Spring boot variable re-naming issue (Hibernate)

Question

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:

  {
        "id": 1,
        "remarks": "demo3",
        "demanderRentLeadStatus": null,
        "demanderBuyLeadStatus": null,
        "supplierSellLeadStatus": null,
        "supplierRentLeadStatus": null,
        "sales": null,
        "lastname": "foo",
        "firstname": "bar",
        "assignTo": "david",
        "assignBy": "james",
        "requirements": "for rent out"
    }

Actual output for postman:

{
    "id": 1,
    "remarks": "demo3",
    "demanderRentLeadStatus": null,
    "demanderBuyLeadStatus": null,
    "supplierSellLeadStatus": null,
    "supplierRentLeadStatus": null,
    "sales": null,
    "lastName": null,
    "firstName": null,
    "assignmentTo": null,
    "assignmentBy": null,
    "requirments": null
}

Answer 1

Rename getter and setter of your class. Make it like: getter and setter for assignTo are getAssignTo() and setAssignTo(String s) respectively. and do same for assignBy.
