velocity开发eclipse插件  http://code.google.com/p/veloeclipse/

目录结构
点我下载工程代码

俩实体类不用说了
看CustomerVelocityServlet类
package com.velocity.servlet;

import java.util.ArrayList;
import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.velocity.Template;
import org.apache.velocity.context.Context;
import org.apache.velocity.tools.view.servlet.VelocityViewServlet;

import com.velocity.bean.Department;
import com.velocity.bean.Employee;

@SuppressWarnings(
"serial")
public class CustomerVelocityServlet extends VelocityViewServlet{

    
    
//设置返回视图为text/html编码为gbk
    @Override
    
protected void setContentType(HttpServletRequest request,
            HttpServletResponse response) {
        response.setContentType(
"text/html;charset=gbk");
    }
    
    
//处理请求
    @Override
    
protected Template handleRequest(HttpServletRequest request,
            HttpServletResponse response, Context ctx) 
throws Exception {
        ctx.put(
"username""张三");
        ctx.put(
"password""123456789");
        ctx.put(
"age""20");
        ctx.put(
"address""陕西西安"); 
        ctx.put(
"blog""http://blogjava.net/sxyx2008");
        
        List
<Employee> list=new ArrayList<Employee>();
        list.add(
new Employee(1,"张三","陕西西安",18,new Department(1,"软件研发部1")));
        list.add(
new Employee(2,"张三","陕西西安",19,new Department(2,"软件研发部2")));
        list.add(
new Employee(3,"张三","陕西西安",20,new Department(3,"软件研发部3")));
        list.add(
new Employee(4,"张三","陕西西安",21,new Department(4,"软件研发部4")));
        list.add(
new Employee(5,"张三","陕西西安",22,new Department(5,"软件研发部5")));
        list.add(
new Employee(6,"张三","陕西西安",23,new Department(6,"软件研发部6")));
        list.add(
new Employee(7,"张三","陕西西安",24,new Department(7,"软件研发部7")));
        list.add(
new Employee(8,"张三","陕西西安",25,new Department(8,"软件研发部8")));
        list.add(
new Employee(9,"张三","陕西西安",26,new Department(9,"软件研发部9")));
        list.add(
new Employee(10,"张三","陕西西安",27,new Department(10,"软件研发部10")));
        
        ctx.put(
"list", list);
        
//调用父类的方法getTemplate()
        return getTemplate("demo.vm""gbk");
    }
    
}
继承org.apache.velocity.tools.view.servlet.VelocityViewServlet,覆写setContentType和handleRequest方法,其中setContentType用于设置浏览器的响应,handleRequest处理用户的请求,返回Template,我们调用父类中的getTemplate()方法返回
在WEB-INF目录下创建一vm目录,用于存放模板文件
在WEB-INF目录下创建velocity.properties(名字可以任意取)
内容为
resource.loader = webapp  
webapp.resource.loader.
class = org.apache.velocity.tools.view.servlet.WebappLoader
webapp.resource.loader.path
=/WEB-INF/vm/  
input.encoding
="gbk"
output.encoding
="gbk"
resource.loader = webapp 加载方式为webapp
webapp.resource.loader.class = org.apache.velocity.tools.view.servlet.WebappLoader    webapp方式加载处理类
webapp.resource.loader.path=/WEB-INF/vm/   模板文件目录
input.encoding="gbk"  输入字符编码
output.encoding="gbk"  输出字符编码

配置web.xml
<servlet>
        
<servlet-name>customerVelocityServlet</servlet-name>
        
<servlet-class>com.velocity.servlet.CustomerVelocityServlet</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>customerVelocityServlet</servlet-name>
        
<url-pattern>/customerVelocityServlet</url-pattern>
    
</servlet-mapping>

<init-param>
   <param-name>org.apache.velocity.properties</param-name>
   <param-value>/WEB-INF/velocity.properties</param-value>
</init-param>
加载自定义的velocity.properties

demo.vm
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
 
<HEAD>
  
<TITLE> velocity </TITLE>
 
</HEAD>
