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
解决方案
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 { }}
