Repeated column in mapping for entity: com.main.ToursTravels.model.VechileType column: name (should be mapped with insert="false" update="false")

Answer 1

You are mapping 3 different properties to the same column name:
#Column(name="name")
private boolean mini;
#Column(name="name")
private boolean sedan;
#Column(name="name")
private boolean suv;
Use different names instead:
#Column(name="mini")
private boolean mini;
#Column(name="sedan")
private boolean sedan;
#Column(name="suv")
private boolean suv;
A better, more extensible alternative could be to use an enum:
public enum VehicleKind {
MINI, SEDAN, SUV
}
And in VechileType
#Entity
#Table(name="vechiletype")
#Data
public class VechileType {
#Enumerated(EnumType.STRING)
private VehicleKind kind;
