Eureka添加安全验证的两种方式其一：使用Spring Security(2022最新版本)

1. 使用Spring Security

已有做好的demo，大家可以自取,链接：https://github.com/MingGH/demo-eureka-server-auth

这里代码使用的依赖版本如下

spring-boot-starter-parent	3.0.1
spring-cloud.version	2022.0.0
java.version	17

开始我们的步骤

1.1 pom.xml中添加spring security的依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

1.2 yaml配置中添加登录和接口请求需要的账号密码

server:
  port: 5005

spring:
  application:
    name: demo-eureka-server-auth
  security:
    user:
      name: develop # 账号
      password: develop # 密码
eureka:
  instance:
    hostname: localhost
    appname: ${spring.application.name}
  server:
    enable-self-preservation: true
    eviction-interval-timer-in-ms: 4000
  client:
    registerWithEureka: true # 这里我设置为true是因为把当前项目也注册到注册中心，就省了新建一个client项目
    fetchRegistry: false
    service-url:
      defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@${eureka.instance.hostname}:${server.port}/eureka #这里是有更改的，对应的内容是：http://develop:develop@localhost:5005/eureka
  environment: dev

在上述配置中需要注意的几个配置，

spring.security.user账号密码
eureka.client.registerWithEureka=true 这里我设置为true是因为把当前项目也注册到注册中心，就省了新建一个client项目
eureka.client.service-url.defaultZone=http://${spring.security.user.name}:${spring.security.user.password}@${eureka.instance.hostname}:${server.port}/eureka 对defaultZone [进行特殊配置是因为spring.security](http://进行特殊配置是因为spring.security) 需要账号密码才能授权请求到对应的接口

1.3 Spring Security关闭csrf

新建一个WebSecurityConfig, 注入spring容器中

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.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.web.SecurityFilterChain;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .authorizeRequests()
                .anyRequest()
                .authenticated()
                .and()
                .httpBasic();
        return http.build();
    }
}

最后别忘了在启动类上加上注解：@EnableEurekaServer
