ZuulProxy 在 Spring Boot 应用程序中不起作用

Question

I have created a spring boot application and it has one microservice. Now i want to directly access that microservice from browser which I have registered with eureka server.

Class ServicesInfoClient is one microservice and its config file is 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

Now after running the application when i hit http://localhost:1111/services-info/getInfo it gives me this error:

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).

I have seen so many threads but none of them is working. So please tell me what I am doing wrong here.

I can't see your EurekaServer microservice. You need to create Eureka Server as port:1111. After that, your microservices can register it.
