Java compressed file garbled problem

Use java to package files to generate compressed files. There are two places where garbled characters will appear:

1. The Chinese garbled content problem: modify the source code of sun. Use the open source class libraries org.apache.tools.zip.ZipOutputStream and org.apache.tools.zip.ZipEntry. These two classes are available in ant.jar and can be downloaded and used.

2. The Chinese garbled problem of compressed file comments: zos.setComment("Chinese test"); Find the problem by using the setting encoding method (zos.setEncoding("gbk");) and test the encoding of the project The mode is gbk, and the default encoding is utf-8.

org.apache.tools.zip.ZipOutputStream uses the encoding method of the project by default, which can be solved by changing it to gbk through the setEncoding method.

java compressed file code:

package com.compress; import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.DataInputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import org.apache.tools.zip.ZipEntry; import org.apache.tools.zip.ZipOutputStream; public class CompressEncodingTest { /** * @param args * @throws Exception */ public static void main(String[] args) throws Exception { File f = new File("中文测试.txt"); ZipOutputStream zos = new ZipOutputStream(new BufferedOutputStream( new FileOutputStream("zipTest.zip"), 1024)); zos.putNextEntry(new ZipEntry("中国人.txt")); DataInputStream dis = new DataInputStream(new BufferedInputStream( new FileInputStream(f))); zos.putNextEntry(new ZipEntry(f.getName())); int c; while ((c = dis.read()) != -1) { zos.write(c); } zos.setEncoding("gbk"); zos.setComment("中文测试"); zos.closeEntry(); zos.close(); } }
