Eclipse错误中的Struts2 MVC Maven Java项目

时间：2017-01-22 13:55:46

标签： eclipse maven jsp model-view-controller struts2

我正在使用Struts2 MVC框架创建一个maven项目。我收到以下错误： org.apache.jasper.JasperException：找不到Struts调度程序。这通常是由于使用没有关联过滤器的Struts标记引起的。 Struts标记仅在请求通过其servlet过滤器时可用，该过滤器初始化此标记所需的Struts调度程序。 - [未知位置]

根本原因：无法找到Struts调度程序。这通常是由于使用没有关联过滤器的Struts标记引起的。 Struts标记仅在请求通过其servlet过滤器时可用，该过滤器初始化此标记所需的Struts调度程序。 - [未知位置]

Stacktrace:] with root cause
The Struts dispatcher cannot be found.  This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]
