java解压zip读取解压文件

以下是一个使用Java解压ZIP文件并读取解压文件的示例代码：

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;

public class UnzipExample {
    public static void main(String[] args) {
        String zipFilePath = "path/to/your/zip/file.zip";
        String destDirectory = "path/to/destination/directory";
        
        try {
            unzip(zipFilePath, destDirectory);
            
            // 读取解压后的文件
            File directory = new File(destDirectory);
            File[] files = directory.listFiles();
            if (files != null) {
                for (File file : files) {
                    if (file.isFile()) {
                        // 处理解压后的文件
                        System.out.println("File: " + file.getName());
                    }
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void unzip(String zipFilePath, String destDirectory) throws IOException {
        File destDir = new File(destDirectory);
        if (!destDir.exists()) {
            destDir.mkdir();
        }
        
        FileInputStream fis = new FileInputStream(zipFilePath);
        ZipInputStream zipIn = new ZipInputStream(fis);
        ZipEntry entry = zipIn.getNextEntry();
        
        while (entry != null) {
            String filePath = destDirectory + File.separator + entry.getName();
            if (!entry.isDirectory()) {
                extractFile(zipIn, filePath);
            } else {
                File dir = new File(filePath);
                dir.mkdir();
            }
            
            zipIn.closeEntry();
            entry = zipIn.getNextEntry();
        }
        
        zipIn.close();
        fis.close();
    }

    private static void extractFile(ZipInputStream zipIn, String filePath) throws IOException {
        BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(filePath));
        byte[] bytesIn = new byte[4096];
        int read;
        while ((read = zipIn.read(bytesIn)) != -1) {
            bos.write(bytesIn, 0, read);
        }
        bos.close();
    }
}

请注意，上述代码中的zipFilePath和destDirectory需要根据实际情况进行替换，分别指定要解压的ZIP文件路径和解压后的目标目录路径。在解压后，您可以根据需要处理解压后的文件
