Disable external DTD loading when saxparser parses XML

Recently, when I used saxbuilder to parse a string into a document object, I found that if the string contains an external DTD, Sax will access the URL to load this DTD. In this way, the exception java.net. connectexception: connection is easily generated.

Saxbuilder = new saxbuilder (); saxbuilder. setignoringelementcontentwhitespace (false); document DOC = saxbuilder. Build (New java. Io. stringreader (STR ));

 

You can add the followingCodeTo disable External DTD loading:

// Disable External DTD loading to prevent connection timeout exceptions saxbuilder. setfeature ("http://apache.org/xml/features/nonvalidating/load-external-dtd", false );
