前台页面获取servlet传过来的数据

servlet中的代码：

public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		
		
		RequestDispatcher dispatcher = null;
		ServletContext servletContext = getServletContext();
		LinkDAO linkDAO=LinkDAOFactory.getLinkDAOInstance();
		List<Link> links=linkDAO.findAllLink();
		request.setAttribute("LinkList", links);
		dispatcher=servletContext.getRequestDispatcher("index.jsp");
                dispatcher.forward(request, response);
	}

 

这个servlet中的从数据库中获取的link列表需要在前台显示出来。前台页面可以用jstl标签配合EL标签的遍历标签来读取

<c:forEach items="${requestScope.LinkList}" var="link">
	<li><a href="#">${link.title}</a></li>
</c:forEach>
