Java中Zip文件的路径处理

在Java中，可以使用java.util.zip包来处理ZIP文件。以下是一些关于Java中ZIP文件路径处理的常见操作：

1. 创建ZIP文件：

import java.io.*;
import java.util.zip.*;

public class CreateZipFile {
    public static void main(String[] args) {
        String zipFileName = "example.zip";
        String[] filesToAdd = {"file1.txt", "file2.txt", "file3.txt"};

        try (FileOutputStream fos = new FileOutputStream(zipFileName);
             ZipOutputStream zos = new ZipOutputStream(fos)) {

            for (String fileName : filesToAdd) {
                File file = new File(fileName);
                ZipEntry zipEntry = new ZipEntry(file.getName());
                zos.putNextEntry(zipEntry);

                try (FileInputStream fis = new FileInputStream(file)) {
                    byte[] buffer = new byte[1024];
                    int bytesRead;
                    while ((bytesRead = fis.read(buffer)) != -1) {
                        zos.write(buffer, 0, bytesRead);
                    }
                }

                zos.closeEntry();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

2. 从ZIP文件中提取文件：

import java.io.*;
import java.util.zip.*;

public class ExtractZipFile {
    public static void main(String[] args) {
        String zipFileName = "example.zip";
        String destDirectory = "extracted_files";

        File destDir = new File(destDirectory);
        if (!destDir.exists()) {
            destDir.mkdir();
        }

        try (ZipInputStream zis = new ZipInputStream(new FileInputStream(zipFileName))) {
            ZipEntry zipEntry;
            while ((zipEntry = zis.getNextEntry()) != null) {
                String fileName = zipEntry.getName();
                File newFile = new File(destDirectory + File.separator + fileName);

                if (!zipEntry.isDirectory()) {
                    extractFile(zis, newFile);
                } else {
                    File dir = new File(newFile.getParent());
                    if (!dir.exists()) {
                        dir.mkdir();
                    }
                }
            }
            zis.closeEntry();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private static void extractFile(ZipInputStream zis, File newFile) throws IOException {
        try (FileOutputStream fos = new FileOutputStream(newFile)) {
            byte[] buffer = new byte[1024];
            int bytesRead;
            while ((bytesRead = zis.read(buffer)) != -1) {
                fos.write(buffer, 0, bytesRead);
            }
        }
    }
}

3. 读取ZIP文件中的所有文件和目录：

import java.io.*;
import java.util.zip.*;
import java.util.*;

public class ReadZipFile {
    public static void main(String[] args) {
        String zipFileName = "example.zip";

        try (ZipInputStream zis = new ZipInputStream(new FileInputStream(zipFileName))) {
            ZipEntry zipEntry;
            while ((zipEntry = zis.getNextEntry()) != null) {
                System.out.println("Entry: " + zipEntry.getName());

                if (zipEntry.isDirectory()) {
                    System.out.println("Directory: " + zipEntry.getName());
                } else {
                    System.out.println("File: " + zipEntry.getName());
                }

                zis.closeEntry();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

这些示例展示了如何在Java中创建、提取和读取ZIP文件。你可以根据需要修改这些示例以满足你的具体需求。
