org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.mybatis.spring.boot.autoconfigure.MybatisLanguageDriverAutoConfiguration] for bean with name 'org.mybatis.spring.boot.autoconfigure.MybatisLanguageDriverAutoConfiguration': problem with class file or dependent class; nested exception is java.lang.UnsupportedClassVersionError: org/mybatis/spring/boot/autoconfigure/MybatisLanguageDriverAutoConfiguration has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

这个错误通常是由于您使用的Java版本不兼容导致的。您可以尝试将您的Java版本升级到与MyBatis和Spring的依赖版本兼容的版本。

您可以在JDK官方网站上找到不同版本的Java并下载安装，或者使用版本管理工具来管理您的Java版本。

另外，您还需要确保您的应用程序正确配置了MyBatis和Spring的依赖项，并且在Spring配置文件中正确地配置了相关组件和属性。如果您需要更详细的帮助，请提供更多的信息和代码片段，以便我可以更好地帮助您解决问题。

根据您提供的错误信息，看起来是在创建名为 "borrowController" 的 bean 时出现了错误，因为无法满足它的依赖项 "borrowService"。进一步的错误消息表明，"borrowServiceImpl" 的依赖项 "medicMapper" 无法解析对 "sqlSessionTemplate" 的引用。

这可能是由于您的应用程序缺少所需的依赖项或配置文件，或者您的依赖项和配置文件存在问题。您可以检查您的代码和配置文件，确保它们正确地设置了所有必需的依赖项，并且没有任何拼写错误或语法错误。

您还可以尝试清除并重新构建您的应用程序，以确保所有依赖项都正确地安装和配置。如果问题仍然存在，请检查您的 MyBatis 配置文件和映射文件，确保它们正确地配置了所有数据库连接和查询。您还可以尝试查看其他错误消息或日志，以获取更多有关问题的信息。

你的问题是：为什么在初始化上下文时遇到了异常，并且报错说无法加载MySQL驱动类com.mysql.cj.jdbc.Driver？

这个问题可能是由于以下几个原因导致的：

1. 缺少MySQL驱动依赖：请确保在你的项目中包含了正确的MySQL驱动依赖。你可以在项目的构建配置文件（比如pom.xml）中添加如下依赖：

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.26</version>
</dependency>

请根据你使用的MySQL版本选择合适的驱动版本。

2. 驱动类名错误：请检查你的配置文件中是否正确指定了MySQL驱动类名。一般情况下，MySQL 8使用的驱动类名是`com.mysql.cj.jdbc.Driver`，而不是过时的`com.mysql.jdbc.Driver`。

请检查以上两个方面，如果问题仍然存在，请提供更多的错误信息和相关配置，以便我可以给出更具体的解决方案。
