使用spring的@Scheduled实现定时任务功能,运行时报错

错误信息如下:

2015-07-30 17:02:00,026 [pool-1-thread-1] ERROR: org.springframework.scheduling.support.TaskUtils$LoggingErrorHandler - Unexpected error occurred in scheduled task.
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.

Scheduled 是异步起线程来处理你的逻辑的
但你配置了 LogIntercept 这个拦截器, 里面的54行中, 会去调用RequestContextHolder.currentRequestAttributes, 但这个方法是需要有 http request 和 response 绑定到当前的线程中的.
由于你是使用的异步线程, 当然没有这个绑定了.
所以这个设计是有问题的. 不要在定时任务中使用 http request 和 response.
