SpringCloud-GateWay整合eureka实现网关转发

前言:学习springcloud时,教程使用的是zuul,搜了半天访问还是404,一气之下直接使用gateway(bushi,而且Netfilex也停止维护了

一.引入依赖

<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
            <!-- 版本自己加 -->
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
</dependencies>

二.配置gateway

1.application.yaml

server:
  port: 9527  #服务端口

spring:
  application:
    name: springcloud-gateway  #服务名
    # 开启 Gateway 服务注册中心服务发现
  cloud:
    gateway:
      discovery:
        locator:
          enabled: true

eureka:
  instance:
    instance-id: springcloud-zuul-9527
  client:
    service-url:
      defaultZone: http://localhost:7001/eureka/ 
      prefer-ip: true

2.启动类

package org.NNF.spring;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class GatewayApplication {
    public static void main(String[] args) {
        SpringApplication.run(GatewayApplication.class,args);
    }
}

三.注册中心,和服务省略了(偷个懒doge)

网关访问具体服务的格式: http://网关IP:端口/serviceId/**
