Null value to an Int field

I have an entity class which has an int field , in the table the cloumn type is Number (10,0). In the table default value is "NULL". Using Spring data JPA when I try select query using jpa I am getting below errors.

java.lang.IllegalArgumentException: Can not set int field com.test.app.entity.TestProject.baseUserIdNumber to null value

I cannot change anything in the table as this is already created and used in the production. Anything I can do with Entity class or JPQL

@Entity
public class TestProject {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int projectId;
    private String description;
    private String name;
    private int seqNumber
    private LocalDate startDateTime;
    private LocalDate endDateTime;
    @Column(name = "baseUserIdNumber")
    private int myfield;
    private String projStatus;



constructors ()
getters()
Setters()


}

You can just define the field with a default value and define as int instead of Integer so that it doesn't accept NULL values.

@Column(name = "my_column")
private int myField = 0;
