运用JDK中 ZipOutputStream类实现文件的压缩功能
一个样例代码：
import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.util.zip.ZipEntry;import java.util.zip.ZipOutputStream;public class ZipOutputStreamExample {public static void main(String[] args) {byte[] buffer = new byte[1024];try {FileOutputStream fos = new FileOutputStream("log.zip");ZipOutputStream zos = new ZipOutputStream(fos);ZipEntry ze = new ZipEntry("weblog-20130710.log");zos.putNextEntry(ze);FileInputStream in = new FileInputStream("weblog.log");//要压缩的文本文件weblog.logint len;while ((len = in.read(buffer)) > 0) {zos.write(buffer, 0, len);}in.close();zos.closeEntry();zos.close();System.out.println("end");} catch (IOException ex) {ex.printStackTrace();}}}
