调度程序初始化失败。 java.lang.ClassNotFoundException：org.apache.struts2.views.gxp.inject.InjectedObjectContainer

Question

我正在使用Struts 2.3.14.2 jar，但是当我创建简单的应用程序时，我收到以下错误/异常。 我几乎完成了一切。 我在类路径中添加了几乎所有的jar。 但仍然得到这个例外。

我错过了什么吗？

Answer 1

如果您没有使用GXP插件，请将其从类路径中删除。 引用的类是org.apache.struts2.views.gxp.inject.InjectedObjectContainer在分发中不存在。 但是如果需要，您可以从SVN存储库下载它。

Answer 2

您不得使用插件库，除非：

1. 他们实际上是需要的; 有些人从根本上改变了S2的行为。
2. 他们的依赖性得到满足; 一些插件需要额外的库。
3. 他们的版本与S2核心库版本相匹配; 混合和匹配版本可能会失败。

使用Maven或等效解决版本和依赖性问题。

仅使用您的应用程序所需的插件可以解决其他问题。
