Pass system property to spring boot

A library I need to use reads system property in the following way:

System.getProperty("library.system.property")

Is there any way to pass such a property to spring boot while starting the app or do I need to set it in the system?

Update 2020-01-08

For spring-boot 2.2.2.RELEASE while develop

mvn spring-boot:run -Dspring-boot.run.jvmArguments="-Dmy_system_properties=test1"

For spring-boot 1.5.x.RELEASE or below while develop

mvn spring-boot:run -Drun.jvmArguments="-Dmy_system_properties=test1"

For run as jar

java -Dmy_system_properties=test1 -jar service.jar

You can try with a runnable example, here https://www.surasint.com/spring-boot-pass-system-properties-in-command-line/

you can also do it like this:

public static void main(String[] args) {
    System.setProperty("key", "value");
    SpringApplication.run(MyApplication.class);
}

If you are using spring-boot maven plugin to execute the application, try (no line breaks)

mvn spring-boot:run -Drun.jvmArguments="-Xms2048m -Xmx4000m -XX:MaxPermSize=2048m 
-Dlibrary.system.property=value"

Refer maven plugin for additional details

You can pass it on the command line: 

java -Dlibrary.system.property=value -jar myapp.jar
