ava zip解压 中文_java解压ZIP 解决中文乱码 （GBK和UTF-8）

在Java中解压ZIP文件时，如果文件名或内容包含中文字符，可能会出现乱码问题。解决这个问题可以参考以下步骤：

1. 使用ZipInputStream类读取ZIP文件，并使用ZipEntry类获取ZIP文件中的每个文件。

2. 如果ZIP文件的编码格式为GBK，则可以使用以下代码进行解压：

ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream(zipFile), Charset.forName("GBK"));
ZipEntry zipEntry;
while ((zipEntry = zipInputStream.getNextEntry()) != null) {
    String fileName = zipEntry.getName();
    fileName = new String(fileName.getBytes("GBK"), "UTF-8");
    if (zipEntry.isDirectory()) {
        File folder = new File(outputFolder, fileName);
        folder.mkdirs();
    } else {
        File file = new File(outputFolder, fileName);
        FileOutputStream fos = new FileOutputStream(file);
        byte[] buffer = new byte[1024];
        int len;
        while ((len = zipInputStream.read(buffer)) > 0) {
            fos.write(buffer, 0, len);
        }
        fos.close();
    }
}
zipInputStream.close();

3. 如果ZIP文件的编码格式为UTF-8，则可以使用以下代码进行解压：

ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream(zipFile), Charset.forName("UTF-8"));
ZipEntry zipEntry;
while ((zipEntry = zipInputStream.getNextEntry()) != null) {
    String fileName = zipEntry.getName();
    if (zipEntry.isDirectory()) {
        File folder = new File(outputFolder, fileName);
        folder.mkdirs();
    } else {
        File file = new File(outputFolder, fileName);
        FileOutputStream fos = new FileOutputStream(file);
        byte[] buffer = new byte[1024];
        int len;
        while ((len = zipInputStream.read(buffer)) > 0) {
            fos.write(buffer, 0, len);
        }
        fos.close();
    }
}
zipInputStream.close();

通过以上代码，可以解决中文乱码问题。
