一、遇到的问题:在for循环操做zip文件(文件名包含中文)的过程当中,报错以下: java
Exception in thread "main" java.lang.IllegalArgumentException: MALFORMED at java.util.zip.ZipCoder.toString(ZipCoder.java:58) at java.util.zip.ZipInputStream.readLOC(ZipInputStream.java:297) at java.util.zip.ZipInputStream.getNextEntry(ZipInputStream.java:121) at com.forestfood.FileUntils.done(FileUntils.java:224) at com.forestfood.FileUntils.getActionZipFiles(FileUntils.java:196) at com.forestfood.FileUntils.main(FileUntils.java:24)
二、查找缘由:追查报错代码行至 ZipCoder.java:58编码
final class ZipCoder { String toString(byte[] ba, int length) { CharsetDecoder cd = decoder().reset(); int len = (int)(length * cd.maxCharsPerByte()); char[] ca = new char[len]; if (len == 0) return new String(ca); // UTF-8 only for now. Other ArrayDeocder only handles // CodingErrorAction.REPLACE mode. ZipCoder uses // REPORT mode. if (isUTF8 && cd instanceof ArrayDecoder) { int clen = ((ArrayDecoder)cd).decode(ba, 0, length, ca); if (clen == -1) // malformed throw new IllegalArgumentException("MALFORMED"); return new String(ca, 0, clen); }
能够发现,若是不指定编码的时候,默认是UTF-8,在解码的时候就会发生错误。spa
三、解决方法:在建立zip的时候,指定编码rest
FileInputStream fileInputStream = new FileInputStream(zipPath); Charset gbk = Charset.forName("gbk"); ZipInputStream zin = new ZipInputStream(fileInputStream,gbk); ZipEntry entry = zin.getNextEntry();
