java.util.zip.ZipError：CEN标头无效（签名错误） [英] java.util.zip.ZipError: invalid CEN header (bad signature)

问题描述

我在Red Hat Linux上使用Java 1.7.0_40，我有以下代码：

I'm using Java 1.7.0_40 on Red Hat Linux and I have the following code:

Path zipfile = Paths.get(filename);
FileSystem fs = FileSystems.newFileSystem(zipfile, FileTest.class.getClassLoader());

文件名变量指向一个zip文件那是788MB。 zip文件的未压缩大小为8.3GB。当我运行上面的代码时，我得到以下异常：

The filename variable points to a zip file that is 788MB. The uncompressed size of the zip file is 8.3GB. When I run the code above I get the following exception:

Exception in thread "main" java.util.zip.ZipError: invalid CEN header (bad signature)
        at com.sun.nio.zipfs.ZipFileSystem.zerror(ZipFileSystem.java:1605)
        at com.sun.nio.zipfs.ZipFileSystem.initCEN(ZipFileSystem.java:1058)

        at FileTest.readFromZip(FileTest.java:35)
        at FileTest.main(FileTest.java:25)

我的印象是Java 7能够处理大型zip文件。任何人都可以解释为什么会发生这种情况吗？

I was under the impression that Java 7 was capable of handling large zip files. Can anyone explain why this is happening?

谢谢。

推荐答案

我也在基于Maven的项目中遇到了这个问题。出现问题的原因是罐子腐烂了。从.m2文件夹中删除了jar并重新构建了项目;它就像魅力一样。

I too faced the issue in Maven based project. The issue occurred because of corrupted jars. Deleted the jars from .m2 folder and built the project again; and it worked like charm.
