解决方案如下：可行，
SAXReader reader = new SAXReader();
Enumeration<URL> e = Activator.context.getBundle().findEntries("/conf/", "driver.xml", true);
if(e != null) {
while(e.hasMoreElements()) {
URL url = e.nextElement();
if(url != null) {
InputStream in;
try {
in = url.openStream();
doc = reader.read(in);
break;
} catch (IOException | DocumentException e1) {
e1.printStackTrace();
}
}
}
}
