使用Maven搭建SSM环境，废话不多说现在开始！

使用Eclipse创建Maven项目：

![20180103192313220][]

![20180103192324976][]

点击finish后生成的结构如下：

2、配置pom.xml：

配置完pom.xml后Maven install将包导入：

![20180103193318923][]

打开Java Build Path后勾选Maven Dependencies 点击应用

![20180103193602690][]

切换到Libraries将原来的jre1.5 remove 加入本地1.8kre 并且加入Apache Tomcat运行环境

![20180103193803725][]

上述步骤做完后项目目录如下：

![20180103194043981][]

在src/main/下创建config文件夹并且将config加入Source Folder

![20180103194625476][]

之后在config下创建配置文件：

为了防止出现not found class 异常  需要将Maven Dependencies加入Deployment Assembly中：

![20180103200024692][]

![20180103200041337][]

最后在src/main/java中创建如下文件：

![20180103200259970][]

UserMapper.java:

package com.iss.mapper;
    
    import java.util.List;
    
    import com.iss.entity.User;
    
    /**
     * 
     * @author liu
     *
     */
    public interface UserMapper {
    	/**
    	 * 返回所有用户的集合
    	 * @return List<User>
    	 */
    	public List<User> selectAll();
    
    }

User.java:

package com.iss.entity;
    /**
     * 
     * @author liu
     *
     */
    public class User {
    	private Integer id;
    	private String name;
    	private Integer age;
    	public Integer getId() {
    		return id;
    	}
    	public void setId(Integer id) {
    		this.id = id;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public Integer getAge() {
    		return age;
    	}
    	public void setAge(Integer age) {
    		this.age = age;
    	}
    	@Override
    	public String toString() {
    		return "User [id=" + id + ", name=" + name + ", age=" + age + "]";
    	}
    }

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.iss.mapper.UserMapper">
    	<resultMap type="com.iss.entity.User" id="BaseResultMap">
    		<id column="id" property="id" />
    		<result column="name" property="name" />
    		<result column="age" property="age" />
    	</resultMap>
    
    	<sql id="Base_Column_List">
    		id,name,age
    	</sql>
    
    	<select id="selectAll" resultMap="BaseResultMap">
    		select
    		<include refid="Base_Column_List"></include>
    		from user
    	</select>
    
    </mapper>

UiController.java:

package liumu.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import com.iss.mapper.UserMapper;
    @Controller
    @RequestMapping("/main")
    /**
     * 
     * @author liu
     *
     */
    public class UiController {
    	@Autowired
    	private UserMapper userMapper;
    	
    	@RequestMapping("index")
    	public void indexUi() {
    		System.out.println(userMapper.selectAll());
    		
    	}
    }

最后需要一个数据库测试文件：

CREATE TABLE IF NOT EXISTS `user` (
      `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
      `name` varchar(50) DEFAULT NULL,
      `age` int(10) unsigned DEFAULT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
    
    
    INSERT INTO `user` (`id`, `name`, `age`) VALUES
    	(1, 'Neo', 35),
    	(2, 'Jerry', 36);

在浏览器中 http://localhost:8081/Test/main/index 可以看到查询出了user的信息。一个简单的SSM就成功啦
