Intellij IDEA +MAVEN+Jetty实现Spring整合Mybatis

1 pom.xml(这里出现transaction错误，是版本的问题)

2 model:Employee.java

 package com.mybatis.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+" ]" ;
     }
 }

3  mapper:EmployeeMapper.java

 package com.mybatis.mapper;

 import com.mybatis.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 getUserById(int id);

     @Select("select * from employee")
     List<Employee> getAllUsers();
 }

4 测试类

 package com.mybatis.test;

 import com.mybatis.mapper.EmployeeMapper;
 import com.mybatis.model.Employee;
 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 wanggenshen_sx on 2016/12/26.
  */
 @RunWith(SpringJUnit4ClassRunner.class)//使用Springtest框架
 @ContextConfiguration(locations={"classpath:spring-mybatis.xml"})//加载配置
 public class EmployeeTest {

     @Autowired  //注入
     private EmployeeMapper employeeMapper;
     /**
      * 根据一个id得到一条用户信息
      */
     /*@Test
     public void testGetUser(){
         SqlSession session = MybatisUtils.getSqlSessionFactory().openSession();
         EmployeeMapper mapper = session.getMapper(EmployeeMapper.class);

         Employee employee = mapper.getUserById(1);
         System.out.println("*"+employee);
         session.close();
     }*/

     @Test
     public void testGetUser(){
         Employee employee = employeeMapper.getUserById(1);
         System.out.println(employee);
     }

     /**
      * 得到所有用户信息
      */
     @Test
     public void testGetAllUsers(){
         List<Employee> employees = employeeMapper.getAllUsers();
         System.out.println(employees);
     }
 }

5 配置文件：spring-mybatis.xml（

sqlSessionFactoryBeanName与以前不一样
第3个步骤此处就是直接扫描包，而不用再在mybatis.xml中去注册EmployeeMapper接口

）
