Velocity之Hello World(入门实例)

参考:http://blog.csdn.net/mengxuwq/article/details/1871161 (非常感谢这篇文章,让我初步入门)


自己调试完全能运行后,写在此,供新人参考,供自己温故


1、准备模板文件

//如下为hellosite.vm

Hello $name! Welcome to $site world!

2、准备Java文件  (补充说明:hellosite.vm、HelloWorld.java放在同一目录下)

//如下为HelloWorld.java

import java.io.StringWriter;
import org.apache.velocity.app.VelocityEngine;
import org.apache.velocity.Template;
import org.apache.velocity.VelocityContext;

public class HelloWorld{
	public static void main( String[] args )throws Exception{
	   /* first, get and initialize an engine */
	   VelocityEngine ve = new VelocityEngine();
	   ve.init();
	   
	   /* next, get the Template */
	   Template t = ve.getTemplate( "hellosite.vm" );
	   
	   /* create a context and add data */
	   VelocityContext context = new VelocityContext();
	   context.put("name", "Eiffel Qiu");
	   context.put("site", "http://www.j2medev.com");
	   
	   /* now render the template into a StringWriter */
	   StringWriter writer = new StringWriter();
	   t.merge( context, writer );
	   
	   /* show the World */
	   System.out.println( writer.toString() ); 
	}
}

3、配置Velocity所需要的jar包(本文的调试基于 velocity-1.6.3)

3.1 下载jar包

   http://velocity.apache.org/download.cgi ——>Older releases ——>最终到达 http://archive.apache.org/dist/velocity/engine/1.6.3/,找到 velocity-1.6.3.zip 下载


3.1 解压velocity-1.6.3.zip ,发现解压后的目录下存在velocity-1.6.3.jar、velocity-1.6.3-dep.jar

3.2 配置classpath环境变量,引入velocity-1.6.3.jar、velocity-1.6.3-dep.jar


4、编译运行上述Java文件,结果如下:

D:\聚划算\技术部\编程练习\Velocity\testVelocity>java HelloWor
Hello Eiffel Qiu! Welcome to http://www.j2medev.com world!


后记:

       1、调试过程中,刚开始在classpath中只设置了velocity-1.6.3.jar,调试后发现缺class,缺的class正好在velocity-1.6.3-dep.jar中,引入后问题解决
