cxf webclient - 异常[请求处理失败;嵌套的异常是状态：406

我在使用CXF webclient时遇到以下错误（406），但是当我使用URL API时，我得到了预期的输出。cxf webclient - 异常[请求处理失败;嵌套的异常是状态：406

我的客户端代码：

 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端点服务类：

@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 {

问题

1）什么改变，我需要做，修复错误

2）作为Json返回，我需要做什么更改？如果我写，conn.setRequestProperty（“Accept”，“application/xml”）;我得到错误。

实测溶液：

客户端更改：

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

这里代替String res = webClient.accept("text/xml").get(String.class);制成

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

服务类的变化：

@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方法中改为MediaType.APPLICATION_XML而不是MediaType.TEXT_XML

根据HTTP规范，406响应意味着服务器不能满足请求的ACCEPT标头中所述的要求。但是，服务器端日志消息似乎暗示其他事情正在发生。

我建议你做什么日志消息建议。启用调试日志记录并查看细粒度的日志消息对发生什么问题的说明。
