1、遇到的问题：在for循环操作zip文件(文件名包含中文)的过程中，报错如下：
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)
2、查找原因：追查报错代码行至 ZipCoder.java:58
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);
}
可以发现，如果不指定编码的时候，默认是UTF-8，在解码的时候就会发生错误。
3、解决方法：在创建zip的时候，指定编码
FileInputStream fileInputStream = new FileInputStream(zipPath);
Charset gbk = Charset.forName("gbk");
ZipInputStream zin = new ZipInputStream(fileInputStream,gbk);
ZipEntry entry = zin.getNextEntry();
