java.util.zip.ZipException：無効なエントリの圧縮サイズ（予想される449,445バイト）

Question

あるzipfileサブフォルダから他のzipfileサブフォルダにファイルをコピーします。 versionおよびfolderは、フロントエンドから取得するサブフォルダ名です。

public String restore(String jobId, String version, String folder) { 
    String fileName = String.valueOf(jobId) + ".zip"; 
    String versions[] = version.replaceAll("'", "") 
     .replace("[", "") 
     .replace("]", "") 
     .split(","); 
    String folders[] = folder.replaceAll("'", "").replace("[", "").replace("]", "").split(","); 
    ArrayList<String> listofVersion, listofFolder = new ArrayList<>(); 

    File destinationFile = new File(env.getProperty("file.path") + fileName); 
    File sourceFile = new File(env.getProperty("file.arcivePath") + fileName); 

    FileInputStream in; 
    FileOutputStream out; 
    ZipInputStream zin; 
    ZipOutputStream zipout; 
    int BUFFER = (int) sourceFile.length(); 

    if (!destinationFile.exists()) { 
     try { 
      out = new FileOutputStream(destinationFile); 
      zipout = new ZipOutputStream(out); //I get the "out" object from the servlet which tells the content type and and final zip file location. 
      ZipEntry zEntry, ze; 
      in = new FileInputStream(sourceFile); 
      zin = new ZipInputStream(in); 
      while ((zEntry = zin.getNextEntry()) != null) { 
       System.out.println(zEntry); 
       String entry = zEntry.getName(); 
       String entryList[] = entry.split("/"); 
       if (zEntry.isDirectory() && (entryList.length <= 1)) { 
        zipout.putNextEntry(zEntry); 
       } else { 
        if (entryList.length >= 2) { 
         listofVersion = listVersionRestore(fileName); 
         for (int j = 0; j < versions.length; j++) { 
          for (int i = 0; i < listofVersion.size(); i++) { 
           if (listofVersion.get(i).equals(versions[j])) { 
            if ((entryList.length == 2) && entryList[1].equals(versions[j])) { 
             zipout.putNextEntry(zEntry); 
            } 
            if (entryList.length >= 3) { 
             listofFolder = listFolderRestore(fileName, versions[j]); 
             for (int l = 0; l < folders.length; l++) { 
              for (int k = 0; k < listofFolder.size(); k++) { 
               if (listofFolder.get(k).equals(folders[l])) { 
                if ((entryList.length == 3) && entryList[1].equals(versions[j]) && entryList[2].equals(folders[l])) { 
                 zipout.putNextEntry(zEntry); 
                } 

                if ((entryList.length == 4) && entryList[1].equals(versions[j]) && entryList[2].equals(folders[l])) { 
                 zipout.putNextEntry(zEntry); 
                 byte[] buffer = new byte[BUFFER]; 
                 int len = 0; 
                 while ((len = zin.read(buffer)) != -1) { 
                  zipout.write(buffer, 0, len); 
                 } 

                 zipout.closeEntry(); 
                 in.close(); 
                } 

               } 
              } 
             } 
            } 
           } 
          } 
         } 
        } 
       } 
      } 
      zipout.close(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
      return "Error"; 
     } 
    } else { 
     return "Already Exists"; 
    } 
    return "RestoredSuccessfully"; 
} 

次のようにエラー行き方：私はzipout.closeEntry(); でエラーを取得しています。しかし、私はこの行を削除することはできません

を。

Answer 1

新しいZEntryオブジェクトを作成して、ZIP出力ストリームに挿入する必要があります。あなたはZIP入力ストリームからそれを再利用することはできません。それは、ZIP出力ストリームがそれ自身のために決定したいものを含んでいます。適切なコンストラクタを使用して、ソースZIPEntryから実際に必要なものをコピーします。

Answer 2

たぶん最も簡単な解決策は、TrueZip（https://truezip.java.net/）で、EJPが正しいこのスレッドにAppending files to a zip file with Java

を参照してください。すべてのZipEntryオブジェクトはzipアーカイブ

内の1つのファイルまたはディレクトリを表すので、同じアーカイブ内のファイルをコピーするための次の2つのZipEntryオブジェクトを必要とするhttp://www.java2s.com/Code/Java/File-Input-Output/ReadingtheContentsofaZIPFile.htm

は、あなたが通過するにZipFileオブジェクトが必要です。このスレッドReading text files in a zip archiveと、このリンクを参照してください。 zipファイルのロケーションパス

ZipFile zf = new ZipFile("/<path>/yourZip.zip");

その後

あなたはZIPファイルオブジェクトのすべての要素の列挙を作成

Enumeration entries = zf.entries();

アーカイブ内のファイルをコピーしたいので、これをスキップできます。 別の方法は、/ ZipInputStreamで

[エントリの内容を読み取るためには、入力ストリーム（ASCIIバイナリ）BufferedReaderのにラップ（EOLまたはEOFのような形式の文字で、テキストファイルを読み取る）BufferedReader br = new BufferedReader(new InputStreamReader(input, "UTF-8"));を使用します] ZipOutputStream

次のコードは、zipアーカイブ（http://www.java2s.com/Code/Java/File-Input-Output/ReadingtheContentsofaZIPFile.htm）の内容を読み取ります

import java.io.BufferedReader; 
import java.io.IOException; 
import java.io.InputStreamReader; 
import java.util.Enumeration; 
import java.util.zip.ZipEntry; 
import java.util.zip.ZipFile; 

public class ReadZip { 
    public static void main(String args[]) { 
    try { 
     ZipFile zf = new ZipFile("ReadZip.zip"); 
     Enumeration entries = zf.entries(); 

     BufferedReader input = new BufferedReader(new InputStreamReader(
      System.in)); 
     while (entries.hasMoreElements()) { 
     ZipEntry ze = (ZipEntry) entries.nextElement(); 
     System.out.println("Read " + ze.getName() + "?"); 
     String inputLine = input.readLine(); 
     if (inputLine.equalsIgnoreCase("yes")) { 
      long size = ze.getSize(); 
      if (size > 0) { 
      System.out.println("Length is " + size); 
      BufferedReader br = new BufferedReader(
       new InputStreamReader(zf.getInputStream(ze))); 
      String line; 
      while ((line = br.readLine()) != null) { 
       System.out.println(line); 
      } 
      br.close(); 
      } 
     } 
     } 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    } 
} 

Answer 3

解決エラーたちによって新たなジェントリーで新しいストリームを作り出す。

Answer 4

static copyZip() throws IOException { 
    try (final ZipInputStream zis = new ZipInputStream(...); 
     final ZipOutputStream zos = new ZipOutputStream(...) 
    ) { 
     copyZipContent(zis, zos); 
    } 
} 

static void copyZipContent(final ZipInputStream zis, final ZipOutputStream zos) throws IOException { 
    ZipEntry zisEntry; 
    while ((zisEntry = zis.getNextEntry()) != null) { 
     ZipEntry zosEntry = new ZipEntry(zisEntry.getName()); 
     zosEntry.setComment(zisEntry.getComment()); 
     zosEntry.setExtra(zisEntry.getExtra()); 
     zos.putNextEntry(zosEntry); 
     IOUtils.copy(zis, zos); 
     zos.closeEntry(); 
    } 
    zos.finish(); 
}
