一起学习Spring Boot 2.X | 第十一篇：Mybatis映射

• @Results对应resultMap
• @Result对应result 
• @ResultMap(“id”) 
• @Result中通过id属性引用这个resultMap
  
  
  注：column：数据库字段   property: 实体类字段

• @Select("SELECT id, name, password FROM user WHERE id = #{id}")
      @Results(id = "userMap", value = { @Result(column = "id", property = "id", javaType = Integer.class),
              @Result(column = "name", property = "name", javaType = String.class),
              @Result(column = "password", property = "password", javaType = String.class) })
      User findById(Integer id);
  
      @Select("SELECT * FROM user")
      @ResultMap("userMap")
      List<User> fingAll();
