restTemplate Not enough variable values availabel

用 Spring RestTemplate 请求URL为"http://dffffff/fdsa?queryParam={\"fds\":\"www\"}"时报Not enough variable values availabel异常，其根本原因是RestTemplate认为大括号{…}在给定的URL作为一个URI变量占位符和试图取代他们，

可用queryParam={queryParam}替代

Map<String,Object> params = new HashMap<>();if(!StringUtils.isEmpty(mobile))   params.put("mobile", mobile);if(!StringUtils.isEmpty(userName))   params.put("name", userName);if(!StringUtils.isEmpty(email)){   params.put("email", email);String queryParam = JSONObject.valueToString(params);ResponseEntity<PSResponseData> entity = restTemplate.exchange(Constants.PS_WEB_URL + "esb/query/view?serviceCode=2001&consumerCode=10015&queryParam={queryParam}", HttpMethod.GET, null, PSResponseData.class,queryParam);
