javaweb项目部署后日志报错

Question

今天项目部署到服务器上时没报错，但是项目点击不了，查看日志时报这个错了：

 org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.aop.AopInvocationException: Null return value from advice does not match primitive return type for: public int com.lezhi.tyjyy.web.action.ProductInfoAction.edit(com.lezhi.tyjyy.model.validation.ProductInfo)

求大神指导下这是啥错，该怎么解决！！！！

Answer 1

int com.lezhi.tyjyy.web.action.ProductInfoAction.edit 返回String， int不行吧
