下载各种jar包

　　mybatis下载

https://github.com/mybatis/mybatis-3/releases

技术分享图片

　　mysql驱动下载

http://mvnrepository.com/artifact/mysql/mysql-connector-java

　　spring下载(spring所用到的所有jar包，包括springmvc)

http://repo.spring.io/release/org/springframework/spring/

　　配合spring使用的工具类收录（开发包大全），最终版本3.0.2，后面就不更新了。

　　需要用到的jar：

aopalliance jar包 AOP联盟的API包,里面包含了针对面向切面的接口。通常Spring等其它具备动态织入功能的框架依赖此包
aspectjweaver-1.6.11.jar aspectjweaver是spring的切入点表达式需要用的包

　springmvc.xml

配置Controller扫描
配置注解驱动
视图解释器

静态页面，如html,css,js,images可以访问

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

　web.xml

spring的配置文件
处理POST提交乱码问题
配置SpringMVC前端控制器

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

至此框架就算搭建完成了，然后就是测试环节

新建一个student表

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for `student`
-- ----------------------------
DROP TABLE IF EXISTS `student`;
CREATE TABLE `student` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(20) DEFAULT NULL,
  `age` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of student
-- ----------------------------
INSERT INTO `student` VALUES (‘1‘, ‘张三‘, ‘18‘);
INSERT INTO `student` VALUES (‘2‘, ‘李四‘, ‘15‘);
INSERT INTO `student` VALUES (‘3‘, ‘王五‘, ‘20‘);
INSERT INTO `student` VALUES (‘4‘, ‘赵六‘, ‘22‘);
INSERT INTO `student` VALUES (‘5‘, ‘孙琪‘, ‘24‘);
INSERT INTO `student` VALUES (‘6‘, ‘路飞‘, ‘19‘);

创建student pojo对象

package com.ssm.pojo;

import java.io.Serializable;

/**
 * Created by ${DX} on 2018/9/28.
 */
public class Student {

    private int id;
    private String name;
    private int age;

    public Student(int id, String name, int age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }

    @Override
    public String toString() {
        return "Student{" +
                "id=" + id +
                ", name=‘" + name + ‘‘‘ +
                ", age=" + age +
                ‘}‘;
    }

    public int getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

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

View Code

StudentDao

package com.ssm.dao;

import com.ssm.pojo.Student;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by ${DX} on 2018/9/28.
 */
@Repository
public interface StudentDao {

    List<Student> findAllStudent();
}

View Code

StudentDao.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.ssm.dao.StudentDao">
    <select id="findAllStudent" resultType="Student">
        SELECT * FROM student;
    </select>
</mapper>

View Code

测试方法StudentDaoTest

package test;

import com.ssm.dao.StudentDao;
import com.ssm.pojo.Student;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.List;

/**
 * Created by ${DX} on 2018/9/28.
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class StudentDaoTest {

    @Autowired
    private StudentDao studentDao;

    @Test
    public void test(){


        List<Student> students=studentDao.findAllStudent();
        System.out.println(students.size());

    }

}

测试通过

接下来是service层

StudentService

package com.ssm.service;

import com.ssm.pojo.Student;

import java.util.List;

/**
 * Created by ${DX} on 2018/9/29.
 */
public interface StudentService {

    List<Student> findAllStudent();
}

StudentServiceImpl

package com.ssm.service;

import com.ssm.dao.StudentDao;
import com.ssm.pojo.Student;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Created by ${DX} on 2018/9/29.
 */
@Service
public class StudentServiceImpl implements  StudentService {

    @Autowired
    private StudentDao studentDao;

    @Override
    public List<Student> findAllStudent() {
        return studentDao.findAllStudent();
    }
}

StudentSeviceTest

package test;

import com.ssm.pojo.Student;
import com.ssm.service.StudentService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.List;

/**
 * Created by ${DX} on 2018/9/29.
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class StudentSeviceTest {

    @Autowired
    private StudentService studentService;

    @Test
    public void test(){
        List<Student> students=studentService.findAllStudent();
        System.out.println(students.size());
    }

}

service层测试通过

最后就是controller层

StudentController

package com.ssm.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created by ${DX} on 2018/9/29.
 */

@Controller
@RequestMapping("/student")
public class StudentController {

    @RequestMapping("/index")
    public String index(){
        return "hello";
    }


}

hello.jsp

<%--
  Created by IntelliJ IDEA.
  User: Administrator
  Date: 2018/9/29
  Time: 0:11
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    HELLO SSM！！！！
</body>
</html>

开启服务器后，页面访问/student/index 就会跳转到hello.jsp 页面

至此 ssm 框架搭建测试完毕！！！
