webwork的拦截器不能取cookie??
最近发现一个问题,webwork在拦截器里用HttpServletRequest是获取不到cookie的,但是在action里却能够取到cookie。
情况是这样:
拦截器的代码:
public String intercept(ActionInvocation arg0){
String result = null;
HttpServletRequest request = ServletActionContext.getRequest();
Cookie cookies[] = request.getCookies();
Cookie sCookie = null;
String value = null;
if (cookies != null) {
for (int i = 0; i < cookies.length; i++) {
sCookie = cookies[i];
if (sCookie.getName().equals("cookieName")) {
value = sCookie.getValue();
}
}
before(arg0);
result = arg0.invoke();
after(arg0, result);
return result;
}
这里的value的结果是null。
但是在action里,用同样的代码是可以获取到值的:
public String execute(){
javax.servlet.http.Cookie cookies[] = request.getCookies();
javax.servlet.http.Cookie sCookie = null;
String value = null;
if (cookies != null) {
for (int i = 0; i < cookies.length; i++) {
sCookie = cookies[i];
if (sCookie.getName().equals("cookieName")) {
value = sCookie.getValue();
}
}
}
return SUCCESS;
}
此时的value是可以取到值的。
设置cookie的代码:
Cookie cookie_name =new Cookie("cookieName",value);
cookie_name.setPath("/");
cookie_name.setMaxAge(365*24*60*60);
response.addCookie(cookie_name);
难道webwork拦截器里的request处理问题?或者我这种拦截器里获取cookie的写法有问题?

可以的我这边测试是可以的,是不是你配置的问题
1、STRTUS有自定义的COOKIE拦截器,你可以参考下它的实现
org.apache.struts2.interceptor.CookieInterceptor
2、以下是我的测试代码
Java code
struts.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<constant name="struts.devMode " value="true"></constant>
<constant name="struts.objectFactory" value="org.apache.struts2.impl.StrutsObjectFactory"></constant>
<package name="zhangyz" extends="struts-default" namespace="/zhangyz">

<result name="success">/index.jsp</result>
</action>
</package>
</struts>
