现在,RegistrationSucess 页面终于显示了这个 :( 请帮助我在哪里做错了。提前致谢。
【问题讨论】:
尝试修复您的 web.xml 声明(您正在混合 2.5 和 3.0 版本)。以此为例:javahowto.blogspot.fr/2010/07/…。另外,您在哪里部署应用程序? HI JB 我将 web.xml 更改为以下,但没有运气,仍然得到相同的输出:(不知何故,EL 评估在您的设置中被禁用(我猜测 servlet 容器和 web.xml 声明的版本不匹配)。尝试添加 isELIgnored
属性,将其设置为 false 并检查
<%@ page isELIgnored="false" %>

【参考方案2】:这是从示例项目(工作)中复制的代码。只是删除了一些其他 bean 定义。
