将Jar文件打包成Linux可执行文件

因为不想敲写 java -jar jarfile，而是想直接敲写  ./jarfile 就能够跑起程序。

function usage ()
{
cat <<- EOT

Usage :  $0 [options] -p package -s script file1 file2 file3 ..

Options:
-h|help       Display this message
-p|package    The output package name
-j|jar file   The jar file

EOT
}    # ----------  end of function usage  ----------

#--------------------------------------------------
#  Handle command line arguments

while getopts ":hp:j:" opt
do
case $opt in

h|help    ) usage; exit 0   ;;
p|package ) package_name=$OPTARG ;;
j|jar     ) jar_file=$OPTARG ;;
\?        ) echo -e "\n  Option does not exist : $OPTARG\n"
usage; exit 1   ;;

esac    # --- end of case ---
done
shift $(($OPTIND-1))

if [[ -z $package_name ]]; then
echo "package_name can't not be empty"
usage
exit
fi

if [[ -z $jar_file ]]; then
echo "jar_file can't not be empty"
usage
exit
fi

generate_wrapper_script(){
local wrapper_script=$1
cat <<-'EOT' >$wrapper_script
#!/bin/sh
java -jar $0 "$@"
if [ $? -ne 0 ]; then
echo "run jar file failed."
exit 1
fi
exit 0
#__SCRIPTEND__
EOT
}

wrapfile=wrap_$$.sh

echo -e "start packing ..\n"
generate_wrapper_script $wrapfile
cat $wrapfile $jar_file > $package_name
chmod +x $package_name

echo -e "\noutput: $package_name\n"

rm -f $wrapfile

保存到 jar_wrapper.sh，使用方法举例：

./jar_wrapper.sh -p /tmp/aaa -j /tmp/test_demo1.jar

然后，chmod +x /tmp/aaa && /tmp/aaa 就能够跑起程序来了！
