Question

我有三个字段：SystemId，RegionCode和Locale。我必须使用RestTemplate在头文件中发送这三个字段。我正在使用此代码：

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));

HttpEntity<String> entity = new HttpEntity<String("RegionCode",regionCode);

restTemplate.exchange(url, HttpMethod.POST, entity, String.class);

如何在标题中添加其余两个字段？

Answer 1

也许您可以尝试以下方法：

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.put("RegionCode", regionCode);
headers.put("SystemId", systemId);
headers.put("Locale", locale);

HttpEntity<String> entity = new HttpEntity<String>(body,headers);

restTemplate.exchange(url, HttpMethod.POST, entity, String.class);

This is one of the example I have created:-

/********This is controller getMethod**********/

@RequestMapping(value = "/employee/{id}", method = RequestMethod.GET, produces = {MediaType.APPLICATION_JSON_VALUE,MediaType.APPLICATION_XML_VALUE})
    public ResponseEntity<Employee> getEmployee(@PathVariable("id") long id) {
        System.out.println("Fetching Employee with id " + id);
        Employee user = employeeService.findById(id);
        if (user == null) {
            System.out.println("Employee with id " + id + " not found");
            return new ResponseEntity<Employee>(HttpStatus.NOT_FOUND);
        }
        return new ResponseEntity<Employee>(user, HttpStatus.OK);
    }


/********This is client implementation**********/

@RequestMapping(value = "/employee/{id}", method = RequestMethod.GET, produces = {MediaType.APPLICATION_JSON_VALUE,MediaType.APPLICATION_XML_VALUE})
    public ResponseEntity<Employee> getEmployee(@PathVariable("id") long id) {
        System.out.println("Fetching Employee with id " + id);
        Employee user = employeeService.findById(id);
        if (user == null) {
            System.out.println("Employee with id " + id + " not found");
            return new ResponseEntity<Employee>(HttpStatus.NOT_FOUND);
        }
        return new ResponseEntity<Employee>(user, HttpStatus.OK);
    }
/*************Done**************/

/*******Output******/
