java实现解压zip文件并读取内容

你可以使用Java的java.util.zip包来实现解压zip文件并读取其内容。下面是一个示例代码：

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class UnzipExample {
    public static void main(String[] args) {
        String zipFilePath = "path/to/your/zip/file.zip";
        String destinationFolder = "path/to/destination/folder";
        
        try {
            unzip(zipFilePath, destinationFolder);
            readContents(destinationFolder);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    public static void unzip(String zipFilePath, String destinationFolder) throws IOException {
        byte[] buffer = new byte[1024];
        File folder = new File(destinationFolder);
        if (!folder.exists()) {
            folder.mkdirs();
        }
        
        try (ZipInputStream zipInputStream = new ZipInputStream(new BufferedInputStream(new FileInputStream(zipFilePath)))) {
            ZipEntry zipEntry;
            while ((zipEntry = zipInputStream.getNextEntry()) != null) {
                String entryName = zipEntry.getName();
                File entryFile = new File(destinationFolder + File.separator + entryName);
                
                if (entryFile.getParentFile() != null && !entryFile.getParentFile().exists()) {
                    entryFile.getParentFile().mkdirs();
                }
                
                if (!zipEntry.isDirectory()) {
                    int bytesRead;
                    while ((bytesRead = zipInputStream.read(buffer)) != -1) {
                        entryFile.createNewFile();
                        FileOutputStream fileOutputStream = new FileOutputStream(entryFile);
                        fileOutputStream.write(buffer, 0, bytesRead);
                        fileOutputStream.close();
                    }
                } else {
                    entryFile.mkdirs();
                }
                
                zipInputStream.closeEntry();
            }
        }
    }
    
    public static void readContents(String folderPath) {
        File folder = new File(folderPath);
        if (folder.exists() && folder.isDirectory()) {
            File[] files = folder.listFiles();
            
            if (files != null) {
                for (File file : files) {
                    if (file.isDirectory()) {
                        System.out.println("Directory: " + file.getName());
                    } else {
                        System.out.println("File: " + file.getName());
                    }
                }
            }
        }
    }
}

在上述示例代码中，你需要替换`zipFilePath`和`destinationFolder`变量的值为你实际的zip文件路径和解压后的目标文件夹路径。`unzip`方法负责解压zip文件，`readContents`方法用于读取解压后的文件夹内容并打印。

请确保你已经正确配置了Java环境，并导入了必要的类和包。运行示例代码后，它将解压zip文件并打印出解压后的文件和文件夹列表。
