初识jsp与servlet数据传输方式

1、servlet传到jspservlet端request.setAttribute("name", "user");request.setAttribute("password", "123");//传递到main.jsp页面request.getRequestDispatcher("main.jsp").forward(request, response);jsp页面<%=request.getAttribute("name") %><%=request.getAttribute("password") %>
2、jsp传到servlet通过超链接传值
<a href="FirstServ?type=one&name=name">链接</a>//在jsp中发送type的值String type = request.getParameter("type");//在servlet接受type的值String type = request.getParameter("name");表单传值
//jsp<form action="main" method="post">名称：<input type="text" name="name">密码：<input type="text" name="password"><input type="submit">
//servletString name = request.getParameter("name");String pa = request.getParameter("password");
