STS创建的EurekaServer无法启动

时间：2018-07-09 20:16:01

标签： java spring spring-boot spring-cloud netflix-eureka

我是Spring Cloud的新手，正在看一些我从STS创建EurekaServer并试图作为spring-boot应用程序运行的视频。

我从下面需要做些什么吗？

  1. 配置任何东西来运行Euraka服务器？
  2. 在运行Euraka服务器之前，我是否还需要启动其他一些服务？
  3. 在application.properties中的资源文件夹中添加任何属性吗？

到目前为止，我的application.properties为空，并且出现以下错误。

任何人都可以帮助识别我所缺少的吗？

2 个答案:

答案 0 :(得分：0)

  
      
  1. 是否配置了使Eureka服务器运行的任何内容？
    2.   

否，如果您仅包括STS启动程序项目中的eureka服务器依赖项，那么创建样本启动程序仅是“必需的”。

  
      
  1. 在运行Eureka服务器之前，我还需要启动其他一些服务吗？
    2.   

否，没有必要向eureka服务器注册任何服务。

  
      
  1. 在application.properties中的资源文件夹中添加任何属性吗？
    2.   

这有点复杂。从理论上讲，不需要，不需要添加任何属性，但是由于包含了eureka-server依赖性和@EnableEurekaServer，它将尝试向eureka服务器注册，这将引发运行时异常，但不会停止/终止您的应用程序。要解决此问题，您可以添加

eureka.client.fetch-registry=false
eureka.client.register-with-eureka=false

此外，如果您正在本地计算机上运行多个spring boot应用程序，则建议添加

server.port=<your port like 8080, 8081 etc>

针对您遇到的异常，我尝试按照您的建议执行确切的步骤，但是在启动该应用程序时没有任何异常。

这是我对可能造成的原因的猜测

  1. 您当时在同一端口上运行了另一个应用程序-即8080端口（默认端口）
  2. 在某些情况下，我已经在您的跟踪中看到了例外情况，其中某些应用程序被配置为在google cloud应用程序引擎中运行，不确定是否正在尝试这种方法。

我已经创建了一个样本香草尤里卡服务器项目，希望它能对您有所帮助 sample eureka server

答案 1 :(得分：0)

您可以尝试在yml文件中提供以下代码或使用相同的属性。除此之外，这一切对我来说都很不错。
