如何在没有tomcat的情况下启动jhipster微服务应用程序

Question

I have created a jhipster (v3.4.0) microservice app and wanted to deploy it on production but not on a tomcat instance. I've configure it not to require jhipster-registry nor jhipster-console for log forwarding. So what I want to achieve is to run it as a java app/jar.

Here are my logs from running it with dev profile:

• I removed all references of tomcat embedded from pom.xml, because of not need as of my project.

• I removed all references of Servlets/ HTTPServlet.

• I'm running it now with SpringApplication instead of ApplicationContext

Answer 1

after a closer look at your logs, I think IMHO that your app is trying to get the configuration for your app, ie is looking up for http://localhost:8888/myapp/default .

Under the port 8888 is running mostly the spring clod config service ( here is the documentation ). Since you don't want to run the registry service check how your microservice is configured, eg have a look at the boostrap-[profile].yml in the config folder of your app.
