详解使用Spring的restTemplete进行Http请求

最近学习Spring框架，本文介绍了使用Spring的restTemplete进行Http请求，留个笔记

public class RestTemplateTest {
  //private static String url = "http://10.2.1.46:8080";
  private static String url = "http://127.0.0.1:8080/test";
  private static String autoDeploy = "/api/ddd/manages/yyy/1111";

  public static void main(String[] args) throws UnsupportedEncodingException {
    JSonObject token1 = LoginTest.login(url);
    JSonObject token = new JSonObject();
    token.put("token", token1.getString("token"));
    token.put("userName", "chenchen.ming@56qq.com");
    String name = "明辰晨";
    token.put("name", URLEncoder.encode(name, "UTF-8"));

    String jsonBody = DmsAutoDeployTest.dmsAutoDeployData();
    autoDeploy(jsonBody,token.toJSonString());
  }

  
  public static void autoDeploy(String json,String token){
    String autoDeployUrl = url + autoDeploy;
    RestTemplate restTemplate = new RestTemplate();
    HttpHeaders headers = new HttpHeaders();
    //一定要设置好ContentType为utf8否则会乱码
    MediaType type = MediaType.parseMediaType("application/json; charset=UTF-8");
    headers.setContentType(type);
    headers.add("Accept", MediaType.APPLICATION_JSON.toString());
    headers.add("Authentication", token);//设置自定义session header

    HttpEntity formEntity = new HttpEntity(json, headers);

    Map parameterMap = new HashMap<>();
    //entity = Header，uriVariables = Parameters;
    restTemplate.postForObject(autoDeployUrl, formEntity, String.class, parameterMap);
  }

  
  public static void test4(){
      JSonObject response = null;
      Map param = new HashMap<>();
      param.put("ming", "chyen");

      String json = "haha";
      try {
 response = RestUtil.post("http://127.0.0.1:8080/cloud-master/api/release/manages/detail", JSONObject.class,null,null,json);
      } catch (Exception e) {
 e.printStackTrace();
      }
      System.out.println(response);
  }
  
  public static void test(){
    RestTemplate restTemplate = new RestTemplate();

    Map parameterMap = new HashMap<>();
    restTemplate.getForObject("url", String.class,parameterMap);
    //factory.createRequest(uri, httpMethod)
  }
}

Util

public class RestUtil {
  private static RestTemplate restTemplate = new RestTemplate();

  
  public static  T get(String url, Class returnClassName, Map parameters){
    if (parameters == null) {
      return restTemplate.getForObject(url, returnClassName);
    }
    return restTemplate.getForObject(url, returnClassName, parameters);
  }

  
  public static  T post(String url,Class returnClassName,Map inputHeader,Map inputParameter,String jsonBody){
    //请求Header
    HttpHeaders httpHeaders = new HttpHeaders();
    //拼接Header
    if (inputHeader != null) {
      Set keys = inputHeader.keySet(); 
      for (Iterator i = keys.iterator(); i.hasNext();) { 
 String key = (String) i.next(); 
 httpHeaders.add(key, inputHeader.get(key).toString()); 
      } 
    }
    //设置请求的类型及编码
    MediaType type = MediaType.parseMediaType("application/json; charset=UTF-8");
    httpHeaders.setContentType(type);
    httpHeaders.add("Accept", "application/json");
    List acceptableMediaTypes = new ArrayList<>();
    acceptableMediaTypes.add(MediaType.ALL);
    httpHeaders.setAccept(acceptableMediaTypes);

    HttpEntity formEntity = new HttpEntity(jsonBody, httpHeaders);
    if (inputParameter==null) {
      return restTemplate.postForObject(url, formEntity, returnClassName);
    }
    return restTemplate.postForObject(url, formEntity, returnClassName, inputParameter);
  }
}
