<bean:write>

 

对Struts中的BeanWrite标签做下测试（具体过程可以参见尚学堂的视频）

前提：好像必须要导入struts的国际化标签，有待验证。

第一步：添加BeanWriteTestAction类

Java代码 
  1. package com.bjsxt.struts; 
  2. /**
  3. * 测试BeanWrite
  4. */ 
  5. publicclass BeanWriteTestAction extends Action { 
  6.     public ActionForward execute(ActionMapping mapping, ActionForm form, 
  7.             HttpServletRequest request, HttpServletResponse response) 
  8.             throws Exception { 
  9.         //普通属性 
  10.         request.setAttribute("hello", "Hello World"); 
  11.          
  12.         //html文本 
  13.         request.setAttribute("bj", "<font color='red'>北京欢迎您</font>"); 
  14.          
  15.         //日期 
  16.         request.setAttribute("today", new Date()); 
  17.          
  18.         //数字 
  19.         request.setAttribute("n", 123456.987); 
  20.          
  21.         //结构 
  22.         Group group = new Group(); 
  23.         group.setName("尚学堂"); 
  24.          
  25.         User user = new User(); 
  26.         user.setUsername("张三"); 
  27.         user.setAge(18); 
  28.         user.setGroup(group); 
  29.          
  30.         request.setAttribute("user", user); 
  31.          
  32.         return mapping.findForward("success"); 
  33.     } 
  34.  
  35. }  
package com.bjsxt.struts;
/**
 * 测试BeanWrite
 */
public class BeanWriteTestAction extends Action {
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		//普通属性
		request.setAttribute("hello", "Hello World");
		
		//html文本
		request.setAttribute("bj", "<font color='red'>北京欢迎您</font>");
		
		//日期
		request.setAttribute("today", new Date());
		
		//数字
		request.setAttribute("n", 123456.987);
		
		//结构
		Group group = new Group();
		group.setName("尚学堂");
		
		User user = new User();
		user.setUsername("张三");
		user.setAge(18);
		user.setGroup(group);
		
		request.setAttribute("user", user);
		
		return mapping.findForward("success");
	}

}

 

第二步：添加测试的jsp页面（beanwrite.jsp）

Html代码
  1. <%@ page language="java"contentType="text/html; charset=GB18030" 
  2.     pageEncoding="GB18030"%> 
  3. <%@ taglib prefix="bean"uri="http://struts.apache.org/tags-bean"%>

  7. <metahttp-equiv="Content-Type"content="text/html; charset=GB18030">

<%@ page language="java" contentType="text/html; charset=GB18030"

<%@ taglib prefix="bean" uri="http://struts.apache.org/tags-bean"%>
