在Java代码中通过Spring的依赖注入来获取mysql数据源位置。 这个如何获取内容：根据错误信息，问题可能是由于使用了不支持的Java类文件版本导致的。要解决这个问题，可以尝试以下几个步骤：
-
检查Java版本：确认你使用的Java版本是否与项目要求的版本一致。可以使用命令
java -version来查看当前的Java版本。 -
更新Java版本：如果你的Java版本过低，可以尝试升级到支持项目要求的版本。你可以从Oracle官方网站或者OpenJDK网站下载最新的Java版本。
-
检查项目配置：确认项目中使用的Java类文件版本是否与你的Java版本一致。你可以在项目的构建配置文件中查看或者通过IDE的设置来确认。
-
检查依赖库版本：如果项目使用了第三方库或框架，确保你使用的是与你的Java版本兼容的最新版本。可以查看库或框架的文档或官方网站来获取相关信息。
-
清理和重建项目：尝试清理项目并重新构建，以确保所有的依赖都正确加载和编译。
如果上述步骤都没有解决问题，建议提供更多关于你的项目和环境的信息，以便更好地帮助你解决问题。
