Spring-Mybatis

1. 导包

   
        
            junit
            junit
            4.12
        
        
            mysql
            mysql-connector-java
            5.1.47
        
        
            org.mybatis
            mybatis
            3.5.2
        
        
            org.springframework
            spring-webmvc
            5.1.9.RELEASE
        
        
        
            org.springframework
            spring-jdbc
            5.1.9.RELEASE
        
        
            org.aspectj
            aspectjweaver
            1.8.13
        
        
            org.mybatis
            mybatis-spring
            2.0.2
        
        
            org.projectlombok
            lombok
            1.18.10
        
    

2. 编写数据源配置

3. sqlSessionFactory

4. sqlSessionTemplate

5. 需要给接口添加实现类

   public class UserMapperImpl implements UserMapper{
   
    //我们的所有操作，在原来都使用sqlSession来执行，现在都使用SqlSessionTemple
    private SqlSessionTemplate sqlSession;
   
    public void setSqlSession(SqlSessionTemplate sqlSession) {
        this.sqlSession = sqlSession;
    }
   
    public List selectUser() {
        UserMapper mapper = sqlSession.getMapper(UserMapper.class);
        return mapper.selectUser();
    }
   }

6. 将自己写的实现类注入到spring中

7. 测试使用

   ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
   UserMapper userMapper = context.getBean("userMapper", UserMapper.class);
   List userList = userMapper.selectUser();
   for (User user : userList) {
    System.out.println(user);
   }
