    TiglibAction中的代码:

    package com.yulin.struts;

     

    import java.util.Date;

    import javax.servlet.http.HttpServletRequest;

    import javax.servlet.http.HttpServletResponse;

    import org.apache.struts.action.Action;

    import org.apache.struts.action.ActionForm;

    import org.apache.struts.action.ActionForward;

    import org.apache.struts.action.ActionMapping;

     

    public class TiglibAction extends Action {

    @Overridepublic ActionForward execute(ActionMapping mapping, ActionForm form,    HttpServletRequest request, HttpServletResponse response)    throws Exception {   //输出普通字符串   request.setAttribute("string", "输出普通string");   //输出html文件   request.setAttribute("html", "<font color='red'>输出html文件</font>");   //输出date   request.setAttribute("date", new Date());   //输出number   request.setAttribute("number", 12345.67);   //输出User   Group g = new Group();   g.setName("China");   User u = new User();   u.setUsername("LinZhang");   u.setAge(23);   u.setGroup(g);   request.setAttribute("user", u);     return mapping.findForward("success");   }

    }

     

    User类代码:

    package com.yulin.struts; public class User {private String username;private int age;private Group group;public String getUsername() {   return username;}

    public void setUsername(String username) {   this.username = username;}

    public int getAge() {   return age;}

    public void setAge(int age) {   this.age = age;}

    public Group getGroup() {   return group;}

    public void setGroup(Group group) {   this.group = group;}}

     

     

    Group类代码:

    package com.yulin.struts;

     

    public class Group {    private String name;

        public String getName() {       return name;}

     

    public void setName(String name) {   this.name = name;}}

     

     

    对应的jsp页面代码:

    <%@ page language="java" contentType="text/html; charset=GB18030" pageEncoding="GB18030"%><%@ taglib prefix="bean" uri="http://struts.apache.org/tags-bean"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=GB18030"><title>测试Beanwrite标签</title></head><body><li>测试Beanwrite标签</li><hr>普通string输出:<br>string(jsp):<%=request.getAttribute("string") %><br>string(taglib):<bean:write name="string"/><hr>输出html文件:<br>html(default):<bean:write name="html"/><br>html(filter="true"):<bean:write name="html" filter="true"/><br>html(filter="false"):<bean:write name="html" filter="false"/><br><hr>输出date:<br>date(default):<bean:write name="date"/><br>date(format="yy-MM-dd HH:mm:ss"):<bean:write name="date" format="yy-MM-dd HH:mm:ss"/><br><hr>输出number:<br>number(default):<bean:write name="number"/><br>number(format="###,###.###"):<bean:write name="number" format="###,###.###"/><br>number(format="###,###.000"):<bean:write name="number" format="###,###.000"/><br><hr>输出User:<br>Name:<input type="text" value=" <bean:write name="user" property="username"/> " ><br>Age:<input type="text" value=" <bean:write name="user" property="age"/> "><br>Group:<input type="text" value=" <bean:write name="user" property="group.name"/> "><br></body></html>
