jOOQ-dao-插入对象的主键

Question

I am using the DAO's as generated by jOOQ:

<generate>
    <relations>true</relations>
    <records>true</records>
    <pojos>true</pojos>
    <daos>true</daos>
    <interfaces>true</interfaces>
    <globalObjectReferences>true</globalObjectReferences>
    <jpaAnnotations>true</jpaAnnotations>
    <validationAnnotations>true</validationAnnotations>
    <fluentSetters>true</fluentSetters>
</generate>

After inserting a POJO to the database, how do I get the created identifier/primary key? The insertion succeeds, but calling getIdentifier() on the POJO still returns null .

Answer 1

This is a missing feature in jOOQ 3.5 and is tracked as two independent feature requests:

• #2536 - In DaoImpl set the Id of the inserted pojo
• #3021 - Add DAO.insertAndFetch() to return the updated POJO from the database

Right now, you cannot fetch generated keys on insert unless you implement your own insert() method, or extend the code generator to generate that method for you.
