从其他应用程序启动Spring Boot App

Question

I have a java application and a Spring Boot application. I want to MySpringBootApp.run() and MySpringBootApp.hereYouHaveSomeInfo() , so I want to call methods of the Spring Boot App but Spring Boot kind of processes my class and renames it, so I get a ClassNotFoundException in the other App.

Thanks for you help!

If I understand you correctly, you are building the executable version of the spring boot application.

This jar file cannot be used as a dependency.

You need to build the classical jar file without the dependencies and add this to your application's dependency list.

I suppose you build with maven . The target folder will contain two files:

• a yourapp-<version>.jar and
• a yourapp-<version>.jar.original which is substanially smaller.

The .jar File is not suitable for inclusion as a dependency. You need the .original file. I suggest, if you need both, that you setup a project creating the .original file as regular .jar target, without the spring-boot plugin. And you add another project, with the spring-boot plugin, that requires the "simple" .jar file as dependency and has the spring-boot plugin enabled.

Your second application will also list the "simple" jar file as a dependency, the fat jar can be delivered as usual.
