Caused by: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: java.lang.ClassNotFoundException: Cannot find class: mapper/EmployeeMapper.xml

这个错误是由于 MyBatis 在解析 SQL Mapper 配置文件时出现了问题，原因是找不到 EmployeeMapper.xml 文件所在的包。可能是因为文件路径或包名有误，或者是文件不存在。建议检查一下文件路径和包名是否正确，并确认文件是否存在。

这是一个关于Spring框架下bean创建时出现异常的错误，具体原因是在初始化CourseBaseMapper时，解析Mapper XML时出现了错误。错误的具体原因是在解析CourseBaseMapper.xml文件时，解析器无法找到类'com.xuecheng.content.model.dto.TeachplanDto'，导致初始化失败。

根据你提供的信息，这似乎是一个MyBatis插件的错误，插件试图调用一个名为"close"的方法，但在org.apache.ibatis.executor.Executor接口中找不到该方法。这可能是因为MyBatis版本与插件不兼容，或者插件中的代码有问题。建议检查插件代码和MyBatis版本，看是否需要升级或修改插件代码。
