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}
    点

希望本文所述对大家JSP程序设计有所帮助。
