Java中使用通配符指定文件路径解压Zip文件报错求助

需要解压指定文件夹中文件名不固定的文件，尝试在路径中使用通配符detailedreport_*.zip，但出现如下错误：

java.io.FileNotFoundException: C:\SAST\Downloaded XML Files\detailedreport_*.zip (文件名、目录名或卷标语法不正确)

原代码如下：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.stream.Collectors;
import java.util.stream.Stream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class UnzipFiles {
    
    
    public static void main(String[] args) {
        
        String zipFilePath = "C:\\SAST\\Downloaded XML Files\\detailedreport_*.zip";
        String zipFilePath2 = "C:\\SAST\\Downloaded XML Files\\detailedreport_*.zip";
        
        
        String destDir = "C:\\SAST\\Downloaded XML Files\\Unzipped Files";
        String destDir2 = "C:\\SAST\\Downloaded XML Files\\Unzipped Files";
        
        unzip(zipFilePath,destDir);
        unzip2(zipFilePath2,destDir2); 
       
    }

    private static void unzip(String zipFilePath,String destDir) {
        File dir = new File(destDir);
        // create output directory if it doesn't exist
        if(!dir.exists()) dir.mkdirs();
        FileInputStream fis;
        //buffer for read and write data to file
        byte[] buffer = new byte[1024];
        try {
            fis = new FileInputStream(zipFilePath);
            ZipInputStream zis = new ZipInputStream(fis);
            ZipEntry ze = zis.getNextEntry();
          
            while(ze != null){
                String fileName = ze.getName();
                File newFile = new File(destDir + File.separator + fileName);
                System.out.println("Unzipping to "+newFile.getAbsolutePath());
                //create directories for sub directories in zip
                new File(newFile.getParent()).mkdirs();
                FileOutputStream fos = new FileOutputStream(newFile);
                int len;
                while ((len = zis.read(buffer)) > 0) {
                fos.write(buffer, 0, len);
                }
                fos.close();
                //close this ZipEntry
                zis.closeEntry();
                ze = zis.getNextEntry();
            }
            //close last ZipEntry
            zis.closeEntry();
            zis.close();
            fis.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        
    }
    
    private static void unzip2(String zipFilePath2,String destDir2) {
        File dir2 = new File(destDir2);
        // create output directory if it doesn't exist
        if(!dir2.exists()) dir2.mkdirs();
        FileInputStream fis2;
        //buffer for read and write data to file
        byte[] buffer2 = new byte[1024];
        try {
            fis2 = new FileInputStream(zipFilePath2);
            ZipInputStream zis2 = new ZipInputStream(fis2);
            ZipEntry ze2 = zis2.getNextEntry();
          
            while(ze2 != null){
                String fileName2 = ze2.getName();
                File newFile2 = new File(destDir2 + File.separator + fileName2);
                System.out.println("Unzipping to "+newFile2.getAbsolutePath());
                //create directories for sub directories in zip
                new File(newFile2.getParent()).mkdirs();
                FileOutputStream fos2 = new FileOutputStream(newFile2);
                int len2;
                while ((len2 = zis2.read(buffer2)) > 0) {
                fos2.write(buffer2, 0, len2);
                }
                fos2.close();
                //close this ZipEntry
                zis2.closeEntry();
                ze2 = zis2.getNextEntry();
            }
            //close last ZipEntry
            zis2.closeEntry();
            zis2.close();
            fis2.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        
    }

}

Java的FileInputStream等传统IO类不支持直接解析路径中的通配符，必须先手动匹配符合规则的文件，再逐个处理。以下是优化后的实现：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.stream.Stream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class UnzipFiles {

    public static void main(String[] args) {
        String targetDir = "C:\\SAST\\Downloaded XML Files";
        String destDir = "C:\\SAST\\Downloaded XML Files\\Unzipped Files";
        
        // 筛选符合detailedreport_*.zip格式的文件
        try (Stream<Path> paths = Files.list(Paths.get(targetDir))) {
            paths.filter(path -> path.getFileName().toString().matches("detailedreport_.*\\.zip"))
                 .forEach(path -> unzip(path.toString(), destDir));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    // 统一的解压方法
    private static void unzip(String zipFilePath, String destDir) {
        File dir = new File(destDir);
        if (!dir.exists()) dir.mkdirs();
        
        byte[] buffer = new byte[1024];
        // 使用try-with-resources自动关闭流，避免资源泄漏
        try (FileInputStream fis = new FileInputStream(zipFilePath);
             ZipInputStream zis = new ZipInputStream(fis)) {
            
            ZipEntry ze;
            while ((ze = zis.getNextEntry()) != null) {
                String fileName = ze.getName();
                File newFile = new File(destDir + File.separator + fileName);
                System.out.println("Unzipping to " + newFile.getAbsolutePath());
                
                // 创建文件的父目录
                new File(newFile.getParent()).mkdirs();
                
                try (FileOutputStream fos = new FileOutputStream(newFile)) {
                    int len;
                    while ((len = zis.read(buffer)) > 0) {
                        fos.write(buffer, 0, len);
                    }
                }
                zis.closeEntry();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

• 通配符匹配：用正则表达式detailedreport_.*\\.zip匹配文件名，.*代表任意字符序列，\\.是转义的点号（正则中.默认匹配任意字符）。
• 资源管理：使用try-with-resources语法自动关闭流，无需手动调用close方法，避免资源泄漏。
• 代码复用：删除重复的unzip2方法，统一用unzip处理所有符合条件的文件。
