用groovy写一个文件copy的watch dog

很简单的功能，工作中需要，因为不够懒，每次都运行ant的target

 

后来开发web写js/html越来越多，根本不用编译的，再不写这样的工具。用动态语言都很容易实现

分享下

 

class DeployWatchDogTask extends TimerTask {
	String srcDir
	String distDir
	List extList = ['.js', '.css', '.html', '.tpl', '.ftl']

	def ant = new AntBuilder()

	public DeployWatchDogTask(String src, String dist){
		this.srcDir = src
		this.distDir = dist
	}

	private void copy(String pathRelative){
		String src = srcDir + pathRelative
		String dist = distDir + pathRelative

		ant.copy file: src, tofile: dist
	}

	private String getRelativePath(String str, pre){
		return str.substring(pre.size())
	}

	private boolean isExt(String name){
		int pos = name.lastIndexOf('.')
		return pos >= 0 && name.substring(pos) in extList
	}

	public void run(){
		def srcModifyTime = [:]
		def distModifyTime = [:]
		new File(srcDir).eachFileRecurse{
			if(it.isFile() && isExt(it.name))
				srcModifyTime[getRelativePath(it.absolutePath, srcDir)] = it.lastModified()
		}

		new File(distDir).eachFileRecurse{
			if(it.isFile() && isExt(it.name))
				distModifyTime[getRelativePath(it.absolutePath, distDir)] = it.lastModified()
		}

		srcModifyTime.each{k, v ->
			long l = distModifyTime[k]
			if(!l || l != v)
				copy(k)
		}
	}
}

def runTask = {src, dist, interval ->
	new Timer().schedule(new DeployWatchDogTask(src, dist), new Date(), interval);
}

String distPath = 'D:/ws/www'
runTask(new File('../').absolutePath, 
	new File(distPath).absolutePath, 1000 * 10)
