SSM调用oracle存过，报Could not set property 'result' of 'class java.lang.Class' with value '1' Cause: org.

如图，存过没有入参，只有返回参数，

 

试了好多方法，都报错这个：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Could not set property 'result' of 'class java.lang.Class' with value '1' Cause: org.apache.ibatis.reflection.ReflectionException: There is no setter for property named 'result' in 'class java.lang.Class'

或者

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Could not set property 'result' of 'class java.lang.Class' with value '0' Cause: org.apache.ibatis.reflection.ReflectionException: There is no setter for property named 'result' in 'class java.lang.Class'

折腾了两天，终于解决，原来即使入参不用传，方法里面也要传一个Map，返回信息从Map中获取，
