Question

我正在尝试使用bean来显示预定义的消息，我创建了以下文件，但是当我输入< me时，它会遇到以下错误：自动代码生成器未显示<message - resources>标记!!!!

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]

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]

        </action>
    </package>

</struts-config>

register.jsp：

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

    <div id="Header">
        <bean:message key="welcome.loggedin"/>
    </div>

messages.properties：

# -- welcome --
welcome.loggedin=You are logged in.
welcome.heading=Struts Applications in Netbeans!
welcome.message=It's easy to create Struts applications with NetBeans.

我想问题是我的jar文件

commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar

Answer 1

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

这是Struts2 documentation page about i18n。

Answer 2

<bean:message key=标记是Struts1标记，在Struts2中它被<s:text name=替换。除非你没有足够的理由来运行这两个框架，否则你不应该使用Struts1标签。

Struts 2无法使用bean：message
