首先需要必备的jar包：
web.xml
<!-- load velocity property -->
<servlet>
<servlet-name>velocity</servlet-name>
<servlet-class>org.apache.velocity.tools.view.servlet.VelocityLayoutServlet</servlet-class>
<init-param>
<param-name>org.apache.velocity.properties</param-name>
<param-value>/WEB-INF/velocity.properties</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>velocity</servlet-name>
<url-pattern>*.vm</url-pattern>
</servlet-mapping>
velocity.properties
input.encoding=utf-8
output.encoding=utf-8WebRoot.resource.loader.class = org.apache.velocity.tools.view.servlet.WebappLoader
webapp.resource.loader.path=/WEB-INF/vm/
后台调用：
String realpath = request.getRealPath("/"); //模板路径
String urlVm = "/WEB-INF/vm/test.vm"; //生成的html的路径，在webroot的html文件夹下面
String urlHtml = realpath+"/html/test.htm"; //设置模板中的元素
VelocityContext context = new VelocityContext();
context.put("title", "hello word "); CreateHtml.createHtml(realpath,urlVm,urlHtml,context);
CreateHtml.java
package com.velocity;import java.io.PrintWriter;
import java.util.Properties;import org.apache.velocity.Template;
import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.Velocity;public class CreateHtml {
public static void createHtml(String realpath, String urlVm,
String urlHtml, VelocityContext context) { //加载路径
Properties prop = new Properties();
prop.setProperty(Velocity.FILE_RESOURCE_LOADER_PATH, realpath);
try {
Velocity.init(prop);
//初始化vm模板
Template template = new Template();
template = Velocity.getTemplate(urlVm, "utf-8"); //生成html页面
PrintWriter writer = new PrintWriter(urlHtml);
template.merge(context, writer); //切记关闭流
writer.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} }}
这样就在服务器下生成了静态页面，页面就直接访问你生成的页面，例如：http://localhost:8080/html/test.htm
