activiti中报错An Authentication object was not found in the SecurityContext

org.springframework.security.authentication.AuthenticationCredentialsNotFoundException: An Authentication object was not found in the SecurityContext

这是因为activiti7与springboot整合中集成了springsecurity

虽然你的用户赋予了权限

但是你执行方法的时候没有定义是哪个用户在执行方法

要不就整完全点写登录页面

要不就自定义用户去执行方法

securityUtil.logInAs(“zhangsan”);

下面是这个SecurityUtil
