Reading of resource files in servlet

Method One: Get the data flow of the resource file

         This . Getservletcontext ();         = Context.getresourceasstream ("/person.properties");         New Properties ();        Pt.load (is);        System.out.println (Pt.getproperty ("name"));

Method Two: Get the absolute path of the resource file, then take advantage of the FileInputStream, and the difference is that here you can get the file name to manipulate

         This . Getservletcontext ();         = Context.getrealpath ("web-inf/classes/person.properties");        System.out.println (Realpath);         = Realpath.substring (realpath.lastindexof ("\ \") +1);        SYSTEM.OUT.PRINTLN (filename);                 New FileInputStream (Realpath);                 New Properties ();        Pt.load (FIS);        System.out.println (Pt.getproperty ("name"));

Get the resource profile in the normal class because there are no ServletContext objects in the normal class, so use the ClassLoader

        URL url = Persondao. class. getClassLoader (). GetResource ("com/baowei/servlet/person.properties");         = Url.getpath ();        SYSTEM.OUT.PRINTLN (filepath);                 New FileInputStream (filepath);         New Properties ();         pt.load (FIS);        System.out.println (Pt.getproperty ("name"));        System.out.println (Pt.getproperty ("age"));
