I want to start a jar file (Spring Boot app), with additional parameters.
It start normally when I start by shell command:
java -jar spring.boot.jar --parameter01="My Parameter Value 01" --parameter02="My Parameter Value 02"
Now, I want to pass all parameters into a bash shell (to start it as a service within /etc/init.d)
java -jar spring.boot.jar $1
($1 is equals value above >> --parameter01="My Parameter Value 01" --parameter02="My Parameter Value 02")
Then Spring app doesn't recognize the value "My Parameter Value 01", but only "My".
What should I do ? I tried to escape the space character and quote character, but nothing work.
A simple script to call your java -jar spring.boot.jar with a single parameter, let's call it /etc/init.d/run-spring-boot, be sure to chmod +x /etc/init.d/run-spring-boot before executing it:
#!/bin/bash
echo java -jar spring.boot.jar $1
java -jar spring.boot.jar $1
Invoke the script with a single input parameter of the entire string quoted and with escaped inner quotation marks:
/etc/init.d/run-spring-boot "--parameter01=\"My Parameter Value 01\" --parameter02=\"My Parameter Value 02\""
I think you could try if your system supports systemd:
Create a service file with a name you consider is appropriate for you in the /etc/systemd/system/ directory:
sudo vi /etc/systemd/system/spring-boot.service
[Unit]
Description=Spring Boot Service
StartLimitIntervalSec=0
After=syslog.target
[Service]
Type=simple
Restart=always
RestartSec=4
User=root
ExecStart=/bin/bash -c "/usr/bin/java -jar spring.boot.jar --parameter01='My Parameter Value 01' --parameter02='My Parameter Value 02'"
[Install]
WantedBy=multi-user.target
Next you have to reload systemd:
sudo systemctl daemon-reload
Next you can start it:
sudo systemctl start spring-boot
Get status:
systemctl status spring-boot
Stop it:
sudo systemctl stop spring-boot
Or add it to autostart with system booting:
sudo systemctl enable spring-boot
To troubleshot you could run the next in parallel terminal window to see the realtime changes:
sudo tail -f /var/log/syslog
