Java守护项目(三)
所涉及到技术点:
?1. Java调用命令行文件:ProcessBuilder类的使用
?2. Java注册为操作系统服务,可用apache Daemon的Procrun工具来发布
?3. 杀进程:
?? windows下可以用 WScript 脚本，如下:
??? Sub Kill_Process(ProcessName, CMD)
??? For Each ps In getobject("winmgmts:\\.\root\cimv2:win32_process").instances_
??? ??? if Ucase(ps.name)=Ucase(ProcessName) then
??? ??? ??? index = InStr(ps.CommandLine, CMD)
??? ??? ??? If (index > 0) Then
??? ??? ??? ??? ps.terminate
??? ??? ??? End if
??? ??? End If
??? next
?End Sub
Kill_Process "java.exe", "org.eclipse.virgo.osgi.launcher.Launcher"
?linux下的杀进程脚本:
?? kill_XXX() {
??? PID=`ps -ef | grep java | grep XXX | grep XXX.path.home | awk 'BEGIN {FS=" "}{print $2}'`
??? if [ "X$PID" != "X" ]; then
??????? kill -9 $PID
??????? if [[ $? == 0 ]]; then
??????????? echo XXX is killed. PID=$PID
??????? else
??????????? echo Kill failed
??????? fi
??? else
??????? echo XXX is not running
??? fi
}
kill_XXX
? 4.执行用户权限问题： 必须是管理员用户
? 5.由于是调用bat文件来拉起服务，假如bat执行需要花费很长时间的话，需要另起一个线程来检查是否启动成功了
