Is there a standard way to customize the deploy path in Spring Boot?

Question

I'm exploring the possibilities of Spring Boot right now, and I'm at a slight impasse. I want to be able to run two Spring Boot applications at once, both on the same server, but at different paths (one deploys on /, the other deploys at /another-path).

Because this is an embedded Tomcat instance running within Spring Boot, there's no configuration files available for me to change.

Is there a standard way to do this? Is it possible?

Answer 1

Spring Boot comes with some pre-built property support. If you create an application.properties file, you can include:

server.port=<another port>
server.address=<another IP address>
server.sessionTimeout=<another timeout setting>
server.contextPath=/your-other-path

This can be in application.properties adjacent to your runnable JAR, embedded inside the JAR file, or simply applied as a -Dserver.contextPath=/your-alt-path with the java command. These are cascading, meaning you can embed one set of defaults inside the JAR, override with a local application.properties file, and then finally override application.properties with the -D options.

Answer 2

As it uses an embedded tomcat you should be able to add a /META-INF/context.xml to each application which specifies the path (at least this should work for a normal tomcat).

That works for our normal embedded tomcat stuff, so I would expect it to work for Spring Boot as well.
