RestTemplate调用

一、get请求

public class TestController{
    @Autowired
    RestTemplate restTemplate;

    public void getlist(String a,String b) {
       ResponseEntity<ResultVO<List<TClNew>>> result = restTemplate.exchange("http://192.168.1.1/server/getlist/{a}/{b}", HttpMethod.GET, null,
                new ParameterizedTypeReference<ResultVO<List<test>>>() {
                }, a, b);
     }
}　　

二、get请求

public class TestController{
    @Autowired
    RestTemplate restTemplate;

       public ResultVO<String> getlist(String a,String b) {
           return restTemplate.getForObject("http://192.168.1.1/server/getlist/{a}/{b}", ResultVO.class, a,  b);
    }
}　　

　　

三、post请求

public class TestController{
    @Autowired
    RestTemplate restTemplate;

　　public void post(){
　　　HttpHeaders headers = new HttpHeaders();
　　　Map<String, Object> map = new HashMap<>();
　　  map.put("aaa", "qqqq");
　　　　headers.setContentType(MediaType.MULTIPART_FORM_DATA);
　　　　HttpEntity<MultiValueMap<String, Object>> httpEntity = new HttpEntity<>(map, headers);
　　　　ResponseEntity<ResultVO<String>> response = restTemplate.exchange(url, HttpMethod.POST, httpEntity,
　　　　new ParameterizedTypeReference<ResultVO<String>>() {
　　　　});

　　}

} 

　四、post请求

public class TestController{
    @Autowired
    RestTemplate restTemplate;

    public ResultVO<String> getlist(String a,String b) {
      List<TestEntity> aaa = new ArrayList<>();
      return restTemplate.postForObject("http://192.168.1.1/server/post", aaa, ResultVO.class);

　　}

}
