配置 org.apache.struts2.tiles.StrutsTilesListener 类的应用程序侦听器时出错 [英] Error configuring application listener of class org.apache.struts2.tiles.StrutsTilesListener

问题描述

我正在尝试将 Tiles3.0.3 与 Struts2 集成，但我收到了 java.lang.NoClassDefFoundError 和 java.lang.ClassNotFoundException.

I am trying to integrate Tiles3.0.3 with Struts2, but I am getting java.lang.NoClassDefFoundError and java.lang.ClassNotFoundException.

这是我的 web.xml

Here is my web.xml

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

    </session-timeout>
</session-config>
<welcome-file-list>
    <welcome-file>example/HelloWorld.jsp</welcome-file>
</welcome-file-list>
</web-app>

这是我的tiles.xml

And here is my tiles.xml

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE tiles-definitions PUBLIC  "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
  "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">

<tiles-definitions>
<definition name="baseLayout" template="/baseLayout.jsp">

  <put-attribute name="body"   value="/body.jsp"/>
  <put-attribute name="footer"   value="/footer.jsp"/>
</definition>
<definition name="tiger" extends="baseLayout">
  <put-attribute name="title"  value="Tiger"/>
  <put-attribute name="body"   value="/tiger.jsp"/>      
</definition>

<definition name="lion" extends="baseLayout">
  <put-attribute name="title"  value="Lion"/>
  <put-attribute name="body"   value="/lion.jsp"/>      
</definition>

</tiles-definitions>

这些是我得到的错误

请帮帮我.

推荐答案

你需要在你的 web-inf/classes 中有瓷砖 jar.

You need to have tiles jar in your web-inf/classes.

如果您的项目启用了 maven，请使用以下内容:

If your project is maven enabled use below:

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-tiles-plugin</artifactId>
    <version>2.3.16.1</version>
</dependency>

或者手动下载struts-tiles插件和tiles插件jars

Or download struts-tiles plugin and tiles plugin jars manualy
