1. 背景

项目组使用的 Spring Boot 比较老，是 1.5.4.RELEASE 。最近被检测出 Spring Eureka 未授权访问漏洞。

现状是浏览器直接访问 Eureka Server 可以直接进去，看到已经注册的服务信息。

2. 方法

2.1 Eureka Server 添加安全组件

Eureka Server 添加 pom 依赖：

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

2.2 Eureka Server 添加参数

spring.application.name:demo-eureka
server.port: 8088
eureka.instance.hostname=localhost
#禁用将自己作为客户端注册，禁用客户端注册行为
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
#eureka地址
eureka.client.service-url.defaultZone=http://${spring.security.user.name}:${spring.security.user.password}@${eureka.instance.hostname}:${server.port}/eureka
#eureka.client.service-url.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka
#关闭自我保护 --本地开发环境可以关闭，生产环境
eureka.server.enable-self-preservation = false
#清理节点时间
eureka.server.eviction-interval-timer-in-ms = 60000
spring.security.basic.enabled=true
spring.security.user.name=demo
spring.security.user.password=123abcd

2.3 重启 Eureka Server

重启 Eureka Server ，然后刷新访问页面，显示登录框：

在这里插入图片描述

输入配置的用户名和密码。

spring.security.user.name=demo
spring.security.user.password=123abcd

然后就报错了：Reason: Bad credentials。

奇怪，明明是按照配置文件里面输入的，怎么还会报用户名或密码错误呢。

查了一些资料，说跟 security 加密方法有关，整了半天搞不定。

2.4 Eureka Server 升级版本

实在没招了，只能怀疑用的框架版本太低，去重新整一个，eureka 就用了个服务发现，问题不大。

访问：https://start.spring.io/

把项目下载到本地，依赖已经加好了：

	<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-server</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>org.springframework.security</groupId><artifactId>spring-security-test</artifactId><scope>test</scope></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency></dependencies>

在启动类上加上注解：

package com.demo.cloudeurekaserver;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;@EnableEurekaServer
@SpringBootApplication
public class CloudEurekaServerApplication {public static void main(String[] args) {SpringApplication.run(CloudEurekaServerApplication.class, args);}}

再把 2.2 的参数加到 properties 文件中（最好换个 server.port），然后 run 启动类，访问 eureka ，输入用户名和密码，进去了：

2.5 Eureka Client 配置

eureka client 参数：

eureka.client.enabled=true
eureka.client.eureka-server-port=8089
eureka.client.service-url.defaultZone=http://demo:123abcd@localhost:8089/eureka/

启动 eureka client，报错：

刷新 eureka 页面，也没有服务信息，服务注册失败了。

这是因为从 Spring Boot 2.0 开始，默认情况下会启用CSRF保护，以防止CSRF攻击应用程序，导致服务注册失败。

2.6 Eureka Server 添加代码

修改 Eureka Server ：

package com.demo.cloudeurekaserver;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
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;@EnableEurekaServer
@SpringBootApplication
public class CloudEurekaServerApplication {public static void main(String[] args) {SpringApplication.run(CloudEurekaServerApplication.class, args);}/*** springboot 从 2.0 开始，默认情况下会启用CSRF保护* 需要关闭*/@EnableWebSecuritystatic class WebSecurityConfig extends WebSecurityConfigurerAdapter {@Overrideprotected void configure(HttpSecurity http) throws Exception {//方法1：关闭csrf
//			http.csrf().disable();//方法2：忽略/eureka/** 所有请求http.csrf().ignoringAntMatchers("/eureka/**");super.configure(http);}}
}

重启 Eureka Server 和 Eureka Client ，这次没有报错，刷新页面，重新登录后，看到注册的服务信息：

2.7 其他问题

在 Spring Security 5.7.0-M2 中，WebSecurityConfigurerAdapter 被弃用了，Spring 鼓励用户转向基于组件的安全配置。这意味着，现在应该使用基于组件的安全配置来配置 HttpSecurity，而不是继承 WebSecurityConfigurerAdapter。这种方式更加灵活，可以更好地支持 Spring Boot 2.x 和 Spring 5.x。
