我编写了一个如下所示的小 Java 程序来使用提供的目录创建一个 zip 存档。
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
public class Demo {
public static void main(String[] args) {
FileOutputStream destinationZipOutputStream = null;
try {
destinationZipOutputStream = new FileOutputStream("/home/kasun/Downloads/sample/test/compress.zip");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
ZipOutputStream updateZipOutputStream = new ZipOutputStream(destinationZipOutputStream);
updateZipOutputStream.setLevel(ZipOutputStream.STORED);
File sourceFile = new File("/home/kasun/Downloads/sample/resources");
try {
zipFile(sourceFile, "parentdir", updateZipOutputStream);
updateZipOutputStream.close();
destinationZipOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
private static void zipFile(File fileToZip, String fileName, ZipOutputStream updateZipOutputStream) throws
IOException {
if (fileToZip.isHidden()) {
return;
}
if (fileToZip.isDirectory()) {
// Creating directories with in the zip file
if (fileName.endsWith("/")) {
updateZipOutputStream.putNextEntry(new ZipEntry(fileName));
updateZipOutputStream.closeEntry();
} else {
updateZipOutputStream.putNextEntry(new ZipEntry(fileName + "/"));
updateZipOutputStream.closeEntry();
}
File[] childFiles = fileToZip.listFiles();
if (childFiles == null) {
throw new IOException("IOException occurred when getting list of files of directory " +
fileToZip.toString());
}
for (File file : childFiles) {
zipFile(file, fileName + "/" + file.getName(), updateZipOutputStream);
}
} else {
// Creating files with in the zip file
try (FileInputStream sourceInputStream = new FileInputStream(fileToZip)) {
updateZipOutputStream.putNextEntry(new ZipEntry(fileName));
byte[] buffer = new byte[1024];
int length;
while ((length = sourceInputStream.read(buffer)) > 0) {
updateZipOutputStream.write(buffer, 0, length);
}
updateZipOutputStream.closeEntry();
}
}
}
}
归档创建中使用的/home/kasun/Downloads/sample/resources 目录包含以下层次结构
~/Downloads/sample/resources pwd
/home/kasun/Downloads/sample/resources
~/Downloads/sample/resources tree
.
├── sampledir
│ └── a
│ └── b
│ └── c
│ └── sample.jar
├── sampleFile1.txt
├── sampleFile2.txt
└── sampleFile3.yaml
4 directories, 4 files
以上代码正确创建了 zip 文件，可以通过在终端中执行以下命令来解压缩，
unzip -q /home/kasun/Downloads/sample/test/compress.zip
但是，从UI解压时出现如下错误
我在 Ubuntu 18.04 上使用 java 1.8.0_171
==== 根据评论中的要求，请找到 -v 输出如下，
✘ ~/Downloads/sample/test unzip -v compress.zip

最佳答案
我能够通过删除 zip 文件中的目录创建逻辑来解决问题。
请找到工作代码如下，
package zip.extraction.error;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
public class Demo {
public static void main(String[] args) {
FileOutputStream destinationZipOutputStream = null;
try {
destinationZipOutputStream = new FileOutputStream("/home/kasun/Downloads/sample/test/compress.zip");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
ZipOutputStream updateZipOutputStream = new ZipOutputStream(destinationZipOutputStream);
updateZipOutputStream.setLevel(ZipOutputStream.STORED);
File sourceFile = new File("/home/kasun/Downloads/sample/resources");
try {
zipFile(sourceFile, "parentdir", updateZipOutputStream);
updateZipOutputStream.close();
destinationZipOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
private static void zipFile(File fileToZip, String fileName, ZipOutputStream updateZipOutputStream) throws
IOException {
if (fileToZip.isHidden()) {
return;
}
if (fileToZip.isDirectory()) {
// Creating directories with in the zip file
/* if (fileName.endsWith("/")) {
updateZipOutputStream.putNextEntry(new ZipEntry(fileName));
updateZipOutputStream.closeEntry();
} else {
updateZi`pOutputStream.putNextEntry(new ZipEntry(fileName + "/"));
updateZipOutputStream.closeEntry();
}*/
File[] childFiles = fileToZip.listFiles();
if (childFiles == null) {
throw new IOException("IOException occurred when getting list of files of directory " +
fileToZip.toString());
}
for (File file : childFiles) {
zipFile(file, fileName + "/" + file.getName(), updateZipOutputStream);
}
} else {
// Creating files with in the zip file
try (FileInputStream sourceInputStream = new FileInputStream(fileToZip)) {
updateZipOutputStream.putNextEntry(new ZipEntry(fileName));
byte[] buffer = new byte[1024];
int length;
while ((length = sourceInputStream.read(buffer)) > 0) {
updateZipOutputStream.write(buffer, 0, length);
}
updateZipOutputStream.closeEntry();
}
}
}
}
unzip -v命令的输出如下，
~/Downloads/sample/test unzip -v compress.zip
Archive: compress.zip
