问题描述

我已经建立了一个项目，它是 Struts2 + Springs + JPA 的组合.

我最近遇到了 Struts2-Jquery 插件

在我的项目中使用这个插件 (struts2-jquery-plugin-3.5.1.jar) 出现错误

在此处提供了此特定错误的解决方案 作为 Struts2 DTD 问题.

执行上述链接中给出的解决方案.. 更新了我的 webapp lib 文件夹中的三个库:

  • Struts2-core-2.3.4.1
  • struts2-spring-plugin-2.3.4.1
  • xwork-core-2.3.4.1

在此更新后尝试部署时，我得到了此堆栈跟踪

谁能告诉我哪里出错了?

解决方案

您需要将 commons-lang3-3.x.jar 添加到您的类路径中，以便过滤器运行.

你必须确保你没有多个版本的 commons-lang3-x.x.jar.

commons-lang3-xxjar 和 commons-lang-xxjar 可以共存于同一个 classpath 中，因为 package 是不同的(他们是故意这样做的；)

<小时>

这是可以知道的，因为NoClassDefFoundError:

<块引用>

java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils.

主要发生在两种情况:

  • 在运行时，您没有库，
  • 或者您有两个版本的库，因此类加载器不知道选择哪个，并引发异常.

包中的lang3意味着缺少的StringUtils类来自common-lang3-*.jar，而不是common-lang-*.jar.>

I have setup a project which is a combo of Struts2 + Springs + JPA.

I recently came across the Struts2-Jquery Plugin

Using this plugin (struts2-jquery-plugin-3.5.1.jar) in my project I got an error

The solution to this particular error was given here as Struts2 DTD problem.

Acting in the solution given in the above link.. updated three libraries in my webapp lib folder:

  • Struts2-core-2.3.4.1
  • struts2-spring-plugin-2.3.4.1
  • xwork-core-2.3.4.1

When trying to deploy after this update I got this stacktrace

Can anyone give me a pointer where I am going wrong ?

解决方案

You need to add the commons-lang3-3.x.jar to your classpath for the filter to run.

You must ensure you don't have multiple versions of commons-lang3-x.x.jar too.

commons-lang3-x.x.jar and commons-lang-x.x.jar instead can coexist in the same classpath, because the package is different (they did it on purpose ;)

This can be known, because of NoClassDefFoundError:

java.lang.NoClassDefFoundError: org/apache/commons/lang3/StringUtils.

which occurs mostly in two cases:

  • at runtime, you doesn't have the library,
  • or you have two versions of the library, hence the classloader doesn't know which to pick, and raises the exception.

The lang3 in the package means that the StringUtils class missing is from common-lang3-*.jar, not from common-lang-*.jar.
