java.util.zip.ZipException：无效的条目压缩大小（预期449但得到455字节）

Question

将文件从一个zipfile子文件夹复制到其他zipfile子文件夹。 version和folder是从前端获取的子文件夹名称。

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("/");

    }
    return "RestoredSuccessfully";
}

获得如下错误：

我在zipout.closeEntry();收到错误 但我无法删除此行。

Answer 1

使用新zipentry的新流解决了错误。

loc_ze = new ZipEntry(zEntry.getName()); 
zipout.putNextEntry(loc_ze); 
zipfile = new ZipFile(sourceFile); 
InputStream stream = zipfile.getInputStream(zEntry); 
while ((len = stream.read(b)) != -1) { 
    zipout.write(b, 0, len); 
}

Answer 2

您需要创建一个新的RewriteEngine On RewriteCond %{HTTP_HOST} ^www.name.com [NC] RewriteRule ^(.*)$ http://name.com/$1 [L,R=301] AddDefaultCharset UTF-8 RewriteRule ^/(css|js|img)/(.*)?$ /$1/$2 [L,QSA,R=301] RewriteRule ^([a-zA-Z0-9-/]+)/([a-zA-Z0-9-/]+)/?$ detail.php?title=$1&id=$2 RewriteRule ^([a-zA-Z0-9-/]+)/?$ detail.php?id=$1 Options -Indexes 对象以放入ZIP输出流。您不能重复使用ZIP输入流中的一个：它包含ZIP输出流想要为自己确定的内容。使用适当的构造函数从源ZEntry复制真正需要的内容。

Answer 3

也许最简单的解决方案是 TrueZip （https://truezip.java.net/），请参阅此帖子Appending files to a zip file with Java

EJP是对的。要复制同一存档中的文件，您需要两个ZipEntry对象，因为每个ZipEntry对象代表zip存档中的一个文件或目录

请参阅此主题Reading text files in a zip archive和此链接http://www.java2s.com/Code/Java/File-Input-Output/ReadingtheContentsofaZIPFile.htm

您需要一个ZipFile对象，您可以将zip文件的位置路径传递给

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

然后创建ZipFile对象的所有元素的枚举

Enumeration entries = zf.entries();

如果要复制存档中的文件，可以跳过此步骤。 [>要读取条目的内容，请使用包装到BufferedReader中的InputStream（二进制到ASCII）（读取文本文件，格式字符如EOL或EOF）BufferedReader br = new BufferedReader(new InputStreamReader(input, "UTF-8")); ] < /强>

另一种方法是ZipInputStream / ZipOutputStream

以下代码读取zip存档（http://www.java2s.com/Code/Java/File-Input-Output/ReadingtheContentsofaZIPFile.htm）的内容：

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 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();
}
