Java项目通过启动jar启动项目脚本

贴出一个项目启动脚本，内容如下：

#!/bin/bash
# Steps:
# Removing /app/sit/<app_name>
# unzip /app/sit/.candidates/<app_name>.zip to /app/sit/<app_name>/app
# cd to /app/sit/<app_name>/app, and run java -jar ${JAVA_OPTS} xxx.jar
#
# logs are stored in /app/sit/<app_name>/logs
# If you want to overwrite config files in the jar, move it to /app/sit/<app_name>/conf
#
# /app/sit
#     |── .candidates
#     │   └──xxx.zip (Jenkins build with `deploy=true` will place zips here)
#     └── <app_name>
#         ├── app
#         │   ├── <app_name>-<version>.jar
#         │   └── lib
#         │       ├── activemq-all-5.11.3.jar
#         │       ├── ...
#         │       └── utility-cache-redis-0.0.1-SNAPSHOT.jar
#         ├── conf
#         │   └── env-xxx.properties (optional)
#         └── logs
#             └── biz.log

之后通过./bootstrap.sh (start|stop|restart|deploy|status) 脚本启动服务了
