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，问题出现在类文件的版本不受支持。错误信息中显示了 "Unsupported class file major version 64"，这意味着类文件的主要版本是 64，而当前的环境不支持这个版本。
解决方法是将类文件的版本降低到支持的版本。可以通过以下步骤操作：
- 确认当前使用的 JDK 版本是否支持类文件的主要版本 64。你可以在命令行中输入
java -version来查看 JDK 版本。如果版本过低，升级 JDK 版本到支持的版本。 - 检查项目中是否有其他依赖或插件会引入类文件的版本 64。可以尝试更新这些依赖或插件到支持的版本。
- 如果项目中没有其他依赖或插件引入类文件的版本 64，那么可能是因为你使用了不兼容的编译器编译项目。尝试使用与当前环境兼容的编译器重新编译项目。
- 如果以上步骤都没有解决问题，可以尝试在项目的构建文件（如 pom.xml 或 build.gradle）中指定编译器的源和目标版本，确保与当前环境兼容。
请注意，如果你不确定如何操作，可以参考项目文档或咨询项目维护者获取更详细的指导。
