Reference Class Properties

This Example shows you how to use class properties in your velocity template.

Steps used in the code given below :
1: Initialize velocity run time engine through method init().
2: Create object of VelocityContext Class.
3: Use put() method of Class VelocityContext through object 'ctx'.
4: Define variable 'date' to hold the value of java.util.Date Class.
5: With the use of this date variable, we will access the values of day, month and year in .vm file.

CallClassMethods.java

package velocity.ClassReference;



import java.io.*;

import java.util.*;



import org.apache.velocity.*;

import org.apache.velocity.app.*;



public class CallClassMethods {



  public static void main(String args[]) throws Exception {

  Velocity.init();

  Template t = 

Velocity.getTemplate("./src/velocity/ClassReference/ClassProperties.vm");



  VelocityContext ctx = new VelocityContext();



  ctx.put("date", new Date());

  Writer writer = new StringWriter();

  t.merge(ctx, writer);



  System.out.println(writer);

  }

}

ClassMethods.vm

Day: $date.Date

Month: $date.Month

#set($year=$date.Year+1900)

Year: $year

Output :

Day: 23

Month: 7

Year: 2008
