     2、Window——>Preferences——>Java——>Installed JREs——>Add

              

     配置好maven之后，就可以在本地设置好的地方看到对应的Maven文件了，还有包含resp文件夹

三、新建Maven项目：

     1、右击——>New（或者是File——>New）——>other——>Maven——>Maven Project——>Next

           

           

2、这时候，我们就成功创建出一个Maven项目了，项目结构如下图：

          

       到这里，我们的Maven项目就建好了，接下来，我们来整合搭建SSM（Spring MVC + Spring + Mybatis）

首先我们来配置一些整合框架所必须要的jar包，也就是来配置我们的pom文件，然后直接alt+f5，保存后，就会自动下载，存放在之前配置好的本地maven仓库中。

pox.xml配置依赖的内容：

2、在src/main/resources下添加配置文件：spring-mybatis.xml

 xml version="1.0" encoding="UTF-8"?>

配置数据库连接池：jdbc.properties

配置日志：log4j.properties

 log4j.rootLogger=INFO,Console,File

接下来，我们来整合spring mvc：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"

修改web.xml

到这里，我们的ssm框架就完成了，下面，我们来个实现：

在src/main/java下分别添加我们的dao包，service包，还有controller包.包里面添加相应的类，效果图如下：

UserController.java:

 package com.cn.hnust.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.cn.hnust.pojo.User;
 import com.cn.hnust.service.IUserService;

 @Controller
 @RequestMapping("/user")
 public class UserController {
       @Resource
         private IUserService userService;

         @RequestMapping("/showUser")
         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 "showUser";
         }
 }

IUserDao.java:

 package com.cn.hnust.dao;

 import com.cn.hnust.pojo.User;

 public interface IUserDao {

     public User selectByPrimaryKey(int userId) ;
 }

User.java:

 package com.cn.hnust.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 == null ? null : userName.trim();
     }

     public String getPassword() {
         return password;
     }

     public void setPassword(String password) {
         this.password = password == null ? null : password.trim();
     }

     public Integer getAge() {
         return age;
     }

     public void setAge(Integer age) {
         this.age = age;
     }
 }

UserMapper.xml:

 xml version="1.0" encoding="UTF-8"?>
 >
 <mapper namespace="com.cn.hnust.dao.IUserDao">
   <resultMap id="BaseResultMap" type="com.cn.hnust.pojo.User" >
     <id column="id" property="id" jdbcType="INTEGER" />
     <result column="user_name" 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, user_name, password, age
   sql>
   <select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.Integer" >
     select
     <include refid="Base_Column_List" />
     from user_t
     where id = #{id,jdbcType=INTEGER}
   select>
 mapper>

IUserService.java:

 package com.cn.hnust.service;

 import com.cn.hnust.pojo.User;

 public interface IUserService {
     public User getUserById(int userId);
 }

UserServiceImpl.java:

 package com.cn.hnust.service.impl;

 import javax.annotation.Resource;

 import org.springframework.stereotype.Service;

 import com.cn.hnust.dao.IUserDao;
 import com.cn.hnust.pojo.User;
 import com.cn.hnust.service.IUserService;

 @Service("userService")
 public class UserServiceImpl implements IUserService {
     @Resource
     private IUserDao userDao;

     public User getUserById(int userId) {
         return this.userDao.selectByPrimaryKey(userId);
     }
 }

接下来就是我们的静态页面了jsp文件了，在WEB-INF文件夹下新建jsp文件夹，添加userinfo.jsp

showUser.jsp:

 <%@ page language="java" contentType="text/html; charset=UTF-8"
