Editor to share with you how to make springboot's jar package start in service mode, I believe most people don't know much about it, so share this article for your reference. I hope you can learn a lot after reading this article. Let's learn about it together.

Springboot's jar package launches the scene in service mode

The typed jar package can definitely be started with java-jar. This approach is inherently simple, but not friendly to operation and maintenance.

So the transformation is required, and it is hoped that it can be started with the service command.

Process

It's technically achievable.

Pom.xml configuration

There are 2 configuration points in pom.xml:

Custom-app org.springframework.boot spring-boot-maven-plugin true

Note: finalName should be unique and do not have a version number such as .1.1 snapshot.

Maven, Authorization, Startup

Package first, and then execute the following script:

# authorize chmod 755 custom-app; # start. / custom-app.jar

If it can be executed, it means that the maven configuration is in effect and the jar package becomes the execution file.

Note: look at the jar package and find that the shell script is added to the first 2300 lines, which is what true generates.

Also: java-jar is still available and will not be affected.

Establish a soft connection and start it with the service command

The command is as follows:

# establish a soft connection ln-s / data/custom-app.jar / etc/init.d/custom-app# and then start service custom-app start with the service command

It is found that the log is not output, so how is it started? How to read the log?

# here you can see the launched log / var/log/custom-app.log# to view the pid. The template is: / var/run//.pid/var/run/custom-app/custom-app.pidsystemctl configuration

Because it is not useful, for the time being.

The use of systemctl configuration is also found in the bottom spring document.
