Spring RestRemplate postforobject,请求参数具有整数值

我在Spring休息服务中有一个方法.

@RequestMapping(value = "test/process", method = RequestMethod.POST)
public @ResponseBody MyResponse processRequest(String RequestId, int count)

我正在使用Spring RestTemplate来调用此服务.

RestTemplate restTemplate = this.getRestTemplate();
MultiValueMap map = new LinkedMultiValueMap();
map.add("RequestId", RequestId);
map.add("count", count); 
restTemplate.postForObject(url, map,MyResponse.class);

当我尝试调用客户端方法时,我得到的异常是找不到合适的HttpMessageConverter请求类型[java.lang.Integer]

org.springframework.http.converter.HttpMessageNotWritableException: Could not write request: no suitable HttpMessageConverter found for request type [java.lang.Integer]

我知道其中一种方法是将所有参数作为String传递.但我可能需要稍后将复杂数据类型作为参数传递.有什么方法可以实现这一目标.我用谷歌搜索,一些选项似乎是编写我自己的转换器.我应该如何开始解决这个问题.
