Answer 1

如果你有......

包括所有必要的罐子
正确配置构建路径
在部署程序集中添加所有内容正确。

然后你得到＆＃34; java.lang.ClassNotFoundException：org.apache.struts2.dispatcher.FilterDispatcher＆＃34;错误，那么你可能会在错误的情况下做。

<强>溶液

检查您的struts2-core-x.x.jar版本。

- ＆gt;如果是struts2-core- 2.5 .jar，请将web.xml中的过滤器类标记值更改为

<filter-class>
     org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
  </filter-class>

- ＆gt;如果是struts2-core- 2.1.3 .jar，请将web.xml中的过滤器类标记值更改为

<filter-class>
     org.apache.struts2.dispatcher.FilterDispatcher
  </filter-class>

自Struts 2.1.3起，不推荐使用FilterDispatcher。如果您使用的是旧版本，请使用上述解决方案。

- ＆gt;如果是struts2-core- 2.3.X .jar，请将web.xml中的过滤器类标记值更改为

<filter-class> 
    org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>

所有这些背后的原因是struts 2控制器被放置在不同版本的struts2-core jar中的不同位置，有时它们被不同的名称调用，如 2.1.3 中所示。< / p>

谢谢，

Answer 2

Struts2在执行程序之前需要一定数量的jar文件。确保您的编辑工具中包含以下内容：

commons-logging-x.x.jar
freemarker-x.x.jar
xwork-x.x.jar
struts2-core-x.x.jar
ognl-x.x.jar

普通伐木罐可能会丢失。

查看struts2 lib文件以获取这些jar文件。：）

Answer 3

如果您正在使用Eclipse，那么仅在Java Build Path中添加所需的库将不起作用。您必须在Deployment Assembly中再次添加这些库。右键单击项目＆gt;＆gt;属性＆gt;＆gt;选择部署Assemlby。单击Add ..按钮添加所需的Java Build Path条目。

Answer 4

检查您的Web应用程序的类路径中是否有struts2.jar。

Answer 5

问题仅在于您的类路径设置，因为您的类路径中包含所有jar。如果你正在使用eclipse，只需从类路径中删除所有jar，然后再从头开始构建类路径。它会起作用

Answer 6

第一步看下面的tomcat webapp lib文件夹下面的jar包没有副本，

Answer 7

这对我有用：

将所有必要的jar文件复制到 WebContent＆gt; WEB-INF＆gt; lib 文件夹
确保您添加了 commons-lang3-3.1 和 struts2-core-2.3.16.3

Answer 8

Struts2使用了很多依赖的jar，将它们放在WEB-INF / lib文件夹中。这种组合对我有用。我将它们部署在Tomcat-7.0.6或7.0.57

上

我用过的兼容罐子： Struts2的核心 - 2.3.4.jar 公地文件上传-1.3.1.jar 公地IO-2.4.jar 共享记录-1.1.3.jar 共享记录-API-1.1.jar freemarker的-2.3.23.jar OGNL-3.1.4.jar XWork的核心 - 2.3.4.jar javaassist-3.2.0-GA.jar 公地lang3-3.4.jar

java.lang.ClassNotFoundException：org.apache.struts2.dispatcher.FilterDispatcher
