我有一个servlet,它接受包含XML文件的ZIP文件。我想阅读那些xml文件的内容,但我得到一个java.io.IOException:Stream关闭。
我得到这样的ZIP:
private byte[] getZipFromRequest(HttpServletRequest request) throws IOException {
byte[] body = new byte[request.getContentLength()];
new DataInputStream(request.getInputStream()).readFully(body);
return body;
}
我这样读了:
public static void readZip(byte[] zip) throws IOException {
ByteArrayInputStream in = new ByteArrayInputStream(zip);
ZipInputStream zis = new ZipInputStream(in);
ZipEntry entry;
while ((entry = zis.getNextEntry()) != null) {
System.out.println(String.format("Entry: %s len %d", entry.getName(), entry.getSize()));
BufferedReader br = new BufferedReader(new InputStreamReader(zis, "UTF-8"));
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
br.close();
}
zis.close();
}
输出:
Entry: file.xml len 3459
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<test>
correct content of my xml file
</test>
java.io.IOException: Stream closed
at java.util.zip.ZipInputStream.ensureOpen(ZipInputStream.java:67)
at java.util.zip.ZipInputStream.getNextEntry(ZipInputStream.java:116)
at util.ZipHelper.readZip(ZipHelper.java:26)
我的问题
为什么我在这条线上得到这个例子?
while ((entry = zis.getNextEntry()) != null) {
我错过了什么?
答案 0 :(得分:5)
您正在使用zis
包裹BufferedReader
,因此当您关闭br
时,zis
也会关闭。
因此删除br.close
迭代将继续进行,没有任何异常。
