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());
