Question

我在spring mvc服务方法中运行调度程序。

我试图在没有httpRequest的情况下从会话中获取数据。

我搜索了一些方法，

我添加了一些想法

org.springframework.web.context.request.RequestContextListener

到web.xml听众。

但它不断给出错误信息： -

ERROR - TaskUtils$LoggingErrorHandler  :  handleError  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.

scheduler-context.xml： -

<task:scheduler id="scheduler" pool-size="100"/>
<task:scheduled-tasks scheduler = "scheduler">
    <task:scheduled ref="commonServiceImpl" method="autoCompute" cron = "0/5 * * * * *" />
</task:scheduled-tasks>

我试图获得会话的服务： -

@Service
public class CommonServiceImpl{
public void autoCompute(){

//      RequestAttributes requestAttributes = RequestContextHolder.currentRequestAttributes();
        RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
        System.out.println("test1");

        if(requestAttributes !=null);{
            ServletRequestAttributes attributes = (ServletRequestAttributes)     requestAttributes;
            System.out.println("test2");

            if(attributes !=null){
                System.out.println("test3");
                HttpServletRequest request = attributes.getRequest();
                HttpSession httpSession = request.getSession(true);

                String auto = (String) httpSession.getAttribute("auto");

                if(auto!=null){
                    System.out.println("schedule log"+auto);
                }
            }
        }
    }
}

我每5秒在控制台上得到的只是＆＃34; test1＆＃34;和＆＃34; test2＆＃34;

我检查了会话数据添加正确但仍然无法获取会话和服务中的数据...

需要一些帮助。谢谢！

“RequestContextFilter”也许这就是你要找的东西。

java.lang.IllegalStateException：找不到线程绑定请求：
