【全栈之路】微服务课程7_Eureka安全策略

前言

Eureka本身不具备安全认证的能力，Spring Cloud使用Spring Security为Eureka Server进行了增强。

Eureka Server端

• pom.xml增加依赖

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

• application.yml增加配置

1. 配置中如果不设置这段内容，账号默认是user，密码是一个随机值，该值会在启动时打印出来。
2. 将Eureka Server中的 eureka.client.service-url.defaultZone 修改为为http://{user}:{password}@EUREKA_HOST:EUREKA_PORT/eureka/ 的形式。

spring:
  security:
    user:
      name: admin                # 配置登录的账号是admin
      password: 123456     # 配置登录的密码是123456

eureka:
  client:
    service-url:
      defaultZone: http://admin:123456@peer1:8761/eureka/, http://admin:123456@peer2:8762/eureka/

• 新增WebSecurityConfig.java

package com.dream.shop.security;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

/**
 * Spring Cloud Finchley及更高版本，必须添加如下代码，部分关闭掉Spring Security
 * 的CSRF保护功能，否则应用无法正常注册！
 * ref: http://cloud.spring.io/spring-cloud-netflix/single/spring-cloud-netflix.html#_securing_the_eureka_server
 */
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.csrf().ignoringAntMatchers("/eureka/**");
    super.configure(http);
  }
}

• 登陆测试

http://localhost:8761/login

Eureka Client端

eureka:
  client:
    serviceUrl:
       defaultZone: http://admin:123456@peer1:8761/eureka/,http://admin:123456@peer2:8761/eureka/

测试

http://localhost:8761

http://localhost:8762
