编辑: children 是一个目录数组。此代码循环通过此数组,以便进入每个目录并将列出的所有文件加载到数组中。然后,对于每个文件,readFile 函数应该读取该文件。
我的代码是:
for (File cat: children) {
File[] webs = cat.listFiles();
System.out.println(" Indexing category: " + cat.getName());
for (File f: webs) {
Web w = readFile(f);
// Do things with w
}
}
我收到此错误:
org.htmlparser.util.ParserException: Error in opening a connection to 209800.webtrec

这很奇怪,因为我在该目录中看不到任何这些文件。
谢谢!
EDIT2:这是 readFile 函数。它将文件的内容加载到一个字符串中并解析它。实际上,文件是 html 文件。
private static Web readFile(File file) {
try {
FileInputStream fin = new FileInputStream(file);
FileChannel fch = fin.getChannel();
// map the contents of the file into ByteBuffer
ByteBuffer byteBuff = fch.map(FileChannel.MapMode.READ_ONLY,
0, fch.size());
// convert ByteBuffer to CharBuffer
// CharBuffer chBuff = Charset.defaultCharset().decode(byteBuff);
CharBuffer chBuff = Charset.forName("UTF-8").decode(byteBuff);
String f = chBuff.toString();
// Close imputstream. By doing this you close the channel associated to it
fin.close();
Parser parser = new Parser(f);
Visitor visit = new Visitor();
parser.visitAllNodesWith((NodeVisitor)visit);
return new Web(visit.getCat(), visit.getBody(), visit.getTitle());
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
