spring - 从类路径资源解析 XML 文档时出现意外异常

问题描述

我在初始化 spring 上下文时遇到了这个异常。

我可以确认我只使用了一个弹簧版本，即 5.3.3。

当我删除时，

<context:annotation-config />
<context:component-scan base-package="com" />

从 xml 然后没有与此相关的错误。同样的 applicationContext.xml 文件也在另一个分支中工作。

解决方案

在我看来，即使您只使用一个版本，我认为存在内部混淆依赖版本......这导致了依赖关系之间的困难和冲突。

确保检查了本地拥有的所有依赖项版本。无论如何，我仍在研究更好的答案。
