一、遇到的問題:在for循環操做zip文件(文件名包含中文)的過程當中,報錯以下: 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、查找緣由:追查報錯代碼行至 ZipCoder.java:58編碼
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); }
能夠發現,若是不指定編碼的時候,默認是UTF-8,在解碼的時候就會發生錯誤。spa
三、解決方法:在建立zip的時候,指定編碼rest
FileInputStream fileInputStream = new FileInputStream(zipPath); Charset gbk = Charset.forName("gbk"); ZipInputStream zin = new ZipInputStream(fileInputStream,gbk); ZipEntry entry = zin.getNextEntry();
