一：项目结构

   二：导入jar包

  四、定义数据库操作

   实体Test.class

package main.dao.entity;

/**
 * Created by swordbone on 2017/11/29.
 */
public class Test {
    private Integer id;
    private String name;
    private Integer age;
    private String nickname;

    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;
    }

    public String getNickname() {
        return nickname;
    }

    public void setNickname(String nickname) {
        this.nickname = nickname;
    }

    @Override
    public String toString() {
        return "Test{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", nickName='" + nickname + '\'' +
                '}';
    }
}

    testMapper.xml文件

<?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">

            ID=#{id,jdbcType=INTEGER}
        </if>
    </delete>
</mapper>

  在同一目录下创建dao接口，注意接口中的方法名与map.xml文件中的sql语句id相同，参数返回值都要对应

   TestMapper.class

package main.dao.idao;

import main.dao.entity.Test;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by swordbone on 2017/11/29.
 */
@Repository
public interface TestMapper {
    Integer createTest(Test test);
    List<Test> queryTest(Test test);
    Integer updateTest(Test test);
    Integer deleteTest(Integer id);
}

  五、service层

    service接口：TestService.class

package main.service.iService;

import main.dao.entity.Test;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by swordbone on 2017/11/29.
 */

public interface TestService {
    Integer createTest(Test test);
    List<Test> queryTest(Test test);
    Integer updateTest(Test test);
    Integer deleteTest(Integer id);
}

   service实现类：TestServiceImpl.class

package main.service.serviceImpl;

import main.dao.entity.Test;
import main.dao.idao.TestMapper;
import main.service.iService.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by swordbone on 2017/11/29.
 */
@Repository
public class TestServiceImpl implements TestService {
//自动装载dao接口
    @Autowired
    private TestMapper testMapper;
    public Integer createTest(Test test) {
        return testMapper.createTest(test);
    }

    public List<Test> queryTest(Test test) {
        return testMapper.queryTest(test);
    }

    public Integer updateTest(Test test) {
        return testMapper.updateTest(test);
    }

    public Integer deleteTest(Integer id) {
        return testMapper.deleteTest(id);
    }
}

 六、jsp页面

  新建test页面：create.jsp

七、controller

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

/**

@Controller
@RequestMapping("/test")
public class TestController {
//   自动装载TestService接口
    @Autowired
    TestService testService;
//  查询所有的test
    @RequestMapping("/query")
    public String queryTest(ModelMap map, HttpServletRequest request, Test test){
        List<Test> list = testService.queryTest(test);
        map.addAttribute("list",list);
        return null;
    }
//    新建test
    @RequestMapping("/create")

        Integer returnnum = testService.createTest(test);
        map.addAttribute("returnnum",returnnum);
        return "redirect:/test/query.do";
    }
