Thank you all figured out the problem was in

@SequenceGenerator(name = "sequence", sequenceName = "seq_operator_id", allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequence")

in every object model!
Previously, this project was launched along with the Oracle database, and it supports SequenceGenerator, but now it launched with MySql and there was a conflict!
