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，该问题是由于类文件的主要版本不受支持导致的。具体地，你的类文件的主要版本为64，而当前使用的Spring框架版本不支持该类文件版本。\n\n解决此问题的方法是更新Spring框架的版本，以支持类文件的主要版本为64。你可以在项目的pom.xml文件中将Spring框架的版本更新为兼容类文件版本64的版本。\n\n在pom.xml文件中，找到Spring框架的依赖项，例如：\n\nxml\n<dependency>\n <groupId>org.springframework</groupId>\n <artifactId>spring-context</artifactId>\n <version>5.1.8.RELEASE</version>\n</dependency>\n\n\n将版本号更新为兼容类文件版本64的版本，例如：\n\nxml\n<dependency>\n <groupId>org.springframework</groupId>\n <artifactId>spring-context</artifactId>\n <version>5.3.9</version>\n</dependency>\n\n\n保存pom.xml文件后，重新构建和运行应用程序，应该就能够解决该问题了。
