Since Spring Boot 2.2.0.RELEASE spring-boot-maven-plugin
mvn spring-boot:run -Drun.profiles=prod
create two java process (see https://github.com/spring-projects/spring-boot/issues/17766). In my case:

It is too verbose and for Windows could cause of "error CreateProcess error=206, The filename or extension is too long" (see Jhipster 5.7 microservice failed to start on windows with error CreateProcess error=206, The filename or extension is too long).
What is the best way to fix it (exclude return to previous version:)?
回答1:
Apparently, forking is enabled by default since Spring Boot 2.2.
Disable it again might help.
Add -Dspring-boot.run.fork=false to your maven command or configure it in your pom.xml:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<fork>false</fork>
</configuration>
</plugin>
