Cause:
Mapping not found
Solution:
1. The original idea is stuck: whether to match and inherit the correct relationship between the product and book. Check, compare, and confirm that there are no errors in the inheritance relationship configuration several times, but it is still difficult to find the Book is not mapped.
2. I don't want to go back and look for the Hibernate project. Is there anything missing? I finally found that I forgot to add <value> badyflf/action/mapping/Product. hbm. xml </value> to ssh. xml.
