使用Java解压目录中所有受密码保护的zip文件可以通过以下步骤实现:
- 导入所需的Java类库:import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
- 创建一个解压方法:public static void unzipPasswordProtectedFiles(String directoryPath, String password) throws IOException {
File directory = new File(directoryPath);
File[] zipFiles = directory.listFiles((dir, name) -> name.toLowerCase().endsWith(".zip"));
for (File zipFile : zipFiles) {
unzipPasswordProtectedFile(zipFile, password);
}
}
- 创建解压单个受密码保护的zip文件的方法:public static void unzipPasswordProtectedFile(File zipFile, String password) throws IOException {
byte[] buffer = new byte[1024];
try (ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream(zipFile))) {
ZipEntry zipEntry = zipInputStream.getNextEntry();
while (zipEntry != null) {
String entryName = zipEntry.getName();
File newFile = new File(zipFile.getParent(), entryName);
if (zipEntry.isDirectory()) {
newFile.mkdirs();
} else {
new File(newFile.getParent()).mkdirs();
try (FileOutputStream fileOutputStream = new FileOutputStream(newFile)) {
int length;
while ((length = zipInputStream.read(buffer)) > 0) {
fileOutputStream.write(buffer, 0, length);
}
}
}
zipEntry = zipInputStream.getNextEntry();
}
}
}
- 调用解压方法:public static void main(String[] args) {
String directoryPath = "目录路径";
String password = "密码";
try {
unzipPasswordProtectedFiles(directoryPath, password);
System.out.println("解压完成!");
} catch (IOException e) {
e.printStackTrace();
}
}
这样,使用Java就可以解压目录中所有受密码保护的zip文件了。
