Question

我有一个示例Eureka服务器项目，在IntelliJ中运行时可以正常工作，或者使用＆＃34; mvn spring-boot：run＆＃34 ;.但是，当使用＆＃34; java -jar eureka-server-1.0-SNAPSHOT.jar＆＃34;直接运行超级jar时，我得到以下堆栈跟踪：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

这是POM文件：

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

所以我确实有一个spring-cloud-starter-eureka-server启动器依赖项，而且我在项目的任何地方都没有@EnableDiscoveryClient注释。

这是整个项目中唯一的.java文件：

server.port=8761
eureka.client.registerWithEureka: false
eureka.client.fetchRegistry: false
eureka.server.waitTimeInMsWhenSyncEmpty: 0

这是application.properties文件：

                            <ControlTemplate.Triggers>
                            <Trigger Property="IsExpanded" Value="True">
                                <Setter TargetName="Items" Property="Visibility" Value="Visible"/>
                                <Setter TargetName="ItemsRow" Property="Height" Value="0"/>
                            </Trigger>
                        </ControlTemplate.Triggers>

提前谢谢！

Eureka 将无法使用与您指定的球衣版本（它不适合我）。

使用http://start.spring.io生成初始项目。

这个pom.xml确实有用。

Spring Cloud Eureka：与maven和IDE一起使用，但不是超级jar
