Answer 1

This is how I populate the drop down list.I think it may help to you get some idea about it.

Controller

List operators =  operatorService.getAllOperaors()
model.addAttribute("operators", operators);

Model

  @Entity
  @Table(name = "operator")
  public class Operator {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    @JsonIgnore
    private Long id;

    @NotBlank(message="operator Name cannot be empty")
    @Column(name = "operator_name", nullable = false)
    private String operatorName;

    getters and setters ...

}   

View

    
    select operator
