澤西島和weblogic服務器發送的事件

我正在試驗服務器發送的事件。我正在關注這個鏈接https://jersey.java.net/documentation/latest/user-guide.html#d0e8376。當我向代表服務器發送事件的資源發出請求時，我得到500內部服務器錯誤。澤西島和weblogic服務器發送的事件

根據以下錯誤，我必須爲org.glassfish.jersey.media.sse.EventOutput註冊正文作者。但是，怎麼做呢？

下面是我自己的問題的解決方案。

要註冊SseFeature，應該在Application派生類中重寫getSingletons方法，如下面的代碼所示。

@javax.ws.rs.ApplicationPath("webresources") 
public class ApplicationConfig extends Application { 

    //.... 

    @Override 
    public Set<Object> getSingletons() { 
     Set<Object> singletons = super.getSingletons(); 
     if(singletons == null){ 
      singletons=new java.util.HashSet<Object>(); 
     } 
     singletons.add(new SseFeature()); 
     return singletons; 
    } 

    //.... 

}

老問題，但你只需要添加的功能，這樣的'''寄存器（ SseFeature.class）''' – Quaiks
