public class AllServlet extends HttpServlet {
String title = "title...";
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.getRequestDispatcher("/themes/tuzuan/all.jsp").forward(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
}
这个 title 在 all.jsp 怎么获取显示到网页上
需要在request中设置相应的属性才能在页面接收到
public class AllServlet extends HttpServlet {
String title = "title...";
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setAttribute("title", title);
request.getRequestDispatcher("/themes/tuzuan/all.jsp").forward(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
}
