启动Java项目脚本

启动Java项目脚本

前提：本例中是基于 java->jar与lib 依赖分离，且处于同级目录；如果不是，可以自己修改配置文件（nohup java -jar xxx.jar）

maven打包配置jar与lib依赖分离

使用示例

语法：sh start.sh [options] [jar-version] [ADD_PORT]

options：

• start：启动服务
• stop：停止服务
• restart：重启服务
• status：查看服务状态
• debug：开启远程debug控制

jar-version：Java项目jar包名称，无需输入.jar后缀

ADD_PORT：options 为 debug 调试模式时用，默认监听端口为 51135，可自定义

启动程序：sh start.sh start test-1.x.x

debug启动：sh start.sh debug test-1.x.x |
sh start.sh debug test-1.x.x 51235

重启程序：sh start.sh restart test-1.x.x

查看运行状态：sh start.sh status test-1.x.x

关闭程序：sh start.sh stop test-1.x.x

获取使用教程：sh start.sh -h

[root@demo demos]# ls
start.sh lib test-1.0.jar

[root@demo demos]# sh start.sh start test-1.0
Service test-1.0.jar is starting！pid=17827
.................Start success.................

[root@demo demos]# sh start.sh status test-1.0
Service test-1.0.jar is running. It's pid=17827

[root@demo demos]# sh start.sh restart test-1.0
.................Restarting.................
Service test-1.0.jar is starting！pid=19134
.................Start success.................
.................Restart success.................

[root@demo demos]# sh start.sh stop test-1.0
Service stop success！pid:19134 which has been killed forcibly!

start.sh脚本
