关于Java解压Zip文件的java.lang.IllegalArgumentException:MALFORMED报错问题。

java报错

java.lang.IllegalArgumentException:MALFORMEDat java.util.zip.ZipCoder.toString(ZipCoder.toString:58)......

首先在网上查了下这个异常的原因，都说是因为编码的问题，要求将UTF-8改成GBK就可以了。
然后找到ZipCoder.toString方法的58行

    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)    // malformedthrow new IllegalArgumentException("MALFORMED");return new String(ca, 0, clen);}ByteBuffer bb = ByteBuffer.wrap(ba, 0, length);CharBuffer cb = CharBuffer.wrap(ca);CoderResult cr = cd.decode(bb, cb, true);if (!cr.isUnderflow())throw new IllegalArgumentException(cr.toString());cr = cd.flush(cb);if (!cr.isUnderflow())throw new IllegalArgumentException(cr.toString());return new String(ca, 0, cb.position());}

这里只有UTF-8才会进入if逻辑才会抛出异常？果然如网上所说，将编码格式改为GBK即可。
ZipCoder这个是src.zip包中的，既然这里做了校验当然会有它的道理。
但是，单纯的改为GBK来解决这个bug显然是不合理的。
于是又在网上找，将原来写的
ZipInputStream 改为 ZipArchiveInputStream ；
ZipEntry 改为 ZipArchiveEntry ；
zipin.getNextEntry() 改为 zipin.getNextZipEntry() 可解决问题。
