三、解决方案
服务端一般要求json格式数据，所以不要把数据转为String，直接传输json数据即可解决。
restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8));JSONObject object = new JSONObject();object.put("depName","张三");object.put("userName","qwe");//String paramJson=object.toJSONString();// 直接传递object，不用传递paramJsonResponseEntity<String> responseEntity = restTemplate.postForEntity("http://127.0.0.1:8080/crmXXX/rest/webLineRecord/addLineRecord",object,String.class);System.out.println(responseEntity.getBody()) ;
