Why doesn't Intellij IDEA allow us to create mappings based on our POJOs?

Hello! I want to create a mapping of my class (POJO), but idea only gives me the choice of Database schema, although there should also be an entity bean. (Ps eclipse has hibernate tools, which easily allows you to create mapping xml files, why is there no such thing in the idea?) How to fix this? I will be glad to see your advice and comments. Thank you.
