解决eureka添加security权限验证导致服务无法注册到eureka上

1.在eureka项目application.yml中添加security配置

server:
      port: 8081     #默认端口8761
    spring:
      security:
        user:
          name: admin  # 配置登录的账号是user
          password: admin #配置登录的密码是password123
    eureka:
      client:
        register-with-eureka: false   #是否注册到其他的eureka中
        fetch-registry: false    #是否合并其他eureka上的数据（获取eureka注册信息）
        service-url:
          #defaultZone: http://localhost:${ server.port}/eureka #通信地址不可少
          defaultZone: http://admin:admin@localhost:8081/eureka

2.在eureka服务提供者项目中引入eureka注册路径

server:
      port: 8082
    spring:
      application:
        name: 服务提供者                                #服务提供者名称  英文字母建议使用小写
      devtools:
        restart:
          additional-paths:  src/main/java
          enabled: true                               #热部署生效
    eureka:
      client:
        serviceUrl:
          defaultZone: http://admin:admin@localhost:8081/eureka  #eureka服务地址
      instance:
        prefer-ip-address: true      #显示ip

3.此时启动服务提供者项目会报错

4.解决办法：  
在eureka项目中添加自定义security配置

@Configuration
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter { 
        /** * @Description: 高版本的丢弃了 * security: * basic: * enabled: true 配置，应该使用以下方式开启 * @Param: [http] * @Return: void */
        @Override
        protected void configure(HttpSecurity http) throws Exception { 
            // Configure HttpSecurity as needed (e.g. enable http basic).
            http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.NEVER);
            http.csrf().disable();
            //注意：为了可以使用 http://${user}:${password}@${host}:${port}/eureka/ 这种方式登录,所以必须是httpBasic,
            // 如果是form方式,不能使用url格式登录
            http.authorizeRequests().anyRequest().authenticated().and().httpBasic();
        }
    }
