Question

所以我开箱即用了一个jHipster微服务网关。我有jHipster 4.5.2。除了回答设置问题之外，我没有做任何事情（你可以在下面看到我的答案）。我指定它在localhost：8082上运行。我也安装了Tomcat 8.5.15，它可以工作;当我打开它时，我在localhost：8080看到服务器页面。

我尝试通过执行以下操作来运行网关：

/Users/jimstewart/apache-maven-3.3.9/bin/mvn -Pprod package
java -jar target/data-gateway-0.0.1-SNAPSHOT.war

当它尝试启动时，我会在早期收到以下警告：

Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/DataGateway/dev/master": Connection refused; nested exception is java.net.ConnectExc

但Tomcat服务器正在运行：当我转到localhost：8080页面就在那里。

有大量的样板，数百行，所以我不会全部复制它们。但在以下错误中不断重复

2017-06-03 22:48:58.671 ERROR 1271 --- [           main] c.n.d.s.t.d.RedirectingEurekaHttpClient  : Request execution error

2017-06-03 22:48:58.674  WARN 1271 --- [           main]

c.n.d.s.t.d.RetryableEurekaHttpClient    : Request execution failed with message: java.net.ConnectException: Connection refused

最终它只是在没有开始的情况下关闭。

我也尝试通过从NetBeans运行它来启动它。当我打开Tomcat时，它会退出，因为“无法启动Tomcat：端口8080已经在使用中”。所以，很好，在关闭Tomcat的情况下启动它，这样它就可以自动启动它。然后它将无法启动因为“连接被拒绝”。

此处显示错误：

Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/DataGateway/dev/master": Connection refused; nested exception is java.net.ConnectExc

这意味着你没有启动JHipster注册表。为此，您有两个解决方案：

1）使用Docker，只需启动：docker-compose -f src/main/docker/jhipster-registry.yml up -d

2）克隆项目https://github.com/jhipster/jhipster-registry，然后yarn install并启动注册表：./mvwn

然后，尝试在http://localhost:8761

登录JHipster注册表

PS：我不太了解你如何在这里使用Tomcat，因为你的网关已经使用了嵌入式Undertow，所以你不需要另一台服务器。
