java 里 如何重写 httpsession 的setAttribute方法 来设置session

java 里 如何重写 httpsession 的setAttribute方法 来设置session

Answer 1

这是我写的一个setvlet，里面就是设置session值 供楼主参考public class Session extends HttpServlet {
public void init(ServletConfig config) throws ServletException {
super.init(config);
}

public void doPost(HttpServletRequest request,HttpServletResponse response)
throws IOException,ServletException{

PrintWriter out = response.getWriter();

//获取JSP页面传来的姓名值
String name1 = request.getParameter("name");
String name = new String(name1.getBytes("ISO-8859-1"));
//将姓名放入session
HttpSession session = request.getSession(true);
session.setAttribute("name", name);
}

public void doGet(HttpServletRequest request,HttpServletResponse response)
throws IOException,ServletException{
doPost(request,response);
}

public void destroy(){

}
}

Answer 2

写一个类继承httpsession ，然后重写setAttribute方法，以后调用自己写的类即可

Answer 3

HttpSession hs=req.getSession(true);
hs.setMaxInactiveInterval(10);
hs.setAttribute("pass", u);

Answer 4

先继承再重写啊。
