Spring Data JDBC: DataRetrievalFailureException : Unable to cast [oracle.sql.ROWID] to [java.lang.Number]

Question

I am new to Spring Data JDBC, and I am struggling to create a simple Dto and get it persisted on the DB.

I am using Spring-Boot 2.1.1.RELEASE and and Oracle 12 Database.

I think you need to declare the USR_ID field and corresponding sequence in your entity

@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "XXXX")
@SequenceGenerator(sequenceName = "YYYY", allocationSize = 1, name = "XXXX")
Long USR_ID;
