Spring Data JDBC

CosIdBeforeConvertCallback (artifact cosid-spring-data-jdbc, package me.ahoo.cosid.spring.data.jdbc) fills, before an aggregate is converted for saving, its @CosId field, and then an unset @Id from a generator (default unless configured).

java

public class Order {
    @Id
    private Long id;          // filled from cosid.jdbc.id-generator when unset
}

It is off by default, as in 4.x:

Property	Default
`cosid.jdbc.enabled`	`false`
`cosid.jdbc.id-generator`	`default`
