Answer 1

div class="bar">
 <div class="menulink"><a href="index.html">Home</a></div>
            <div class="menulink"><a href="savingsAccount.jsp?username=<%=request.getParameter("uname")%>">Savings</a></div>
            <div class="menulink"><a href="#">FAQ</a></div>
            <div class="menulink"><a href="#">Help</a></div>
 </div>
</div>

在savingsAccount.jsp中，您可以使用以下方式获取此参数：

String uname = request.getParameter("username");

Answer 2

在jsp页面中

<a href="viewProfile?email=<%=request.getParameter("email")%> " >View Profile</a>

在Java页面中

   @RequestMapping("/viewProfile")
    public void viewUser(HttpServletRequest req, HttpServletResponse res){

        String email = req.getParameter("email");
        System.out.println(email);
    }

将锚标记中的值传递给另一个jsp
