Spring cloud SpringCloud读取超时

我想完成spring cloud分布式网站建设，但我无法完成Eureka客户端到Euerka服务器的注册。我有一个关于春云的问题。我启动了三个Eureka群集服务，然后启动了一个Eureka客户端。在其中一个Eureka服务器中引发读取超时异常

这是我的Eureka客户的创业课程

@SpringBootApplication
@EnableEurekaClient     
public class DeptProvider8001_App {
    public static void main(String[] args) {
        SpringApplication.run(DeptProvider8001_App.class, args);
    }
}

@SpringBootApplication
@EnableEurekaServer     
public class EurekaServer7001_App {
    public static void main(String[] args) {
        SpringApplication.run(EurekaServer7001_App.class, args);
    }
}

这是我的Eureka服务器的启动类

@SpringBootApplication
@EnableEurekaClient     
public class DeptProvider8001_App {
    public static void main(String[] args) {
        SpringApplication.run(DeptProvider8001_App.class, args);
    }
}

@SpringBootApplication
@EnableEurekaServer     
public class EurekaServer7001_App {
    public static void main(String[] args) {
        SpringApplication.run(EurekaServer7001_App.class, args);
    }
}

这些是我的eureka服务器应用程序.xml

eureka:
  #server:
    #enable-self-preservation: false    
  instance:
     hostname: eureka7001.com      
  client:
    register-with-eureka: false
