Apache cxf服務器異步請求處理

嗨，我需要在apache cxf服務器中實現異步處理請求。到目前爲止，我認爲我需要添加AsyncResponse請求。但它沒有奏效。Apache cxf服務器異步請求處理

@GET 
@Path("/test") 
@Produces(MediaType.APPLICATION_XML) 
@Consumes(MediaType.APPLICATION_XML) 
void sample(@Suspended AsyncResponse asyncResponse); 

@Override 
    public void sample(AsyncResponse asyncResponse) { 
     asyncResponse.setTimeout(3, TimeUnit.MINUTES); 
     asyncResponse.setTimeoutHandler(new TimeoutHandler() { 
      @Override 
      public void handleTimeout(AsyncResponse asyncResponse) { 
       asyncResponse.resume("Sample"); 
      } 
     }); 

    }

當我發送請求到終點時，它會拋出異常。

我想知道我實現了異步是正確的道路，如果它是什麼，是我的執行問題的方式。

不知道你是否仍在尋找答案。您的實現看起來很好，通過查看堆棧跟蹤，似乎服務器無法正確理解請求。如果您正在使用任何過濾器，請檢查web.xml。過濾器應該具有此屬性（true）以支持異步調用。

你的過濾器應該應該尋找這樣的..

<filter> 
    <filter-name>XXXXXX</filter-name> 
    <filter-class>xxx.xxx.xxx.XXXXXX</filter-class> 
    <async-supported>true</async-supported> 
</filter>
