解决Java原生压缩组件不支持中文文件名乱码的问题
最近发现Java原生的Zip压缩组件在压缩过程中,不支持文件名的中文编码,会在压缩过程中把中文文件名变成乱码。Apache的ant包中的压缩组件修复了这个问题,如果你在使用压缩功能时需要支持中文文件名,建议你直接使用Apache的压缩组件来实现这个功能。
具体使用方法:
1.在你的pom文件中增加对Apache的ant工具包的dependency:
<dependency> <groupId>org.apache.ant</groupId> <artifactId>ant</artifactId> <version>1.9.3</version> </dependency>
并在头部引用用到的类:
import org.apache.tools.zip.ZipEntry; import org.apache.tools.zip.ZipFile; import org.apache.tools.zip.ZipOutputStream;
2.压缩的方法实现,大家注意,本组件支持设置编码(setEncoding("GBK")方法),解决了中文编码的问题:
public static void compress(String srcPath , String dstPath) throws IOException{ File srcFile = new File(srcPath); File dstFile = new File(dstPath); if (!srcFile.exists()) { throw new FileNotFoundException(srcPath + "does not exists"); } FileOutputStream out = null; ZipOutputStream zipOut = null; try { out = new FileOutputStream(dstFile); zipOut = new ZipOutputStream(new BufferedOutputStream(out)); zipOut.setEncoding("GBK"); String baseDir = ""; compress(srcFile, zipOut, baseDir); } catch (Throwable ex){ throw new RuntimeException(ex); } finally { if(null != zipOut){ zipOut.close(); out = null; } if(null != out){ out.close(); } } } private static void compress(File file, ZipOutputStream zipOut, String baseDir) throws IOException{ if (file.isDirectory()) { compressDirectory(file, zipOut, baseDir); } else { compressFile(file, zipOut, baseDir); } } /** 压缩一个目录 */ private static void compressDirectory(File dir, ZipOutputStream zipOut, String baseDir) throws IOException{ File[] files = dir.listFiles(); for (int i = 0; i < files.length; i++) { compress(files[i], zipOut, baseDir + dir.getName() + "/"); } } /** 压缩一个文件 */ private static void compressFile(File file, ZipOutputStream zipOut, String baseDir) throws IOException{ if (!file.exists()){ return; } BufferedInputStream bis = null; try { bis = new BufferedInputStream(new FileInputStream(file)); ZipEntry entry = new ZipEntry(baseDir + file.getName()); zipOut.putNextEntry(entry); int count; byte data[] = new byte[BUFFER]; while ((count = bis.read(data, 0, BUFFER)) != -1) { zipOut.write(data, 0, count); } }finally { if(null != bis){ bis.close(); } } }
3.解压缩的实现:
public static void decompress(String zipFile , String dstPath)throws IOException{ File pathFile = new File(dstPath); if(!pathFile.exists()){ pathFile.mkdirs(); } ZipFile zip = new ZipFile(zipFile); for(Enumeration entries = zip.getEntries();entries.hasMoreElements();){ ZipEntry entry = (ZipEntry)entries.nextElement(); String zipEntryName = entry.getName(); InputStream in = null; OutputStream out = null; try{ in = zip.getInputStream(entry); String outPath = (dstPath+"/"+zipEntryName).replaceAll("\\*", "/");; //判断路径是否存在,不存在则创建文件路径 File file = new File(outPath.substring(0, outPath.lastIndexOf('/'))); if(!file.exists()){ file.mkdirs(); } //判断文件全路径是否为文件夹,如果是上面已经上传,不需要解压 if(new File(outPath).isDirectory()){ continue; } out = new FileOutputStream(outPath); byte[] buf1 = new byte[1024]; int len; while((len=in.read(buf1))>0){ out.write(buf1,0,len); } } finally { if(null != in){ in.close(); } if(null != out){ out.close(); } } } }
以上代码经过测试,可以直接使用。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
