Script example for starting and stopping spring boot projects in Linux

There are three ways to start a springboot project:

1. Run the main method program

2. Use the command mvn spring-boot:run to run on the command line

3. After using mvn packpage to package the jar file, run it using the java -jar yourapp.jar command line

Generally, we often use the first two running modes when developing, and the third mode when deploying and implementing. Below we will focus on downloading the instructions and scripts for running and stopping the springboot project in the Linux environment:

1. Instructions

nohup does not hang up the run command

Generally, you can use it directly in Linux:

java -jar yourapp.jar

To start the program, but once the process is terminated, the program will immediately hang up, so in this case, we have to use nohup

nohup java -jar yourapp.jar > yourapp.out 2>&1 &

But the biggest problem is that it is inconvenient to manage. what to do?

Second, write a shell script

1. start.sh

#!/bin/bash
nohup java -jar yourapp.jar -Xms256m -Xmx1024m > yourapp.out 2>&1 &

2. stop.sh

#!/bin/bash
PID=$(ps -ef | grep yourapp.jar | grep -v grep | awk '{ print $2 }')
if [ ${PID} ]; 
then
 echo 'Application is stpping...'
 echo kill $PID DONE
 kill $PID
else
 echo 'Application is already stopped...'
fi

3. Integrate the start and stop scripts and write run.sh

#!/bin/bash
echo 'Application is stpping...'
source stop.sh
echo 'Application is running...'
source start.sh
