Java read XML configuration file and properties configuration file

1. Reading XML

Parsing XML using dom4j:http://sourceforge.net/projects/dom4j/files/

1. Import org.dom4j.Document;
2. Import org.dom4j.Element;
3. Import Org.dom4j.io.SAXReader;

Try{File F=NewFile (filename); if(!f.exists ()) {System.out.println ("Error:config file doesn ' t exist!"); System.exit (1); } Saxreader Reader=NewSaxreader ();              Document Doc; Doc=Reader.read (f); Element Root=doc.getrootelement ();              Element data; Iterator<?> ITR = Root.elementiterator ("VALUE")); Data=(Element) itr.next (); Config.server= Data.elementtext ("Server"). Trim (); Config.user= Data.elementtext ("User"). Trim (); Config.pass= Data.elementtext ("Pass"). Trim (); Config.port= Data.elementtext ("Port"). Trim (); Config.dbname= Data.elementtext ("dbname"). Trim (); } Catch(Exception ex) {System.out.println ("Error:" +ex.tostring ()); }  

Test XML

<?XML version= "1.0" encoding= "UTF-8"?>  <CONFIG>      <VALUE>          <!--MySQL connection settings -          <Server>127.0.0.1</Server>          <dbname>Users</dbname>          <User>Root</User>          <Pass>Pass</Pass>          <Port>3306</Port>      </VALUE>  </CONFIG> 

2. Read properties

New Properties (); //         ClassLoader ClassLoader = This.getclass (). getClassLoader (); //         InputStream is = Classloader.getresourceasstream ("/healthfile.properties");         This . Getservletcontext ();         = Context.getresourceasstream ("/web-inf/classes/healthfile.properties");        Prop.load (is);        Is.close ();         = Prop.getproperty ("Impl.class");         = Prop.getproperty ("Statichtml.local.rootPath");
