Spring Boot run command line and terminate

I have a large Spring Boot monolithic Web Application project. This application is packaged as an executable JAR and serves all kinds of JSON REST endpoints.

Now, I sometimes want to run a piece of Java code to process or import a large file, or clean up certain database tables from the command line.

What would be good way to do this with Spring Boot?

I first looked into CommandLineRunner interface but this seems to serve a completely different use case. This is executed always when running the Spring Boot application, followed by starting the main application.

I would like to have this functionality in the same application as the main web app for various reasons:

If you want to reuse the same jar, you could use a combination of Profiles and CommandLineRunners.

@Configuration
public class BatchConfig {

    @Bean
    @Profile("import")
    public CommandLineRunner import() {
        // ...
    } 

    @Bean
    @Profile("dbClean")
    public CommandLineRunner dbClean() {
        // ...
    } 

}

Then, when you run the jar, pass the desired profile as argument.

java -jar -Dspring.profiles.active=dbClean yourJar.jar

In this way, your command line runners are executed only when the profile matches.
