RestTemplate不适用于参数（URL，请求，类别<String>）

Question

我不能post请求RestTemplate。这表明在线

The method postForObject(URI, Object, Class<T>) in the type RestTemplate is 
not applicable for the arguments (URL, Request, 
Class<String>) 

代码

 URL url = new URL("http://testnl.etbxml.com/api"); 
     Authentication auth = new Authentication("Test", "test"); 
     auth.setFunction("SearchAvailability"); 

     Request req = new Request("test"); 
     req.setAuth(auth); 
     req.setCityid(23); 
     req.setStartdate("2015-11-20"); 
     req.setEnddate("2015-11-29"); 
     req.setRating(4); 
     req.setNoofpersons(2); 
     req.setLanguage("en"); 
     req.setCurrency("EUR"); 
     req.setCustomerIP(MY_IP); 
     req.setAuth(auth); 

     RestTemplate restTemplate = new RestTemplate(); 
     //restTemplate.getMessageConverters().add(new FormHttpMessageConverter()); 
     //restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter()); 
     //String response = restTemplate.postForObject(url, req, EasyToBook.class); 
     //Line 21 
     Easytobook ea = restTemplate.postForObject(url, req, String.class); 

     auth.setFunction("SearchAvailability"); 

Answer 1

您使用的是URL实例，但RestTemplate预计URI类型的对象以下错误。

只需更换这行：

URL url = new URL("http://testnl.etbxml.com/api"); 

这一行：

URI url = new URI("http://testnl.etbxml.com/api"); 

这应该做的伎俩。
