19.2 Running as a packaged application
If you use the Spring Boot Maven or Gradle plugins to create an executable jar you can run your application using java -jar. For example:
$ java -jar target/myproject-0.0.1-SNAPSHOT.jar
It is also possible to run a packaged application with remote debugging support enabled. This allows you to attach a debugger to your packaged application:
$ java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n \
-jar target/myproject-0.0.1-SNAPSHOT.jar
The Spring Boot Maven plugin includes a run goal which can be used to quickly compile and run your application. Applications run in an exploded form just like in your IDE.
$ mvn spring-boot:run
You might also want to use the useful operating system environment variable:
$ export MAVEN_OPTS=-Xmx1024m -XX:MaxPermSize=128M -Djava.security.egd=file:/dev/./urandom
(The “egd” setting is to speed up Tomcat startup by giving it a faster source of entropy for session keys.)
