当我没有请求范围时，我有一些问题要忽略db.patients.aggregate([
{$sort:{dateOfBirth: -1}},
{$limit:3}
])
。我可以解释一下。
我使用Hibernate Envers在审计表中保存用户的一些信息。当存在请求（来自我的Rest Controller）时，这很有效，因为需要记录用户，因此在这种情况下总能找到用户。
但是，我也在和RabbitMQ合作。当我收到一些需要对数据库执行某些操作的消息时（按示例插入实体），我的代码尝试从应用程序上下文加载@Scope bean。 User Bean与User请求绑定，Spring无法找到线程绑定请求。
所以，我收到错误：
@Scope我想忽略这种情况，因为我在这种情况下的意图是填写＆＃34;用户＆＃34;有关＆＃34; system＆＃34;等信息的信息。表示此更改不是由用户直接进行的（因为没有用户参与）。
我的代码如下。
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.get': Scope 'request' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

（Hibernate Envers）：
RevisionEntityListener我的@Component
public class RevisionEntityListener implements RevisionListener, ApplicationContextAware {
private static ApplicationContext applicationContext;
@Override
public void newRevision(Object revisionEntity) {
RevEntity revEntity = (RevEntity) revisionEntity;
User user = applicationContext.getBean(User .class);
revEntity.setUserId(user.getUserId());
// code
}
private static void setStaticApplicationContext(ApplicationContext context) {
applicationContext = context;
}
@Override
public void setApplicationContext(ApplicationContext applicationContext)
throws BeansException {
setStaticApplicationContext(applicationContext);
}
}

UserConfiguration答案 0 :(得分：1)
我不会＆＃39;知道这是否是最佳选择，但我创建了一个if以查看SecurityContextHolder.getContext().getAuthentication()是否存在：
User user;
if (SecurityContextHolder.getContext().getAuthentication() != null) {
user = applicationContext.getBean(User .class);
} else {
user = createSystemUser();
}
revEntity.setUserId(user.getUserId());
