eureka启动出错求助

发布时间 2023-12-26 10:10:41作者: 林同学的博客

在任务管理器中相关进程关干净的条件下，eureka不知何原因，时而启动成功时而启动失败，有了解的吗？

前提：

1、eureka服务器端配置文件如下：

#服务端口
server:
  port: 8761
#服务名称
spring:
  application:
    name: eureka
#eureka地址
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
    register-with-eureka: false #自身 不再向eureka注册
    fetch-registry: false #启动时禁用client的注册

2、启动类有@EnableEurekaServer

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

3、springboot、springcloud版本

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.1.6</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>

<dependencyManagement>
        <dependencies>
            <!-- springcloud -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>2022.0.3</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
</dependencyManagement>

4、euraka版本

<dependency>
　　<groupId>org.springframework.cloud</groupId>
　　<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>

报错日志如下：

真的纳闷了，会是什么原因呢，我是时而可以启动时而启动失败，真迷！
