意外异常从 class 路径资源解析 XML 文档
Unexpected exception parsing XML document from class path resource
我在初始化 spring 上下文时遇到此异常。
我可以确认我只使用了一个 spring 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 文件正在另一个分支中工作。

在我看来，即使您只使用一个版本，我也认为存在内部混淆依赖版本...这导致依赖之间存在困难和冲突。
确保检查了本地所有依赖项的版本。无论如何，我仍在研究更好的答案。
下面是我的应用的耳朵结构
'sample.jar'
'firstWar'
'secondWar'
在 sample.jar 文件中，我定义了正在从 'secondWar.war' 项目初始化的 bean。这两个项目即 sample.jar 和 'secondWar.war' 具有相同的依赖性，即 'spring-webmvc' 这导致了混乱。从 'secondWar.war' 中删除了此依赖项，它现在可以正常工作了**
