how to save entities with data manager without set id because auto increment

When creating an entity in Studio, use long/int identifier with value of “Identity column”:

It’s highly recommended also to add UUID trait to such entities.

So the source code will look as follows:

@JmixEntity
@Table(name = "FOO")
@Entity
public class Foo {
    @Column(name = "ID", nullable = false)
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @JmixGeneratedValue
    @Column(name = "UUID")
    private UUID uuid;

    @Column(name = "NAME")
    private String name;

// getters and setters

New instances of such entities can be saved via DataManager with null ids.
