我正在尝试使用 Zuul 和 Consul 创建一个 Spring 云微服务应用程序。

我的项目中有 2 个组件：

  1. 使用 Zuul 的 api-gateway 微服务

  2. Hello world 微服务（一个简单的 hello world Rest Webservice）

这是API网关的代码：

 @SpringBootApplication
 @EnableZuulProxy
 @EnableDiscoveryClient
 public class ZuulApplication {

 public static void main(String[] args) {
    SpringApplication.run(ZuulApplication.class, args);
  }

 }

应用程序.yml

 zuul:
  routes:
    hello1:
     path: /hello1/**
     serviceId: microservice-example

logging:
  level:
   org.springframework: INFO
   com.netflix: DEBUG

引导程序.yml

spring:
  application:
    name: edge-server

 cloud:
   consul:
    config:
      enabled: true
      host: localhost
      port: 8500

这是hello微服务的代码：

 @SpringBootApplication
 @EnableConfigServer
 @EnableDiscoveryClient
 @RestController
 public class Application {

 @RequestMapping(value="/hello1",method = RequestMethod.GET)
 public String hello() {
    System.out.print("hello1");
    return "Hello1";
 }
 public static void main(String[] args) {
    new SpringApplicationBuilder(Application.class).web(true).run(args);
 }
}

bootstrap.yml：spring：应用程序：名称：微服务示例配置文件：活动：本机

 cloud:
  consul:
   config:
    enabled: true
    host: localhost
    port: 8500

但是，当我测试我的服务时，浏览器会显示以下消息：
