Bean property ‘mapperHelper’ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
spring boot 报错: Caused by: org.springframework.beans.NotWritablePropertyException:
Invalid property ‘mapperHelper’ of bean class [org.mybatis.spring.mapper.MapperFactoryBean]:
Bean property ‘mapperHelper’ is not writable or has an invalid setter method.
Does the parameter type of the setter match the return type of the getter?
原因是:通用mapper不支持热部署,不支持devtool。
解决方法:在pom.xml屏蔽掉热部署就OK了。
<!-- 热启动配置 -->
