目錄結構
點我下載工程代碼
倆實體類不用說了
看CustomerVelocityServlet類
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{
//設置返回視圖為text/html編碼為gbk
@Override
protected void setContentType(HttpServletRequest request,
HttpServletResponse response) {
response.setContentType("text/html;charset=gbk");
}
//處理請求
@Override
protected Template handleRequest(HttpServletRequest request,
HttpServletResponse response, Context ctx) throws Exception {
ctx.put("username", "張三");
ctx.put("password", "123456789");
ctx.put("age", "20");
ctx.put("address", "陜西西安");
ctx.put("blog", "http://blogjava.net/sxyx2008");
List<Employee> list=new ArrayList<Employee>();
list.add(new Employee(1,"張三","陜西西安",18,new Department(1,"軟件研發部1")));
list.add(new Employee(2,"張三","陜西西安",19,new Department(2,"軟件研發部2")));
list.add(new Employee(3,"張三","陜西西安",20,new Department(3,"軟件研發部3")));
list.add(new Employee(4,"張三","陜西西安",21,new Department(4,"軟件研發部4")));
list.add(new Employee(5,"張三","陜西西安",22,new Department(5,"軟件研發部5")));
list.add(new Employee(6,"張三","陜西西安",23,new Department(6,"軟件研發部6")));
list.add(new Employee(7,"張三","陜西西安",24,new Department(7,"軟件研發部7")));
list.add(new Employee(8,"張三","陜西西安",25,new Department(8,"軟件研發部8")));
list.add(new Employee(9,"張三","陜西西安",26,new Department(9,"軟件研發部9")));
list.add(new Employee(10,"張三","陜西西安",27,new Department(10,"軟件研發部10")));
ctx.put("list", list);
//調用父類的方法getTemplate()
return getTemplate("demo.vm", "gbk");
}
}
繼承org.apache.velocity.tools.view.servlet.VelocityViewServlet，覆寫setContentType和handleRequest方法,其中setContentType用于設置瀏覽器的響應,handleRequest處理用戶的請求,返回Template,我們調用父類中的getTemplate()方法返回
在WEB-INF目錄下創建一vm目錄,用于存放模板文件
在WEB-INF目錄下創建velocity.properties(名字可以任意取)
內容為
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 加載方式為webapp
webapp.resource.loader.class = org.apache.velocity.tools.view.servlet.WebappLoader webapp方式加載處理類
webapp.resource.loader.path=/WEB-INF/vm/ 模板文件目錄
input.encoding="gbk" 輸入字符編碼
output.encoding="gbk" 輸出字符編碼
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>
加載自定義的velocity.properties
demo.vm
