Specify main class Spring-Boot command line

Question

I use maven plugin to set the main class like this :

org.springframework.boot
spring-boot-maven-p         


        

Answer 1

There's a launcher for that in Spring Boot already. You need to build the jar with that as the Main-Class (by setting the layout in the build config).

Answer 2

Executing from Windows PowerShell I needed this format (with the quotes):

java -cp .\myjarfile.jar -D"loader.main=com.app.etc.FullyQualifiedMainClass" org.springframework.boot.loader.PropertiesLauncher

To clarify the accepted answer: You can directly modify the loader.main property in the jar's META-INF/MANIFEST.MF file, if you're ok with a more static solution.

Answer 3

Following command will do the trick:

java -cp my-app.jar -Dloader.main=myApplicationClass org.springframework.boot.loader.PropertiesLauncher
