HTTP Status 500 - Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: There is no getter for property named 'parentid' in 'class java.lang.Integer'

There is no getter for property named 'parentid' in 'class java.lang.Integer'

解决方法1：
将参数名（上面的例子为’parentid’）替换为”_parameter” 


解决方法2：
Dao层接口方法的参数声明加上@Param("parentid")
如：List<PmClassify> getPmClassifyList(@Param(value = "parentid") Integerparentid);
