利用Wrapper把Java应用封装成NT Service

2019年06月19日 ⁄ 综合 ⁄ 共 8676字 ⁄ 字号小中大 ⁄ 评论关闭

在windows环境下，有些时候，我们需要让java程序以service的形式来运行，省去那个黑窗口，在或是当java程序关闭时要去做一点事情，这种场景下这个功能就显得非常的实用了。

如果是在unix环境下，选择的就多一些，比如自己编写一段shell ，或是利用apache daemon，在或是利用wrapper for unix版，都是非常的便利。

apache daemon可以参考：使用apache daemon让java程序在unix系统上以服务方式运行

下面我写个demo来看一下wrapper如何把java以NT Service的方式运行。

首先我们到：http://wrapper.tanukisoftware.com/doc/english/download.jsp 下载对应的 wrapper for windown版本到本地。

解压后会得到如下几个文件：

wrapper.conf

wrapper.jar

wrapper.exe

wrapper.dll

我当前的目录结构是：

c:/win32/

— wrapper.conf

— wrapper.exe

— wrapper.dll

— lib

— wrapper.jar

— hook .jar

— other.jar

— log

好，我们根据这个目录结构来编辑wrapper.conf，内容如下：

#********************************************************************
# Wrapper Properties
#********************************************************************
set.default.HOOK_TEST_HOME=.
set.default.HOOK_TEST_BASE=.
set.default.HOOK_TEST_CONF=%HOOK_TEST_HOME%
set.default.HOOK_TEST_DATA=%HOOK_TEST_HOME%/log
wrapper.working.dir=.
# Java Application
wrapper.java.command=java

# Java Main class.  This class must implement the WrapperListener interface
#  or guarantee that the WrapperManager class is initialized.  Helper
#  classes are provided to do this for you.  See the Integration section
#  of the documentation for details.
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperStartStopApp

# Java Classpath (include wrapper.jar)  Add class path elements as
#  needed starting from 1
wrapper.java.classpath.1=%HOOK_TEST_HOME%/lib/*.jar

wrapper.ping.timeout=0

# Java Library Path (location of Wrapper.DLL or libwrapper.so)
wrapper.java.library.path.1=%HOOK_TEST_HOME%

# Java Additional Parameters
#wrapper.java.additional.1=

# Initial Java Heap Size (in MB)
wrapper.java.initmemory=3

# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=64

# Application parameters.  Add parameters as needed starting from 1
# parameter.5 is  a flag which controls whether or not the Wrapper should
# wait for all non daemon threads to complete before exiting the JVM
wrapper.app.parameter.1=com.jason.hook.HookTest
wrapper.app.parameter.2=1
wrapper.app.parameter.3=start
wrapper.app.parameter.4=com.jason.hook.HookTest
wrapper.app.parameter.5=TRUE
wrapper.app.parameter.6=1
wrapper.app.parameter.7=stop


#********************************************************************
# Wrapper Logging Properties
#********************************************************************
# Format of output for the console.  (See docs for formats)
wrapper.console.format=PM

# Log Level for console output.  (See docs for log levels)
wrapper.console.loglevel=INFO

# Log file to use for wrapper output logging.
wrapper.logfile=%HOOK_TEST_DATA%/wrapper.log

# Format of output for the log file.  (See docs for formats)
wrapper.logfile.format=LPTM

# Log Level for log file output.  (See docs for log levels)
wrapper.logfile.loglevel=INFO

# Maximum size that the log file will be allowed to grow to before
#  the log is rolled. Size is specified in bytes.  The default value
#  of 0, disables log rolling.  May abbreviate with the 'k' (kb) or
#  'm' (mb) suffix.  For example: 10m = 10 megabytes.
wrapper.logfile.maxsize=0

# Maximum number of rolled log files which will be allowed before old
#  files are deleted.  The default value of 0 implies no limit.
wrapper.logfile.maxfiles=0

# Log Level for sys/event log output.  (See docs for log levels)
wrapper.syslog.loglevel=NONE

#********************************************************************
# Wrapper NT Service Properties
#********************************************************************
# WARNING - Do not modify any of these properties when an application
#  using this configuration file has been installed as a service.
#  Please uninstall the service before modifying this section.  The
#  service can then be reinstalled.

# Name of the service
wrapper.ntservice.name=HookTest

# Display name of the service
wrapper.ntservice.displayname=HookTest

# Description of the service
wrapper.ntservice.description=Hook Test

# Service dependencies.  Add dependencies as needed starting from 1
wrapper.ntservice.dependency.1=

# Mode in which the service is installed.  AUTO_START or DEMAND_START
wrapper.ntservice.starttype=AUTO_START

# Allow the service to interact with the desktop.
wrapper.ntservice.interactive=false

编辑InstallService.bat脚本安装NT Service，内容如下：

@echo off

Hook.jar的内容很少，就一个类，内容如下：

package com.jason.hook;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

/**

 */
public class HookTest {
	static ServerSocket server = null;
	volatile static boolean isRun = false; 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		
		if (args[0].equalsIgnoreCase("start")) {
			start();
		}else{
			stop();
		}
		
	}
	
	
	public static void stop(){
		isRun = false;
		System.out.println("Hook...");
		if (server != null) {
			try {
				System.out.println("Server.Hook.Close...");
				FileOutputStream out = new FileOutputStream(new File("c:\\Hook.txt"));
				out.write("Server.Hook.Close...".getBytes());
				out.flush();
				out.close();
				server.close();
				System.exit(0);
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
				System.exit(0);
			}
		}else{
			System.out.println("Server.Hook...server is null");
			System.exit(0);
		}
	}
	

	
	public static void start(){
		try {
			server = new ServerSocket(8000);
			isRun = true;
			System.out.println("Listener port 8000");
			while(isRun){
				try {
					if (server == null || server.isClosed()) {
						break;
					}
					Socket client = server.accept();
					System.out.println("有新的连接..."+client.toString());
					InputStream inputStream = client.getInputStream();
					BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
					String s = null;
					while((s = reader.readLine()) != null){
						if (s.trim().equalsIgnoreCase("exit")) {
							isRun = false;
							System.out.println("Server.exit...");
							if (server != null) {
								server.close();
							}
							if (reader != null) {
								reader.close();
							}
							break;
						}else{
							System.out.println("Server:"+s);
						}
					}
				} catch (Exception e) {
					// TODO: handle exception
					e.printStackTrace();
				}
			}
			System.out.println("start method: exit app");
			System.exit(0);
		} catch (IOException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		finally{
			if (server != null) {
				try {
					server.close();
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		}
	}
	

}

接下来，我们就可以运行InstallService.bat来安装NT Service，运行UninstallService.bat来卸载这个服务。

感兴趣的可以试试，很好用！
