Java spring和MessagesSource空指针异常
有人能告诉我为什么在Java spring和MessagesSource空指针异常,java,spring,hibernate,spring-mvc,Java,Spring,Hibernate,Spring Mvc,有人能告诉我为什么在messageSource的结果类中得到这个null指针异常吗 我已经注意到了这一点 并且可以在我的控制器中使用消息源，如下所示： 工作代码：--- 主要错误： web.service.common.Result.<init>(Result.java:29) web.service.UserServiceImpl.save(UserServiceImpl.java:30) web.controller.User
messageSourcenull指针异常吗
我已经注意到了这一点
并且可以在我的控制器中使用消息源，如下所示：
工作代码：---
主要错误：
