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+"/";
%>


 
 
 
 
 
  
 
 
 
 
 
 <%
  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}
