Java 文件 解压缩 示例

Java实现压缩文件的解压缩操作,缺点是压缩文件内不能含有文件名为中文的的文件,否则会出现如下错误:

Exception in thread "main" java.lang.IllegalArgumentException: MALFORMED
	at java.util.zip.ZipCoder.toString(Unknown Source)
	at java.util.zip.ZipInputStream.readLOC(Unknown Source)
	at java.util.zip.ZipInputStream.getNextEntry(Unknown Source)
	at com.javatest.techzero.gui.ZipFileDemo.main(ZipFileDemo.java:22)

代码:

package com.javatest.techzero.gui;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;
import java.util.zip.ZipInputStream;

public class ZipFileDemo {
	@SuppressWarnings("resource")
	public static void main(String args[]) throws Exception {
		File file = new File("d:" + File.separator + "test.zip");
		File outFile = null;
		ZipFile zipFile = new ZipFile(file);
		ZipInputStream zipInput = new ZipInputStream(new FileInputStream(file));
		ZipEntry entry = null;
		InputStream input = null;
		OutputStream out = null;
		while ((entry = zipInput.getNextEntry()) != null) {
			System.out.println("开始解压缩" + entry.getName() + "文件。。。");
			outFile = new File("d:" + File.separator + entry.getName());
			if (!outFile.getParentFile().exists()) {
				outFile.getParentFile().mkdir();
			}
			if (!outFile.exists()) {
				outFile.createNewFile();
			}
			input = zipFile.getInputStream(entry);
			out = new FileOutputStream(outFile);
			int temp = 0;
			while ((temp = input.read()) != -1) {
				//System.out.println(temp);
				out.write(temp);
			}
			input.close();
			out.close();
		}
		System.out.println("Done!");
	}
}
