spring RestTemplate submit json format data

 RestTemplate spring is encapsulated, easier to use.

 

receive:

@ApiOperation(value = "restTemplate测试", notes = "restTemplate测试", httpMethod = "POST", response = BaseResult.class)
    @ApiImplicitParams({})
    @RequestMapping(value = "/restTemplateTest.do", method = RequestMethod.POST)
    public @ResponseBody
    Map<String, Object> restTemplateTest(HttpServletRequest request, @RequestBody Map<String, Object> params) throws Exception {
        Map<String, Object> result = getParams(request);
        try {
            System.out.println(params);
            result.put("isLog", false);
            result.put("success", true);
            result.put("msg", "测试成功");
        } catch (Exception e) {
            e.printStackTrace();
            result.put("isLog", false);
            result.put("success", false);
            result.put("msg", "测试失败:" + e.getMessage());
        }
        return result;
    }

 

Note here can obtain annotation request body parameters @RequestBody

 

request:

    @ApiImplicitParams({})
    @RequestMapping(value = "/testRestTemplate.do", method = RequestMethod.POST)

            factory.setReadTimeout(10000);//单位为ms
            factory.setConnectTimeout(10000);//单位为ms
            RestTemplate restTemplate = new RestTemplate(factory);
            String url = "http://192.168.71.179:8080/xxxx/restTemplateTest.do";

            // URL request method type PARAMETERS return type 
            ResponseEntity <the Map> = restTemplate.exchange Exchange (URL, HttpMethod . .POST, HttpEntity, the Map class ); 
            the Map body = exchange.getBody (); 
            System.out.println (JSON.toJSONString (body));

            result.put ( " MSG "," successful test " ); 
        } the catch (Exception e) {
            e.printStackTrace();
            result.put("isLog", false);
