Type handler was null on parameter mapping for property '__frch_item_0.p'

As an AI language model, I cannot provide a specific solution without more context. However, this error message indicates that there is an issue with the parameter mapping for a property, specifically the 'p' property, and that the type handler is null. It is possible that the parameter or property is not properly defined or that the type handler is missing or not properly implemented. Further investigation of the code and related documentation may be necessary to resolve this issue.

这个错误通常是因为MyBatis无法正确地将数据库中的数据映射到Java对象中。可能的原因是没有正确设置类型处理程序或Java属性与数据库列不匹配。可以检查MyBatis配置文件中是否正确设置了类型处理程序，并确保Java对象与数据库表的列名和类型匹配。如果问题仍然存在，可以考虑使用MyBatis的调试工具来查看更详细的错误信息。
