Question

使用CLI使微服务的多个实例在不同端口上侦听的最佳方法/命令是什么？

我试图通过从命令行运行Spring Boot应用程序来运行一个微服务的多个实例。当我从IDE运行一个微服务时，我在控制台上获得以下输出（显示了要向Eureka注册的SBA实例< / p>

Setting initial instance status as: STARTING

Registering application XX-PRODUCER with eureka with status UP

现在，我一直在使用标准的-Dserver.port选项以不同的端口号运行SBA，以便使n个SBA实例正常工作。但是，从命令行启动的实例似乎并未向Eureka注册自己，这与我在更改application.properties文件＃server.port属性后从IDE运行的实例不同。

D:\x\x>java -jar -Dserver.port=7001 xx-0.1.0.jar

我在运行jar时也尝试添加Eureka端口属性作为选项。

D:\x\x>java -jar -Dserver.port=7001
    -Deureka.client.serviceUrl.defaultZone=http://localhost:5000/eureka xx-0.1.0.jar

但是两次，在Eureka上注册的微服务实例的数量仅为1（一个实例是从STS IDE运行的）

D:\x\x>java -jar -Dserver.port=7001
-Deureka.client.serviceUrl.defaultZone=http://localhost:5000/eureka xx-0.1.0.jar

从命令行而不是IDE运行jar时，微服务未向Eureka注册
