需要做的准备工作有:
1、建立一个Java工程,需要引用Velocity相关的jar包,这些jar包可从apache.org下载到最新版本。 下载地址在:http://velocity.apache.org/download.cgi 。我下载的文件是velocity-tools-2.0.zip,将这些文件导入到项目中,就可以使用Velocity进行编码了。
2、安装Eclipse上的Velocity插件Veloedit。因为googlecode被gfw墙掉了,没有条件的朋友们可以安装网上下载到的离线安装版。这里还有一个需要注意,我的Eclipse版本为 Luna Service Release 1 (4.4.1),这个版本必须要先利用Eclipse自带的update功能,下载“Elipse Tests, Examples, and Extras”。
建立一个JavaProject,取名VelocityTool,里面新建两个java文件。
其中,VelocityHelper.java包含一个Velocity模板转换工具类,代码如下:
import java.io.File;import java.io.FileWriter;import org.apache.velocity.Template;import org.apache.velocity.VelocityContext;import org.apache.velocity.app.Velocity;import org.apache.velocity.app.VelocityEngine;/** * * @文件名称 VelocityHelper.java * @文件作者 Tsybius2014 * @创建时间 2016年5月10日 下午2:14:01 */public class VelocityHelper { /** * * @param inputVmFilePath * @param outputHtmlFilePath * @param context * @throws Exception */ public static void generateHtml(String inputVmFilePath, String outputHtmlFilePath, VelocityContext context) throws Exception { try { Velocity.init(); VelocityEngine engine = new VelocityEngine(); Template template = engine.getTemplate(inputVmFilePath, "gbk"); File outputFile = new File(outputHtmlFilePath); FileWriter writer = new FileWriter(outputFile); template.merge(context, writer); writer.close(); } catch (Exception ex) { throw ex; } }}
VelocityTool.java中有main函数,代码如下:
import java.util.HashMap;import java.util.Vector;import org.apache.velocity.VelocityContext;/** * * @文件名称 VelocityTool.java * @文件作者 Tsybius2014 * @创建时间 2016年5月10日 上午10:03:59 */public class VelocityTool { public static void main(String[] args) { try { VelocityContext context= new VelocityContext(); context.put("name", "Kim Jung-un"); context.put("gender", "Male"); context.put("email", "XXX@XXX.gov"); context.put("job", "Chairman of the WPK"); context.put("company", "Workers' Party Of Korea (WPK)"); context.put("address", "XXXXXXXXX, Pyongyang, North Korea"); context.put("portraitPath", "https://www.gxlcms.com/file:///C:/Users/Tsybius/Desktop/kju.jpg"); HashMaphashMapContact = new HashMap (); hashMapContact.put("Tel", "XXX-XXXXXXXX"); hashMapContact.put("Fax", "XXX-XXXXXXXX"); hashMapContact.put("Mobile", "XXX-XXXX-XXXX"); context.put("contactItems", hashMapContact); Vector vectorRemark = new Vector (); vectorRemark.add("Kim Jong-un is the Chairman of the Workers' Party of Korea and supreme leader of the Democratic People's Republic of Korea (DPRK), commonly referred to as North Korea."); vectorRemark.add("Kim is the son of Kim Jong-il (1941–2011) and the grandson of Kim Il-sung (1912–1994)."); vectorRemark.add("Kim obtained two degrees, one in Physics at Kim Il-sung University, and another as an Army officer at the Kim Il-sung Military University."); vectorRemark.add("Kim was named the World's 46th Most Powerful Person by the Forbes list of The World's Most Powerful People in 2013"); context.put("remarks", vectorRemark); VelocityHelper.generateHtml( "velocity_test.vm", "C:\\Users\\Tsybius\\Desktop\\output.html", context); System.out.println("生成完毕"); } catch (Exception ex) { ex.printStackTrace(); } }}
模板velocity_test.vm是一个存储着人物通讯录的模板,代码如下:
#set($docDesc="VelocityTest")#set($docAuthor="Tsybius2014")#set($docDateTime="2016-05-10 14:29:04")#set($docRemark="none")$!{name}
Address Book - $!{name} | |||||||||||||||||
| |||||||||||||||||
| |||||||||||||||||
|
以JavaApplication的方式运行本工程后,生成的HTML页面output.html如下:
Kim Jung-un
Address Book - Kim Jung-un | ||||||||||||||||||
| ||||||||||||||||||
| ||||||||||||||||||
|
使用 Firefox 46.0.1 打开此页面后效果图如下:
