问题描述
在加载我的应用程序 spring 上下文时，我收到以下错误(仅在 Linux 机器上，在 Windows 上似乎以某种方式工作):
When loading my app spring context, I am getting the following error (only on Linux machine, on Windows seem to work somehow):
无法读取架构文档'http://www.springframework.org/schema/tool/spring-tool-4.1.xsd',因为1) 找不到文件；2)文件不能读;3) 文档的根元素不是 xsd:schema.
堆栈跟踪如下:

知道这是为什么吗?
推荐答案
问题几乎肯定是 Spring 库版本问题.
The problem is almost certainly a Spring library version issue.
确保没有任何冲突的 jars(不同的 spring版本)在类路径上.如果你使用 spring 3.0 应该没有大胖 spring.jar (这是 spring 2.5 及之前).接下来如果你是创建一个包含所有包的 uber jar 确保你复制xsd 文件也是.
