    http://localhost:9093/myTestHttp?name=1 访问
    @ResponseBody
    public TestReponse myTestHttp(TestRequest request){// name为属性值

@Autowired

        HttpHeaders hh = new HttpHeaders();
        hh.setContentType(new MediaType("application","json", Charset.forName("UTF-8")));
        hh.setAccept(Arrays.asList(new MediaType("application","json", Charset.forName("UTF-8"))));

        HttpEntity<String> he = new HttpEntity<String>(s.toString(),hh);
        ResponseEntity<String> ex = rest.exchange("http://localhost:9093/myTestHttp", HttpMethod.POST,he,String.class);
//        ResponseEntity<String> ex = rest.postForEntity("http://localhost:9093/myTestHttp",he,String.class);

        String res = ex.getBody();
        System.out.println(" res: "+res);
提供者
      public TestReponse myTestHttp(TestRequest request){// name为属性值
结果：
访问者用json方式请求name值无法传递
public TestReponse myTestHttp(String name,String age){  //提供者如此修改，可接收name    
必须有  MappingJackson2HttpMessageConverter @@@待解决
public TestReponse myTestHttp(@RequestBody Map<String,String> request){ //提供者如此修改，可接收name
