Spring 调用rest http接口的两种方式RestTemplate和WebClient

第一种：spring的RestTemplate

　　     HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        //header
        headers.set("Authorization", "1172452ae5f144cda26790d2ad18118e");
        MultiValueMap params= new LinkedMultiValueMap<>();
        //参数
        params.add("","");
        params.add("","");
        HttpEntity> requestEntity = new HttpEntity<>(params, headers);
        ResponseEntity 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
