使用Spring RestTemplate发布数据

Question

我正在尝试使用Spring RestTemplate发布数据，如下所示：

    MultiValueMap<String, String> parameters = new LinkedMultiValueMap<String, String>();
    parameters.add("name1", "value1");
    parameters.add("name2", "value2");

    HttpMessageConverter<String> stringConverter = new StringHttpMessageConverter();
    FormHttpMessageConverter formConverter = new FormHttpMessageConverter();
    List<HttpMessageConverter<?>> msgConverters = new ArrayList<HttpMessageConverter<?>>();
    msgConverters.add(formConverter);
    msgConverters.add(stringConverter);
    restTemplate.setMessageConverters(msgConverters);

    String xml = restTemplate.postForObject(myurl, parameters, String.class);

String name1 = request.getParameter("name1");

Cannot extract response: no Content-Type found

你能提供我一个简单的例子来实现我想要的。

下面是我用来格式化Spring Post数据的方法：

//FormHttpMessageConverter 

用于构造表单参数以发布在URI上

HttpMessageConverter<?> formHttpMessageConverter = new FormHttpMessageConverter();
HttpMessageConverter<?> stringHttpMessageConverter = new StringHttpMessageConverter();
List<HttpMessageConverter> msgConverters = new ArrayList<HttpMessageConverter>();
msgConverters.add(formHttpMessageConverter);
msgConverters.add(stringHttpMessageConverter);

// Prepare acceptable media type
List<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
acceptableMediaTypes.add(MediaType.ALL);

// Prepare header
HttpHeaders headers = new HttpHeaders();
headers.setAccept(acceptableMediaTypes);
HttpEntity<MultiValueMap<String,String>> httpEntity = new HttpEntity<MultiValueMap<String,String>>(map,headers);
ResponseEntity<String> resp = restTemplate.exchange("https://risk.XXXX.XXXXXX.net",HttpMethod.POST,httpEntity,String.class);
