Mybatis的CRUD

@Test//增删改需要提交事物
    public void addUser(){
        SqlSession sqlSession = MybatisUtils.getSqlSession();
        UserMapper mapper = sqlSession.getMapper(UserMapper.class);
        int res = mapper.addUser(new User(4, "xiao", "1234567"));
        if(res>0){
            System.out.println("插入成功");
        }
        //提交事物
        sqlSession.commit();
        sqlSession.close();

    
        select * from mybatis.user
    

    
        select * from mybatis.user where id=#{id}
    
    
    
        insert into mybatis.user (id,name,pwd) values (#{id},#{name},#{pwd})
    

values 里面的值可以随便区名字
