问题：
JAVAutil。拉链ZipException:没有当前的ZIP条目
乐刚毅
我正在尝试创建一个csv文件并压缩它。看起来这个异常的原因是大小（即csv中列名的字节大小计数）超过了8192字节。我想知道如何增加这个限制，是否可以或任何其他解决方案。请建议。
提前谢谢。

你不能仅仅通过复制CSV文件的内容来创建zip，你需要先创建一个zip条目。所以代码应该是这样的：
String[] csvHeaderElements = { // some headers separated with semicolon
};
try (ZipOutputStream zos = new ZipOutputStream(new FileOutputStream("C:/Users/TestUser/Downloads/test.zip"))) {
// create zip entry
ZipEntry entry = new ZipEntry("test.csv");
zos.putNextEntry(entry);
CSVPrinter csvPrinter = new CSVPrinter(new OutputStreamWriter(zos), CSVFormat.EXCEL.builder().setHeader(csvHeaderElements).build());
// some action with csvPrinter
// ...
// close entry
zos.closeEntry();
}

ZIP流需要一个条目，它将在ZIP内容中设置文件名。使用try with resources确保ZIP输出流正确关闭。本例定义了名为“somename.xyz”的条目中的内容：
try(ZipOutputStream zos = new ZipOutputStream(out)) {
zos.putNextEntry(new ZipEntry("somename.xyz"));
OutputStreamWriter wr = new OutputStreamWriter(zos);
CSVPrinter csvPrinter = new CSVPrinter(wr,
CSVFormat.EXCEL.withHeader(csvHeaderElements)
);
wr.flush();
}
或者，您可能对GZIP流感到困惑，因为GZIP流更容易设置，只需将ZipOutputStream更改为GZIPOutputStream：
try(GZIPOutputStream zos = new GZIPOutputStream(out)) {
OutputStreamWriter wr = new OutputStreamWriter(zos);
CSVPrinter csvPrinter = new CSVPrinter(wr,
CSVFormat.EXCEL.withHeader(csvHeaderElements)
);
wr.flush();
}
