cxf webclient - 異常[請求處理失敗;嵌套的異常是狀態：406

我在使用CXF webclient時遇到以下錯誤（406），但是當我使用URL API時，我得到了預期的輸出。cxf webclient - 異常[請求處理失敗;嵌套的異常是狀態：406

我的客戶端代碼：

 URL url = new URL("http://localhost:8080/assignment/cxf/login/"+name+"/"+password); 
     HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
     conn.setRequestMethod("GET"); 
     conn.setRequestProperty("Accept", "application/json"); 
     BufferedReader br = new BufferedReader(new InputStreamReader(
      (conn.getInputStream()))); 
     StringBuilder res = new StringBuilder(); 
     String output; 
     while ((output = br.readLine()) != null) { 
      res.append(output); 
     } 
     System.out.println("Result-->"+res.toString()); 
     WebClient webClient = WebClient.create("http://localhost:8080/assignment/cxf/login/"+name+"/"+password);    
    // WebClient t = webClient.path(""); 
     String res = webClient.accept("text/xml").get(String.class); 
     System.out.println("=============="+res);

REST端點服務類：

@GET 
    @Path("/login/{userName}/{password}") 
    @Produces({MediaType.APPLICATION_JSON, MediaType.TEXT_XML }) 
    public String userLogin(@PathParam("userName")String username, @PathParam("password")String password) 
      throws JAXBException, PropertyException, FileNotFoundException {

問題

1）什麼改變，我需要做，修復錯誤

2）作爲Json返回，我需要做什麼更改？如果我寫，conn.setRequestProperty（「Accept」，「application/xml」）;我得到錯誤。

實測溶液：

客戶端更改：

WebClient webClient = WebClient.create("http://localhost:8080/assignment/cxf/login/test/test1");    
String res = webClient.accept("application/xml").get(String.class);

這裏代替String res = webClient.accept("text/xml").get(String.class);製成

String res = webClient.accept("application/xml").get(String.class);

服務類的變化：

@GET 
    @Path("/login/{userName}/{password}") 
    @Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML }) 
    @Consumes({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML}) 
    public String userLogin(@PathParam("userName")String username, @PathParam("password")String password)

在userLogin方法中改爲MediaType.APPLICATION_XML而不是MediaType.TEXT_XML

根據HTTP規範，406響應意味着服務器不能滿足請求的ACCEPT標頭中所述的要求。但是，服務器端日誌消息似乎暗示其他事情正在發生。

我建議你做什麼日誌消息建議。啓用調試日誌記錄並查看細粒度的日誌消息對發生什麼問題的說明。
