Zuul网关无法转发请求至客户端服务的问题求助

我配置了一个Zuul网关服务器及单个客户端应用，但通过Zuul网关访问URL时，请求并未转发至客户端服务，而是返回404错误。以下是相关日志、配置信息及测试结果：

Zuul服务器配置（application.yml） #

server:
  port: 8080

zuul:
  routes:
    client-service:
      path: /asd/**
      #      url: http://localhost:8081/home
      url: http://localhost:8081/login

客户端服务配置 #

server:
  port: 8081


spring:
  application:
    name: client-service

客户端服务控制器 #

@RestController
@RequestMapping("/login")
public class LoginController {

    @GetMapping
    public String findAll() {
        return "simple login get method method";
    }
}

测试结果 #

• 直接访问客户端服务端点：

Endpoint : http://localhost:8081/login
Result : simple login get method method

• 通过网关访问端点：

Endpoint : http://localhost:8080/asd
Result : Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
