JHipster-JDL created entity/table PK autoincrement NO; how to change to YES

[djsg]

I used jhipster 8.7.1 to created a Spring Boot app. My database is PostgreSQL.

I found that autoincrement of primary key of jdl-created entity tables is NO.

• I wonder how does the Spring framework handle the primary key when doing table insertion.

I did a insertion test, the table ID had a big jump from 10 to 1000+, which seems not very good.

• Is there a way to make primary key autoincrement YES for jdl-created table?

What you are seeing is expected behavior in JHipster + PostgreSQL.

JHipster does not usually use the old PostgreSQL SERIAL auto-increment style.
Instead, it uses database sequences together with JPA/Hibernate.

So even if pgAdmin shows:

Autoincrement = NO
