JSP页面传值到JSP页面

传值页面，和传入服务器一样的JSP页面没有区别

<!-- book从Servlet获得-->
<td>
    <a href="update.jsp?bookid=${book.bookid}&bookname=${book.bookname }&bookprice=${book.bookprice}&bookimg=${book.bookimg}">修改</a>
</td>

需要获得值得JSP页面，只需要在以前的ER表达式前面加上   param

<tr>
			<td><input readonly="true" type="text" name="bookid" value="${param.bookid }"></td>
			<td><input type="text" name="bookname" value="${param.bookname}"></td>
			<td><input type="text" name="bookprice" value="${param.bookprice}"></td>
			<td><input type="text" name="bookimg" value="${param.bookimg}"></td>
			<td><input type = "submit" value="修改"></td>
</tr>
