用Groovy实现解压一个压缩文件，并且找出解压后文件里面的以数字或者大写字母开头的.groovy文件

 

 

import java.util.regex.Pattern
import java.util.zip.ZipEntry
import java.util.zip.ZipFile

class ZipUtil {

	def static unZip(String path)throws IOException
	{
		def count = -1;
		def index = -1;
		def savepath = "";
		def flag = false;
		def file = null;
		def is = null;
		def fos = null;
		def bos = null;
		
		savepath = "ZIPFolder/";
		ZipFile zipFile = new ZipFile(path);
		Enumeration<?> entries = zipFile.entries();
			
		while(entries.hasMoreElements())
		{
			def buf = new byte[2048];
			ZipEntry entry = (ZipEntry)entries.nextElement();
			def filename = entry.getName();
			
			filename = savepath + filename;
			File file2=new File(filename.substring(0, filename.lastIndexOf("/")));
		
			if(!file2.exists()){
				file2.mkdirs();
			}
							
			if(!filename.endsWith("/")){
				
				file = new File(filename);
				file.createNewFile();
				is = zipFile.getInputStream(entry);
				fos = new FileOutputStream(file);
				bos = new BufferedOutputStream(fos, 2048);
				
				while((count = is.read(buf)) > -1)
				{
					bos.write(buf, 0, count );
				}
				
				bos.flush();
				
				fos.close();
				is.close();

			}
		}
			
		zipFile.close();
			
	}

	def static illegalList=[]
	
	static findIllegalGroovyFile(def filePath){
		
		
		def pattern = Pattern.compile('^([0-9]|[A-Z]).*\\.groovy');
		
		def file=new File(filePath);
		
		def list=file.list()
		
		list.each {
			it ->
			def f=new File(filePath+it)
			if(f.exists()&&!f.isFile()){
				findIllegalGroovyFile(f.getPath()+"/")
			}
			else{
				
					def matcher = pattern.matcher(it);
					if(matcher.find()){
						
						illegalList << f.getPath()
					}
				
			}
			
		}
		
	}
	
	static main(args) {
	
		unZip("ZIPFolder/ZIP.zip")//解压文件
		findIllegalGroovyFile("ZIPFolder/ZIP/")//找出符合题目要求的文件
		illegalList.each{
			it ->
			println it
		}
	}

}

最后输出结果：
