时，它遇到以下错误，自动代码生成器不显示

<message - resources>

标签!!!!

org.apache.jasper.JasperException: 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]

Answer 1

<bean:message key=

标签是一个Struts1标签，在Struts2中它被替换为

<s:text name=

。除非您没有足够的理由运行这两个框架，否则您不应该使用 Struts1 标签。

Answer 2

您在 Struts 2 应用程序中使用 Struts 1 标签。不。 Struts 1 和 Struts 2 是两个完全不同的 Web 框架。
