研究方向
The issue is in FileDataSourceProperties.preCheck where a classpath resource is accessed using absolute path resolution, which fails inside a JAR. Investigate using Spring's ResourceLoader to obtain an InputStream instead of a File. Look at other Spring components handling classpath resources for patterns. The fix is likely in the preCheck method to use `Resource.getInputStream()` instead of `File`.
