〖Linux〗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

    local wrapper_script=$1
    cat <<-'EOT' >$wrapper_script

}

wrapfile=wrap_$$.sh

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

echo -e "
output: $package_name
"

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～！
