采用字符串作為模板內容的 Velocity簡單實例。

package com.test.velocity;

import java.io.StringWriter;
import java.util.Date;

import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;

public class HelloVelocity {

/**
* @param args
*/
public static void main(String[] args) throws Exception {

  // 初始化並取得Velocity引擎
  VelocityEngine ve = new VelocityEngine();
  ve.init();

// 取得velocity的模版內容, 模板內容來自字符傳

  String content = "";
  content += "Welcome $name to Javayou.com! ";
  content += " today is $date.";

// 取得velocity的上下文context
VelocityContext context = new VelocityContext();

// 把數據填入上下文
context.put("name", "javaboy2012");

context.put("date", (new Date()).toString());

// 輸出流
StringWriter writer = new StringWriter();

// 轉換輸出

ve.evaluate(context, writer, "", content); // 關鍵方法

System.out.println(writer.toString());

}
