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

 1 package com.mybatis.model;
 2 
 3 /**
 4  * Created by wanggenshen_sx on 2016/12/23.
 5  */
 6 public class Employee {
 7 
 8     private int id;
 9     private String lastName;
10     private String email;
11 
12     public int getId() {
13         return id;
14     }
15     public void setId(int id) {
16         this.id = id;
17     }
18     public String getLastName() {
19         return lastName;
20     }
21     public void setLastName(String lastName) {
22         this.lastName = lastName;
23     }
24     public String getEmail() {
25         return email;
26     }
27     public void setEmail(String email) {
28         this.email = email;
29     }
30     @Override
31     public String toString() {
32         return "Employee [id=" + id + ", lastName=" + lastName + ", email="
33                 + email+" ]" ;
34     }
35 }

3 mapper:EmployeeMapper.java

 1 package com.mybatis.mapper;
 2 
 3 import com.mybatis.model.Employee;
 4 import org.apache.ibatis.annotations.Select;
 5 
 6 import java.util.List;
 7 
 8 /**
 9  * Created by wanggenshen_sx on 2016/12/26.
10  */
11 
12 public interface EmployeeMapper {
13     @Select("select id,lastName,email from employee where id=#{id}")
14     Employee getUserById(int id);
15 
16     @Select("select * from employee")
17     List<Employee> getAllUsers();
18 }

4 测试类

 1 package com.mybatis.test;
 2 
 3 import com.mybatis.mapper.EmployeeMapper;
 4 import com.mybatis.model.Employee;
 5 import org.junit.Test;
 6 import org.junit.runner.RunWith;
 7 import org.springframework.beans.factory.annotation.Autowired;
 8 import org.springframework.test.context.ContextConfiguration;
 9 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
10 
11 import java.util.List;
12 
13 /**
14  * Created by wanggenshen_sx on 2016/12/26.
15  */
16 @RunWith(SpringJUnit4ClassRunner.class)//使用Springtest框架
17 @ContextConfiguration(locations={"classpath:spring-mybatis.xml"})//加载配置
18 public class EmployeeTest {
19 
20 
21     @Autowired  //注入
22     private EmployeeMapper employeeMapper;
23     /**
24      * 根据一个id得到一条用户信息
25      */
26     /*@Test
27     public void testGetUser(){
28         SqlSession session = MybatisUtils.getSqlSessionFactory().openSession();
29         EmployeeMapper mapper = session.getMapper(EmployeeMapper.class);
30 
31         Employee employee = mapper.getUserById(1);
32         System.out.println("*"+employee);
33         session.close();
34     }*/
35 
36     @Test
37     public void testGetUser(){
38         Employee employee = employeeMapper.getUserById(1);
39         System.out.println(employee);
40     }
41 
42     /**
43      * 得到所有用户信息
44      */
45     @Test
46     public void testGetAllUsers(){
47         List<Employee> employees = employeeMapper.getAllUsers();
48         System.out.println(employees);
49     }
50 }

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

）
