问题描述

我正在学习 springboot 和微服务.我创建了 3 个服务，并且一切正常.现在我已经创建了发现服务器，使用 start.spring.io 通过添加Eureka Server"作为依赖项.

I am learning springboot and microservices. I have created 3 services and all are working fine. Now i have created discovery server, using start.spring.io by adding "Eureka Server" as dependency.

我的pom.xml如下:

My pom.xml is as follows:

我的主要课程如下:

    package io.springboot.microserices.discoveryserver;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
    @SpringBootApplication
    @EnableEurekaServer

public class DiscoveryServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(DiscoveryServerApplication.class, args);
    }

}

但是我无法运行该应用程序.如果我运行，我将低于异常.有人能帮我解决这个问题吗.

But i am unable to run the application. If i run, i am getting below exception. Could some one help me in resolving this issue.

16:07:02.761 [main] ERROR org.springframework.boot.SpringApplication - Application startup failed

推荐答案

Finchley 与 Spring Boot 1.x 不兼容，您必须使用 Boot 2.0.x.对于 Boot 2.1.x，您需要使用 Greenwich.

Finchley is not compatible with Spring Boot 1.x, You must use Boot 2.0.x. For Boot 2.1.x you need to use Greenwich.
