Spring boot variable re-naming issue (Hibernate)

My variable names in entity class are assignTo and assignBy, The column name of the above in MySQL db are assignto and assignby respectively.

But project is creating it by name "assignmentTo" and "assignmentBy".

I have drop the whole databases and re-created with mvn clean install after deleting .m2/repository folder.

Postman is still returning "assignmentTo" and "assignmentBy" on GET API.

Called POST method with "assignTo" and "assignBy" names, still got "assignmentTo" and "assignmentBy".

Class LeadAssignment:

@Entity
@Table(name = "lead_assignment")
public class LeadAssignment {

        @Id
        @GeneratedValue(strategy = javax.persistence.GenerationType.IDENTITY )
        @Column(name = "laid", nullable = false, updatable = false)
        private Long id;

        @Column(name = "first_name", nullable = false)
        private String firstname;

        @Column(name = "last_name", nullable = false)
        private String lastname;

        @Column(name = "assignto" , nullable = false)
        private String assignTo;

        @Column(name = "assignby", nullable = false)
        private String assignBy;

        @Column(name = "requirement" , nullable = false)
        private String requirements;

        @Column(name = "remark" , nullable = false)
        private String remarks;

Expected postman output:

    }

Actual output for postman:
