ZuulProxy 在 Spring Boot 应用程序中不起作用

Question

我创建了一个 Spring Boot 应用程序，它有一个微服务。现在我想直接从我在 eureka 服务器上注册的浏览器访问那个微服务。

ServicesInfoClient类是一个微服务，其配置文件是serviceInfo.yml。

ServiceInfoClient.java：

package com.myoldschool.manager.serviceClientInfo;

import com.myoldschool.manager.studentnames.StudentNameCountClient;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
@EnableDiscoveryClient
@RestController
public class ServicesInfoClient {

    public static void main(String[] args) {
        System.setProperty("spring.config.name", "serviceInfo");
        SpringApplication.run(StudentNameCountClient.class, args);
    }

    @GetMapping("/getInfo")
    public String getServiceEndPoints(){
        return "all endpoints";
    }

}

serviceInfo.yml：

# Discovery Server Access
spring:
  application:
    name: services-info

eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://localhost:1111/eureka/
    instance:
      hostname: localhost

# HTTP Server
server:
  port: 4444   # HTTP (Tomcat) port

MyZuulProxyClient.java：

package com.myoldschool.manager.zuulservice;

import com.myoldschool.manager.ManagerApplication;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@EnableZuulProxy
@EnableDiscoveryClient
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
public class MyZuulProxyClient {

    public static void main(String[] args) {
        System.setProperty("spring.config.name", "zuulService");
        SpringApplication.run(ManagerApplication.class, args);
    }
}

zuulService.yml:

# Configure this Discovery Server
spring:
  application:
    name: zuul-service

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://localhost:1111/eureka/
    instance:
      hostname: localhost

# HTTP Server
server:
  port: 5555   # HTTP (Tomcat) port

zuul:
  routes:
    services-info:
      path: /services-info/**
      serviceId: services-info

现在运行应用程序后，当我点击http://localhost:1111/services-info/getInfo 时，它给了我这个错误：

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

我见过这么多线程，但没有一个有效。所以请告诉我我在这里做错了什么。

我看不到你的 EurekaServer 微服务。您需要将 Eureka Server 创建为端口：1111。之后，你的微服务就可以注册它了。
