webwork中没有cookie的映射,只有session的映射. 参考了moxie的cookie拦截器,自己写了一个拦截器,不知道是不是能用 :P
拦截器代码如下:
package com.cnscud.util.interceptor;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.cnscud.util.WebCookies;
import com.opensymphony.webwork.ServletActionContext;
import com.opensymphony.xwork.ActionInvocation;
import com.opensymphony.xwork.interceptor.AroundInterceptor;
import com.opensymphony.xwork.util.OgnlValueStack;
/**
* Cookie拦截器,在Action里增加getWebCookies
*
* 参考moxie的cookie测试拦截器.
*
* @author scud 2004.10
*
*/
public class WebCookiesInterceptor extends AroundInterceptor
{
protected void after(ActionInvocation arg0, String arg1) throws Exception
{
}
protected void before(ActionInvocation arg0) throws Exception
{
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest();
Cookie[] cookies = request.getCookies();
if (cookies != null && cookies.length > 0)
{
final OgnlValueStack stack = ServletActionContext.getContext().getValueStack();
WebCookies aWCs = new WebCookies(request,response,cookies);
stack.setValue(WebCookies.KEY_WEBCOOKIES,aWCs);
}
}
}
WebCookies的代码如下:
package com.cnscud.util;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.*;
/*
* WebCookies类
*
* 写一个cookie类来代替Cookie就不用依赖javax.servlet.http了 (TODO)
*
* @author scud 2004.10
*
*/
public class WebCookies
{
/** ValueStack里面的键值 */
public static final String KEY_WEBCOOKIES = "webCookies";
private HttpServletRequest request;
private HttpServletResponse response;
private Cookie[] cookies;
private Map cookieMap = new HashMap(20);
/**
* 构造函数
*
* @param request
* @param response
* @param cookies
*/
public WebCookies(HttpServletRequest request, HttpServletResponse response,
Cookie[] cookies)
{
this.request = request;
this.response = response;
setCookies(cookies);
}
/**
* 设置Cookie数组
*
* @param cookies
*/
public void setCookies(Cookie[] cookies)
{
cookieMap.clear();
this.cookies = cookies;
for (int i = 0; i < cookies.length; i++)
{
Cookie acookie = cookies[i];
cookieMap.put(acookie.getName(), acookie);
}
}
/**
* 得到cookie数组
*
* @return cookie的数组
*/
public Cookie[] getCookies()
{
return cookies;
}
/**
* 得到某个cookie
*
* @param sKey 键名
* @return 对应的cookie
*/
public Cookie getCookie(String sKey)
{
if (null == cookieMap)
{
return null;
}
Object ac = cookieMap.get(sKey);
if (null != ac)
{
return (Cookie) ac;
}
return null;
}
public Cookie get(String sKey)
{
return getCookie(sKey);
}
public Map getCookieMap()
{
return cookieMap;
}
/**
* 添加一个cookie设置到HttpServletResponse中去
*
* @param aCookie
*/
public void addCookie(Cookie aCookie)
{
//调用response的addCookie
if (null != response)
{
response.addCookie(aCookie);
}
}
}
基础Action的代码如下: (其他action继承此Action即可)
package test;
import com.cnscud.util.WebCookies;
import com.opensymphony.xwork.ActionSupport;
public class CookieAction extends ActionSupport
{
protected WebCookies webcookies;
public void setWebCookies(WebCookies webcookies)
{
this.webcookies = webcookies;
}
public WebCookies getWebCookies()
{
return webcookies;
}
}
Xwork的配置如下,可以根据自己的需求改动,我是所有action都截取cookie
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">
<xwork>
<include file="webwork-default.xml"/>
<package name="helloWorld" extends="webwork-default">
<interceptors>
<interceptor name="webCookiesInterceptor" class="com.cnscud.util.interceptor.WebCookiesInterceptor" />
<interceptor-stack name="cookieStatck">
<interceptor-ref name="webCookiesInterceptor"/>
<interceptor-ref name="defaultStack"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="cookieStatck" />
<action name="startCookie" class="test.StartAction">
<result name="success" type="dispatcher">
<param name="location">/start.jsp</param>
</result>
</action>
<action name="resultCookie" class="test.ResultAction">
<result name="success" type="dispatcher">
<param name="location">/result.jsp</param>
</result>
</action>
</package>
</xwork>
result的页面:
<%@ page contentType="text/html;charset=UTF-8" %>
<%@ taglib uri="webwork" prefix="ww" %>
<html>
<head>
<title>My JSP 'result.jsp' result page</title>
</head>
<body>
cookie Hello:
<ww:property value="webCookies.cookieMap['Hello'].value" />
<br><br>
Cookie Hello2:
<ww:property value="webCookies.cookieMap.Hello2.value" />
<br><br>
testValue:<ww:property value="testValue" />
<br><br>
</body>
</html>
ResultAction代码如下:
package test;
import javax.servlet.http.Cookie;
public class ResultAction extends CookieAction
{
private String testValue;
public String execute() throws Exception
{
//for test
Cookie[] cs = webcookies.getCookies();
return SUCCESS;
}
public void setTestValue(String testValue)
{
this.testValue = testValue;
}
public String getTestValue()
{
return testValue;
}
}
StartAction的代码如下
package test;
import javax.servlet.http.Cookie;
public class StartAction extends CookieAction
{
public String execute() throws Exception
{
Cookie ack = new Cookie("Hello","World222");
webcookies.addCookie(ack);
return SUCCESS;
}
}
