下面是代码段。
FileInputStream fin = new FileInputStream(zipFile);
ZipInputStream zin = new ZipInputStream(fin);
ZipEntry entry = null;
String routerListUCM = "";
try {
entries:
while ((entry = zin.getNextEntry()) != null) {
if (entry.getName().startsWith("routes")) {
BufferedReader in = new BufferedReader(new InputStreamReader(zin, "UTF-8"));
if (true) {
//parse the xml of the route...
DOMParser dp = new DOMParser();
dp.parse(in);
Element e = (Element) dp.getDocument().getFirstChild();
String transferid = e.getElementsByTagName("transferId").item(0).getTextContent();
System.out.println("transferId=" + transferid);
int fileid = Integer.parseInt(transferid.split("-")[1]);
System.out.println("fileid=" + transferid);
String userList = e.getElementsByTagName("userList").item(0).getTextContent();
System.out.println("userList=" + userList);
String routeList = e.getElementsByTagName("routeList").item(0).getTextContent();
System.out.println("routeList=" + routeList);
routerListUCM = routeList;
if (routeList.toLowerCase().indexOf(myname().toLowerCase()) == -1) {
//my server is not in the current route...
//so skip this route table.
continue entries;
}
}
}
}
} catch (Exception e) {
System.err.println(e.getMessage());
e.printStackTrace();
}
在某些情况下,“继续输入”之后;并尝试下一个循环,我看到“ stream close Exception”:/

似乎最外面的BufferedReader
对象关闭了嵌套的流(尤其是ZipInputStream
)。尝试将BufferedReader初始化代码移到更高的循环逻辑上。
此外,该主题可能会有所帮助:closing nested streams。
更新:
好的,现在一切都清楚了。 DOMParser
类的实现代码清楚地表明,parse
方法关闭了基础InputStream
的源代码(仅是finally块的摘录):
} finally {
this.parser.reader.close();
}
在这种情况下可以采取的措施是入侵BufferedReader
对象,该对象将传递给DOMParser
对象。这是一个示例:
public class HackedReader extends BufferedReader {
public HackedReader(InputStreamReader inputStreamReader) {
super(inputStreamReader);
}
@Override
public void close() {
// Close method doesn't do anything, that's the main sense of overriding.
}
// But you know exact method which will close your underlying stream.
public void hackedClose() throws IOException {
super.close();
}
}

我发现使用org.apache.poi.util.CloseIgnoringInputStream
对我有用。我能够将要传递的ZipInputStream
包装到另一个方法中。
例如:
ExcelUtility.getLineCount(new CloseIgnoringInputStream(zipStream)
