Declare your column id as Integer and dont pass it from UI or pass value as null object. If you want to keep it int then always pass 0 from UI. Passing empty String will always raise exception until you dont have your own messageConverter handling.

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name=id)
private Integer id;
