JSP中正则表达式用法实例
本文实例讲述了JSP中正则表达式用法。分享给大家供大家参考，具体如下：
<%@ page language="java" import="java.util.*,cn.com.Person,cn.com.Adddress" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
My JSP 'El.jsp' starting page
<%
String data="assd";
request.setAttribute("data", data);
%>
${data }
<%
Person p=new Person();
p.setName("name");
request.setAttribute("person", p);
%>
${person.name}
<%
Person p2=new Person();
Adddress add=new Adddress();
add.setCity("NewYork");
p2.setAddress(add);
request.setAttribute("p2", p2);
%>
${p2.address.city}
<%
ArrayList list=new ArrayList();
list.add(new Person("wy"));
list.add(new Person("wyy"));
list.add(new Person("wyyy"));
request.setAttribute("list", list);
%>
${list[1].name }
<%
Map map=new HashMap();
map.put("1", new Person("aaaa"));
map.put("b", new Person("bbbb"));
map.put("c", new Person("cccc"));
map.put("d", new Person("dddd"));
request.setAttribute("map", map);
%>
${map.b.name}
${map['1'].name }
${pageContext.request.contextPath}
