  • Web_Servlet和jsp页面数据交互,通过请求转发在jsp中显示数据

    1.Servlet页面代码

    /*
        实现jsp页面和sevlet页面的信息交互
     */
    @WebServlet(urlPatterns = "/aa")
    public class JspService extends HttpServlet {
        protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
            doGet(request,response);
        }
    
        protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    
            //以键值对存储数据
    
            request.setAttribute("name","张三丰");
    
            //进行页面跳转,把信息传过去
            request.getRequestDispatcher("/demojsp.jsp").forward(request,response);
    
        }
    }

    2.Jsp页面

    <%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>Title</title>
    </head>
    <body>
        <div>
            <font color="#808080"><%=request.getAttribute("name")%></font>
        </div>
    </body>
    </html>
