如何从POST请求获取响应对象？

Question

这是一个Spring应用程序，我试图做一个POST请求并获取响应。

在服务器端我有这个

@CrossOrigin 
@RequestMapping(value = "/test", method = RequestMethod.POST) 
public 
@ResponseBody 
Test testmethod(@RequestBody Test test) { 
    test.setValue("test"); 
return test; 
} 

在客户端我有POST方法应该返回测试对象。我使用JSON进行编码。

public Object post(String url1, Test test) throws IOException, ClassNotFoundException { 

    ObjectMapper mapper = new ObjectMapper(); 
    String jsonInString = mapper.writeValueAsString(login); 

    try { 

     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     HttpPost postRequest = new HttpPost(url1); 

     StringEntity input = new StringEntity(jsonInString); 
     input.setContentType("application/json"); 
     postRequest.setEntity(input); 

     HttpResponse response = httpClient.execute(postRequest); 

     //read the object from the response, how to do that? 
     //responseObject = ????? 

     httpClient.getConnectionManager().shutdown(); 

    } catch (MalformedURLException e) { 

     e.printStackTrace(); 

    } catch (IOException e) { 

     e.printStackTrace(); 

    } 
return responseObject; 
} 

而且

Test s = new Test; 
Test s=(Test)post("http://localhost:8081/basic-web-app/test",s); 

我的问题是，我不知道烫得到响应测试对象。请帮忙。谢谢！

你可以尝试使用：

String responseAsString = EntityUtils.toString(response.getEntity());
