Launch shell script for Java application

For Java Applications (non-Web applications), after deployment, a startup script is often required to load some Third-party jar packs and start the application.

For Java applications, I generally prefer to write the directory structure of a program as follows:

myapp
　　　　 |----lib
　　　　 |----bin
　　　　　　　　　　　　 |----packages
　　　　　　　　　　　　　　 一些配置文件和属性文件
　　　　　　　　　　　　　　 一个startup.sh、或bat启动脚本

Where packages is the root package of the program. These include child packages and class files.

In the package, there is a MAIN.CALSS class, which serves as the entry point for the program.

Here is a general formulation:

startup.sh

#!/bin/sh
programdir="."
num=$#
temp=$CLASSPATH
#setting　libs　path
libs=../lib/*
append(){
　　　　　　　　　　　　　　　　 temp=$temp":"$1
}
for　file　in　$libs;　　　　do
　　　　　　　　　　　　　　　　 append　$file
done
export　CLASSPATH=$temp:.:../:$programdir
export　LANG=zh_CN
nohup　java　-classpath　$CLASSPATH　　　　packaages.xxx.yyy.Main　&

So, as long as the program is organized in the way above, the startup script needs to change the package path in front of main.

Nohup: There is a nohup before the last line in the previous script, which attaches the input and output of the program to the Nohup.out file in the current directory.

is to run the program as a background process and not shut down because the terminal is closed.
