解决Java原生压缩组件不支持中文文件名乱码的问题

时间:2022-09-07 13:30:38

最近发现Java原生的Zip压缩组件在压缩过程中,不支持文件名的中文编码,会在压缩过程中把中文文件名变成乱码。Apache的ant包中的压缩组件修复了这个问题,如果你在使用压缩功能时需要支持中文文件名,建议你直接使用Apache的压缩组件来实现这个功能。

具体使用方法:

1.在你的pom文件中增加对Apache的ant工具包的dependency:

?
1
2
3
4
5
<dependency>
  <groupId>org.apache.ant</groupId>
  <artifactId>ant</artifactId>
  <version>1.9.3</version>
</dependency>

并在头部引用用到的类:

?
1
2
3
import org.apache.tools.zip.ZipEntry;
import org.apache.tools.zip.ZipFile;
import org.apache.tools.zip.ZipOutputStream;

2.压缩的方法实现,大家注意,本组件支持设置编码(setEncoding("GBK")方法),解决了中文编码的问题:

public static void compress(String srcPath , String dstPath) throws IOException{
    File srcFile = new File(srcPath);
    File dstFile = new File(dstPath);
    if (!srcFile.exists()) {
      throw new FileNotFoundException(srcPath + "does not exists");
    }
 
    FileOutputStream out = null;
    ZipOutputStream zipOut = null;
    try {
      out = new FileOutputStream(dstFile);
      zipOut = new ZipOutputStream(new BufferedOutputStream(out));
      zipOut.setEncoding("GBK");
      String baseDir = "";
      compress(srcFile, zipOut, baseDir);
    }
    catch (Throwable ex){
      throw new RuntimeException(ex);
    }
    finally {
      if(null != zipOut){
        zipOut.close();
        out = null;
      }
 
      if(null != out){
        out.close();
      }
    }
  }
 
 
private static void compress(File file, ZipOutputStream zipOut, String baseDir) throws IOException{
    if (file.isDirectory()) {
      compressDirectory(file, zipOut, baseDir);
    } else {
      compressFile(file, zipOut, baseDir);
    }
  }
 
  /** 压缩一个目录 */
  private static void compressDirectory(File dir, ZipOutputStream zipOut, String baseDir) throws IOException{
    File[] files = dir.listFiles();
    for (int i = 0; i < files.length; i++) {
      compress(files[i], zipOut, baseDir + dir.getName() + "/");
    }
  }
 
  /** 压缩一个文件 */
  private static void compressFile(File file, ZipOutputStream zipOut, String baseDir) throws IOException{
    if (!file.exists()){
      return;
    }
 
    BufferedInputStream bis = null;
    try {
      bis = new BufferedInputStream(new FileInputStream(file));
      ZipEntry entry = new ZipEntry(baseDir + file.getName());
      zipOut.putNextEntry(entry);
      int count;
      byte data[] = new byte[BUFFER];
      while ((count = bis.read(data, 0, BUFFER)) != -1) {
        zipOut.write(data, 0, count);
      }
 
    }finally {
      if(null != bis){
        bis.close();
      }
    }
  }

      String zipEntryName = entry.getName();
      InputStream in = null;
      OutputStream out = null;
      try{
        in = zip.getInputStream(entry);
        String outPath = (dstPath+"/"+zipEntryName).replaceAll("\\*", "/");;
        //判断路径是否存在,不存在则创建文件路径
        File file = new File(outPath.substring(0, outPath.lastIndexOf('/')));
        if(!file.exists()){
          file.mkdirs();
        }
        //判断文件全路径是否为文件夹,如果是上面已经上传,不需要解压
        if(new File(outPath).isDirectory()){
          continue;
        }
 
        out = new FileOutputStream(outPath);
        byte[] buf1 = new byte[1024];
        int len;
        while((len=in.read(buf1))>0){
          out.write(buf1,0,len);
        }
      }
      finally {
        if(null != in){
          in.close();
        }
 
        if(null != out){
          out.close();
        }
      }
    }
  }

以上代码经过测试,可以直接使用。
