Spring RestTemplate get post 请求 携带 headers

RestTemplate

  1.我用RestTemplate请求时 我把他注入到容器里  这样可以 什么用什么时候拿

  2.也可以new出来 不过我不喜欢 所以就没有用new的

下面我自己的方法   先注入到容器 在 xxx-service.xml 里加上

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate" ></bean>

然后用的时候

  @Autowired
private RestTemplate restTemplate;

get

@Override
public String seleteAllSeasonMatch(){
String url = xxx+"Season?seasontype=2";
HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA);
httpHeaders.add("xxx",DATAVOLLEY_KEY);
HttpEntity<MultiValueMap> requestEntity = new HttpEntity<MultiValueMap>( httpHeaders);
ResponseEntity<String> responseEntity =restTemplate.exchange(url,HttpMethod.GET,requestEntity,String.class);
String result = responseEntity.getBody();
System.out.println(result);;
return "";
}

post

     HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.add("xxx", "1.0");
//body
MultiValueMap<String, String> requestBody = new LinkedMultiValueMap<>();
requestBody.add("xxx", "1");
//HttpEntity
HttpEntity<MultiValueMap> requestEntity = new HttpEntity<MultiValueMap>(requestBody, requestHeaders);
//post
ResponseEntity<String> responseEntity = restTemplate.postForEntity("http://xxx", requestEntity, String.class);
System.out.println(responseEntity.getBody());
