org.apache.ibatis.exceptions.PersistenceException是MyBatis框架中的一个异常类。它是一个通用的持久化异常，当在执行数据库操作时发生错误时，MyBatis会抛出该异常。通常，它是由底层数据库操作引起的，比如SQL语法错误、连接问题、事务问题等。开发者可以通过捕获该异常来处理相关的持久化操作错误。

这个错误出现在使用 MyBatis 框架时，可能是因为配置文件中的数据源属性 maxPoolPreparedStatementPerConnectionSize 被认为是未知的。可以检查配置文件中的数据源属性是否正确，或者尝试将其删除并测试是否能够解决问题。如果问题仍然存在，可能需要检查 MyBatis 和数据库驱动程序的版本是否兼容。
