Spring配置文件：如果使用Spring框架，可以将mysql数据源位置写在Spring配置文件中，例如：\nxml\n<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">\n <property name="url" value="jdbc:mysql://localhost:3306/mydatabase" />\n <property name="username" value="root" />\n <property name="password" value="123456" />\n</bean>\n\n在Java代码中通过Spring的依赖注入来获取mysql数据源位置。\n这个如何获取内容：根据错误日志，问题出在文件的类版本不被支持。错误信息中提到了"Unsupported class file major version 64"，这意味着你正在尝试运行一个使用了不被当前Java版本支持的类文件。\n\n解决这个问题的方法是使用与你当前Java版本兼容的类文件。根据错误日志中给出的文件路径，你正在尝试运行的类文件是PanApplication.class，位于com.bjpowernode.pan包中。\n\n首先，确认你当前使用的Java版本是否与该类文件兼容。如果你的Java版本过低，可以尝试升级到与类文件兼容的版本。\n\n如果你已经使用了与类文件兼容的Java版本，那么可能是你的项目中包含了不兼容的类文件。可能的原因是你的项目中包含了不同Java版本的依赖项。你可以尝试更新这些依赖项，确保它们与你的Java版本兼容。\n\n另外，还可以检查你的项目构建配置文件（例如pom.xml或build.gradle）中是否指定了正确的Java版本。确保配置文件中的Java版本与你当前使用的Java版本一致。\n\n如果你使用的是IDE（如IntelliJ IDEA或Eclipse），还可以尝试清理和重新构建项目，以确保所有的类文件都是与当前Java版本兼容的。\n\n如果上述方法都没有解决问题，可以尝试使用其他版本的Spring框架，可能是当前版本的Spring框架不兼容你的Java版本。\n\n总之，解决这个问题的关键是确保你的项目中的所有类文件都是与当前Java版本兼容的。根据错误日志提供的信息进行排查，更新或更换不兼容的类文件，确保项目能够正确运行。
