1. 建mould

cloud-gateway9527

2. 改pom

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>
        <groupId>com.atguigu.cloud</groupId>
        <artifactId>cloud2024</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <artifactId>cloud-gateway9527</artifactId>

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>
        <!--gateway-->

        <!--服务注册发现consul discovery,网关也要注册进服务注册中心统一管控-->

            <artifactId>spring-boot-starter-actuator</artifactId>

    </dependencies>

    <build>
        <plugins>
            <plugin>

            </plugin>
        </plugins>
    </build>

</project>

3. 写yml配置

server:
  port: 9527

spring:
  application:
    name: cloud-gateway #以微服务注册进consul或nacos服务列表内
  cloud:
    consul: #配置consul地址
      host: localhost
      port: 8500
      discovery:
        prefer-ip-address: true
        service-name: ${spring.application.name}

4. 主启动

package com.atguigu.cloud;

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

/**
 * @auther zzyy
 * @create 2023-11-20 12:38
 */
@SpringBootApplication
@EnableDiscoveryClient //服务注册和发现
public class Main9527
{
    public static void main(String[] args)
    {
        SpringApplication.run(Main9527.class,args);
    }
}

5. 启动
