springboot后端兩個服務相互調用

@Autowired
private RestTemplate restTemplate;

1、post或get請求

try {　　
　　//添加請求頭
    HttpHeaders headers = new HttpHeaders();
    headers.add("key", "value");
　　//T需要傳遞的body參數內容的類

    HttpEntity<T> requestEntity = new HttpEntity<>(t, headers);
　　//get請求把postForEntity修改為getForEntity,也可以按照以下方式請求

　　//ResponseEntity<T> responseEntity = restTemplate.exchange(url, HttpMethod.GET, requestEntity, T.class);
　　//HttpStatus status = responseEntity.getStatusCode();

　　ResponseEntity<T> responseEntity = restTemplate.postForEntity(URL,requestEntity, T.class);

 if (responseEntity.getStatusCode().is2xxSuccessful()) {
 logger.info("請求成功");
 }
} catch (Exception e) {
 logger.error("請求失敗：", e);
}
