我有一個樣品尤里卡服務器項目，運行時無論是在的IntelliJ，或者用「MVN春季啓動：運行」工作正常。然而，直接與 「Java的罐子尤里卡服務器-1.0-SNAPSHOT.jar」 運行尤伯杯罐子的時候，我發現了以下堆棧跟蹤：春雲尤里卡：工作與Maven和IDE，但不作爲尤伯杯罐子

所以我有一個彈簧雲起動尤里卡服務器啓動的依賴，再加上我沒有@EnableDiscoveryClient標註在項目的任何地方。
這裏是整個項目唯一的.java文件：
@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication
{
public static void main(String[] args) {
SpringApplication.run(EurekaApplication.class, args);;
}
}
這裏是application.properties文件：
server.port=8761
eureka.client.registerWithEureka: false
eureka.client.fetchRegistry: false
eureka.server.waitTimeInMsWhenSyncEmpty: 0
預先感謝您！
你爲什麼使用陰影插件？春季啓動插件應該爲你做所有這些。 – spencergibb
