Question

spring mvc 页面取不到 request model 中的值

public String getSysUser(HttpServletRequest request, HttpServletResponse response, Model model, Writer writer) throws ControllerException {
request.setAttribute("aaa", "gaga");
model.setAttribute("bbb",client);//client 实体类
return "/systemmanage/user/v006";}

在v006.jsp中
<input id="a" name="a" value=<%=request.getAttribute("aaa") %> size="22" />
取得的值是空
<input id="a" name="a" value='${bbb.name}'size="22" />
取不到值

页面取不到值，求大神解释啊
