public class ProjectComponent extends AbstractEntity {

    @Id
    @Column(name = "id", nullable = false, length = 128)
    private String id;

    @Column(name = "project_name", nullable = false)
    private String projectName;

    @Column(name = "name", nullable = false, columnDefinition = "nvarchar")
    @Size(max = 512, message
            = "Cannot exceed 512 characters")
    private String name;
}

```

@Size(max=512) I used this in the entity field but whenever I crossed size 512 then this thing should stop on that particular field should not persist into DB and that means should not throw an exception from DB.
