在新的线程中使用session 出现的问题

Exception in thread "Thread-15" 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.

解决方案1： 可以不要再新的线程中使用 Session ; 如果想要使用其中的数据，可以先在新线程外获取，再使用
