Velocity初体验

2、创建1个java文件，HelloVelocity.java，内容：

package com.javayou.velocity;

import java.io.StringWriter;

import java.util.*;

import org.apache.velocity.app.VelocityEngine;

import org.apache.velocity.Template;

import org.apache.velocity.VelocityContext;

/**

*/

public class HelloVelocity {

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

//初始化并取得Velocity引擎

VelocityEngine ve = new VelocityEngine();

ve.init();

//取得velocity的模版

Template t = ve.getTemplate("hellovelocity.vm");

//取得velocity的上下文context

VelocityContext context = new VelocityContext();

//把数据填入上下文

context.put("name", "Liang");

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

//为后面的展示，提前输入List数值

List temp = new ArrayList();

temp.add("1");

temp.add("2");

context.put("list", temp);

//输出流

StringWriter writer = new StringWriter();

//转换输出

t.merge(context, writer);

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

}

看完这篇，您有何感觉呢？
