1 为Eureka Server配置HttpBasic验证
为了保证服务的安全性，我们为EurekaServer配置HttpBasic验证，只有知道用户名和密码的服务才能注册到Eureka Server。接下来我们基于之前的项目代码，来改造配置一下这部分相关内容。
在项目中引入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>在Eureka Server配置文件中加入用户名和密码相关配置
spring:
security:
user:
name: username
password: password访问Eureka Server UI
输入用户名和密码，可以登录
2 配置Eureka Client注册服务
修改Service-Provider服务的配置文件，在地址前加入用户名和密码，启动服务。
eureka:
client:
serviceUrl:
defaultZone: http://username:password@eureka-server-peer1:8100/eureka 服务报403的错误
Request execution failure with status code 403; retrying on another server if available
查看官方文档，发现下面一段话
By default when Spring Security is on the classpath it will require that a valid CSRF token be sent with every request to the app. Eureka clients will not generally possess a valid cross site request forgery (CSRF) token you will need to disable this requirement for the /eureka/** endpoints大概意思就是我们的Eureka Server加入了spring-boot-starter-security依赖之后，默认情况下，所有发送给Eureka Server的请求都必须带上CSRF Token，那么我们关闭这个验证就可以了，加入WebSecurityConfig，关闭此项验证。
package org.dothwinds.eurekaserver;
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.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@EnableWebSecurity
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.csrf().disable();
super.configure(httpSecurity);
}
}
然后启动服务，发现没有报错，进入Eureka Server UI查看服务已经注册成功了：）
