文件压缩

[wildayfd]

为什么这段压缩文件的代码不能把文件压缩成系统自带的zip格式

public static void zip() throws Exception{
		
		FileInputStream file = new FileInputStream("D:\\EDC_FPT\\test.txt");
		// 压缩文件 ,在这里调用压缩文件方法
		// 定义压缩文件的名称
		// 定义压缩输出流
		ZipOutputStream zipOut = new ZipOutputStream(new FileOutputStream(new File("D:\\EDC_FPT\\test.zip")));
		//实例化压缩输出流,并制定压缩文件的输出路径 
		zipOut.putNextEntry(new ZipEntry("D:\\EDC_FPT\\test.txt"));

		int temp = 1;
		while((temp = file.read()) != -1) {
			zipOut.write(temp);
		}
		zipOut.close();
	}

报什么错？应该没有问题。

给你个正确的代码吧~我正常使用的方法

File file = null;
		File parent = null;
		ZipFile zipFile = null;
		BufferedInputStream bis = null;
		FileOutputStream fos = null;
		BufferedOutputStream bos = null;
		try {
			zipFile = new ZipFile(fileName);
			Enumeration<?> emu = zipFile.entries();
			while (emu.hasMoreElements()) {
				ZipEntry entry = (ZipEntry) emu.nextElement();
				if (entry.isDirectory()) {
					new File(targetPath + "/" + entry.getName()).mkdirs();
					continue;
				}
				bis = new BufferedInputStream(zipFile.getInputStream(entry));
				file = new File(targetPath + "/" + entry.getName());
				parent = file.getParentFile();
				if (parent != null && (!parent.exists()))
					parent.mkdirs();
				fos = new FileOutputStream(file);
				bos = new BufferedOutputStream(fos, BUFFER);
				int count;
				byte data[] = new byte[BUFFER];
				while ((count = bis.read(data, 0, BUFFER)) != -1) {
					bos.write(data, 0, count);
				}
				bos.flush();
			}
			new File(fileName).delete();
		} catch (Exception e) {
			logger.error("===method : unzip ERROR ===" + e.getMessage());
		} finally {
			file = null;
			parent = null;
			if (bos != null) {
				try {
					bos.close();
				} catch (IOException e) {
					logger.error("===method : unzip BufferedOutputStream close ERROR ===" + e.getMessage());
				}
			}
			if (fos != null) {
				try {
					fos.close();
				} catch (IOException e) {
					logger.error("===method : unzip FileOutputStream close ERROR ===" + e.getMessage());
				}
			}
			if (bis != null) {
				try {
					bis.close();
				} catch (IOException e) {
					logger.error("===method : unzip BufferedInputStream close ERROR ===" + e.getMessage());
				}
			}
			if (zipFile != null) {
				try {
					zipFile.close();
				} catch (IOException e) {
					logger.error("===method : unzip ZipFile close ERROR ===" + e.getMessage());
				}
			}
		}
