request.getSession().setAttribute()有什么问题 [英] What's wrong about request.getSession().setAttribute()

问题描述

我用来在*.java和*.jsp之间传递数据，因为这是一个MVC框架，所以它将首先通过*.java.所以我用request.getSession().setAttribute("test", "01010101010")保存值，然后在*.jsp中使用request.getSession().getAttribute("test")获取值. 但是它始终会返回一个奇怪的字符串"682342348".

I use to pass data between *.java and *.jsp, since this is a MVC framework, it will go by the *.java first. so i used request.getSession().setAttribute("test", "01010101010") to save the value, and then in *.jsp, use request.getSession().getAttribute("test") to get value. But it returns a strange string "682342348" all the time.

推荐答案

现在这可能是一个JavaScript问题，请尝试在alert参数的值周围添加引号.

This might be a javascript question now, try adding quotes around the value of the alert parameter.

更改此:

<script>alert(<%=request.getAttribute("test")%>);</script>

对此:

<script>alert('<%=request.getAttribute("test")%>');</script>
