本文解决了一个在使用MyBatis框架时遇到的问题，即在尝试获取名为readRoomID的属性时，由于该属性在java.lang.Integer类中不存在getter方法而引发的ReflectionException异常。通过在Mapper接口的方法参数上添加@Param注解，成功解决了这一问题。

错误代码：

public Integer getCountreadrooms(Integer readRoomID);

解决方案：加一个@Param 注解即可

public Integer getCountreadrooms(@Param("readRoomID") Integer readRoomID);
