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());
