Spring Boot - 两个微服务之间的 Rest 模板

Question

Rest Template 用于创建使用 RESTful Web 服务的应用程序。我正在使用 exchange() 方法来使用所有 HTTP 方法的 Web 服务。

我正面临一些问题，但对方没有得到价值 它给了我错误或身份验证问题 有什么我可以在这里使用的方法以及如何使用

谢谢

@RestController
public class ConsumeWebService {
   @Autowired
   RestTemplate restTemplate;

   @RequestMapping(value = "/template/products")
   public String getProductList() {
      HttpHeaders headers = new HttpHeaders();
      headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
      HttpEntity <String> entity = new HttpEntity<String>(headers);

      return restTemplate.exchange("
         http://localhost:8080/products", HttpMethod.GET, entity, String.class).getBody();
   }
}

回复是这样的

{
    "timestamp": 1543478566866,
    "status": 401,
    "error": "Unauthorized",
    "message": "Unauthorized",
    "path": "/logoutInfo"
}

我遇到的错误

根据堆栈跟踪中的错误，您正在访问的资源似乎是安全的，您必须在访问资源时传递承载（身份验证）令牌，而您没有传递令牌来访问此处的资源。
