Eureka简单使用

1.环境准备

   1.JDK 17,Gradle 8.10.2,SpringBoot 3.0.2

2.Eureka-server

1.创建项目勾选所需的依赖

1.spring-boot-starter-security

2.spring-cloud-starter-netflix-eureka-server

3.spring-boot-starter-web

2.@EnableEurekaServer 注解启用服务注册

package com.gulimall.eurekaserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * @author yangfeifei
 */
@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {

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

}

3.禁用CSRF

package com.gulimall.eurekaserver.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.web.SecurityFilterChain;

/**
 * eureka-server
 *
 * @author yangfeifei
 * @date 2025/2/18 16:36
 * @description SecurityConfig
 */
@Configuration
public class SecurityConfig {

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
                 .csrf().disable()  // 关闭CSRF保护（Eureka客户端不支持CSRF）
                .authorizeHttpRequests(authorize -> authorize
                        .requestMatchers("/**").authenticated()  // 匹配所有路径需要认证
                )
                .httpBasic();
        return http.build();
    }
}

4.服务端配置（application.yml)

# port
server:
      port: 8000

# Spring Security
spring:
    application:
      name: eureka-server
    security:
      user:
        name: your_username
        password: your_password
eureka:
  client:
    register-with-eureka: true  # false不将自己注册到Eureka服务器
    fetch-registry: true        # false不从Eureka服务器拉取注册表信息
    serviceUrl:
      defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@localhost:${server.port}/eureka/ # 指定Eureka服务器地址

3.Eureka-client

1.创建项目勾选所需的依赖

1.spring-cloud-starter-netflix-eureka-client

2.spring-boot-starter-web

2.@EnableDiscoveryClient 注解启用客户端发现

package com.gulimall.eurekaclient;

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

/**
 * @author yangfeifei
 */
@EnableDiscoveryClient
@SpringBootApplication
public class EurekaClientApplication {

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

}

 3.客户端配置（application.yml)

# port
server:
      port: 8001

spring:
    application:
      name: eureka-client

# Eureka
eureka:
  client:
    service-url:
      defaultZone: http://your_username:your_password@localhost:8000/eureka/ # 指定Eureka服务器地址

4.访问
