----其它涉及的类-----

Provice.class

1 import java.util.List; 2  3 public class Province { 4     private String name; 5     private List<City> citys; 6     public Province() { 7         super(); 8         // TODO Auto-generated constructor stub 9     }10     public Province(String name, List<City> citys) {11         super();12         this.name = name;13         this.citys = citys;14     }15     public String getName() {16         return name;17     }18     public void setName(String name) {19         this.name = name;20     }21     public List<City> getCitys() {22         return citys;23     }24     public void setCitys(List<City> citys) {25         this.citys = citys;26     }27     28     29 }

City.class
