在Jackson中,可以通过以下方式定义父对象和子对象之间的链接 @JsonManagedReference和@JsonBackReference,如
public class User {
public int id;
public String name;
@JsonBackReference
public List<Item> userItems;
}
public class Item {
public int id;
public String itemName;
@JsonManagedReference
public User owner;
}
如果孩子们存储在地图中,可以使用相同的链接,例如:
public class User {
public int id;
public String name;
@JsonBackReference
public Map<String, Item> userItems;
}
public class Item {
public int id;
public String itemName;
@JsonManagedReference
public User owner;
}
