2 建java包后建实体类： 利用Intellij+MAVEN完成Spring整合Mybatis项目详解 实体类Employee.java 
package com.springmybatis.model;

/**
 * Created by wanggenshen_sx on 2016/12/23.
 */
public class Employee {

private int id;
private String lastName;
private String email;

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return "Employee [id=" + id + ", lastName=" + lastName + ", email="
+ email+" ]" ;
}
}
EmployeeMapper.java，采用的注解的方式,即@Select 
package com.springmybatis.service;

import com.springmybatis.model.Employee;
import org.apache.ibatis.annotations.Select;

import java.util.List;


/**
 * Created by wanggenshen_sx on 2016/12/26.
 */
public interface EmployeeMapper {

@Select("select id,lastName,email from employee where id=#{id}")
Employee findById(int id);

@Select("select id,lastName,email from employee")
List<Employee> findAll();
}

   测试类：SpringMybatisTest1.java
package com.springmybatis.test;

import com.springmybatis.model.Employee;
import com.springmybatis.service.EmployeeMapper;
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 javax.sql.DataSource;
import java.util.List;

/**
 * Created by wanggenshen_sx on 2016/12/26.
 */
@RunWith(SpringJUnit4ClassRunner.class)//使用Springtest框架
@ContextConfiguration(locations={"classpath:spring.xml"})//加载配置
public class SpringMybatisTest1 {
@Autowired
private EmployeeMapper employeeMapper;

@Test
public void getUser(){
Employee user = employeeMapper.findById(1);
System.out.println(user);
}

@Test
public void findAll(){
List<Employee> users = employeeMapper.findAll();
System.out.println(users);
}
@Test
public void test(){
System.out.println(12);
}


}


 3 编写spring配置文件，整合mybatis.注意这里使用的事EmployeeMapper接口，采用的是注解的方式，所以要在配置文件中去注册这个接口。（如果用配置文件的方式就是要注册对应接口的xml文件）
