第一种:spring的RestTemplate
HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_JSON); //header headers.set("Authorization", "1172452ae5f144cda26790d2ad18118e"); MultiValueMap<String, String> params= new LinkedMultiValueMap<>(); //参数 params.add("",""); params.add("",""); HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<>(params, headers); ResponseEntity<String> response = restTemplate.exchange("http://localhost:9000/supplywater/workSheet/getPageGroup", HttpMethod.GET, requestEntity, String.class); String sttr = response.getBody();
第二种:Spring WebFlux 5.0版本开始提供的一个非阻塞的基于响应式编程的进行Http请求的客户端工具WebClient
Flux<Map> resp = WebClient.create("http://localhost:9000") .get() .uri("/supplywater/workSheet/getPageGroup") .header("Authorization", "a42529f1532d4f9a9aac9fc080198c24") .retrieve() .bodyToFlux(Map.class); List<Map> block = resp.collectList().block(); System.err.println(block);
