Spring Boot 异常: UnsatisfiedDependencyException - 找不到 mybatis-config.xml 文件

Spring Boot 应用中出现“org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'sqlSessionFactory'”异常，通常是由于找不到 mybatis-config.xml 文件导致的。该异常的完整信息可能包含以下内容：

解决方法:

1. 检查配置文件路径: 确保 mybatis-config.xml 文件位于正确的路径下。通常情况下，该文件应该放在 resources 目录下，或者在 application.properties 或 application.yml 中配置 mybatis.config-location 属性来指定文件路径。
2. 检查文件存在性: 确保 mybatis-config.xml 文件确实存在，并且没有被意外删除或改名。
3. 重新构建项目: 尝试清理项目缓存并重新构建项目。这可以解决一些由于项目构建问题导致的配置文件无法找到的问题。
4. 清理缓存: 清理 IDE 或构建工具的缓存，确保项目能够正确加载配置文件。

如果上述方法都无法解决问题，请检查项目依赖关系，确保 Mybatis 相关的依赖项已正确配置。
