我正在尝试一个带有 struts2.3 jar 的简单 struts2 应用程序，但它给出了调度程序初始化错误

2.3 罐子包括：

commons-beanutils-1.7.0.jar
commons-chain-1.2.jar
commons-collections-3.1.jar
commons-digester-2.0.jar
commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-lang-2.5.jar
commons-logging-1.1.1.jar
commons-logging-api-1.1.jar
commons-validator-1.3.1.jar
freemarker-2.3.18.jar
ognl-3.0.4.jar
struts2-core-2.3.1.2.jar
xwork-core-2.3.1.2.jar

web.xml 是

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

  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>

struts.xml 是：

<struts>

<constant name="struts.devMode" value="true" />

<package name="/abc"  extends="struts-default">

<!-- action declarations.... -->
<action name="login" class="actions.TestLogin">
<result name="success">/WEB-INF/results/success.jsp</result>
<result name="error">/WEB-INF/results/error.jsp</result>
</action>

</package>
</struts>

异常堆栈是：

我尝试使用带有 web.xml 的 struts 2.0 jar 执行相同的应用程序

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

  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>

它是工作文件，但是使用 struts 2.3 jars 它给出了一个异常我无法弄清楚问题是什么。请提出可能是什么问题

感谢你

在您的库中维护以下版本的 jar。我想你不会遇到任何问题

antlr-2.7.6.jar
commons-beanutils-1.7.0.jar
commons-collections-3.2.jar
commons-digester.jar
commons-fileupload-1.2.2.jar
commons-io-2.4.jar
commons-lang-1.2.jar
commons-logging-1.1.jar
freemarker-2.3.16.jar
javassist-3.7.ga.jar
ognl-3.0.jar
struts2-core-2.2.3.jar
xwork-core-2.2.1.jar

伙计，您的错误堆栈跟踪本身会告诉您问题所在，请参阅堆栈跟踪中的这一行：

Caused by: java.lang.IllegalArgumentException: Javassist library is missing in classpath! Please add missed dependency!
at ognl.OgnlRuntime.<clinit>(OgnlRuntime.java:168)

这意味着缺少 javassist-3.11.0.GA.jar（或类似的）文件。添加该文件，尝试再次运行您的应用程序，然后查看它给出的其他错误。祝你好运:)

当某些 jar 丢失时会出现此错误。所以我使用您提供的 jar 测试了 struts 简单应用程序，与您定义的问题相同，但在包括这 4 个必要的 jar 之后

commons-lang3-3.1.jar
javaassist-3.11.0.GA.jar
asm-3.3.jar
asm-commons-3.3.jar

问题解决了 。

</filter>
<filter-mapping>
