Java Session和Cookie

一、Session

1.session配置：web.xml 中<web-app>下session存活时间(min分钟)

<session-config>
    <session-timeout>30</session-timeout>
</session-config>

2.session对象获得：

Map<String, Object> session = (Map<String, Object>) ActionContext.getContext().getSession();

//对比Request对象的获得;
Map<String, Object> request = (Map<String, Object>) ActionContext.getContext().get("request");

HttpServletRequest requests = ServletActionContext.getRequest();
Cookie[] cookies = requests.getCookies();  
 HttpSession sessions = requests.getSession();

//struts1中Session通过request获得
//HttpSession session = request.getSession(true);
