JSON到Java映射帮助 - 嵌套集合

Question

我想找出一种方法来将此JSON字符串转换为Java对象图，但我无法这样做。下面，我插入了我的JSON字符串和我的两个类。我已经验证了它是一个有效的json结构。我一直在尝试谷歌API（http://sites.google.com/site/gson/gson-user-guide），但它没有映射嵌套的照片集。任何想法或替代图书馆？

{"photos":{"page":1,"pages":73514,"perpage":50,"total":"3675674","photo":[{"id":"5516612975","owner":"23723942@N07","secret":"b8fb1fda57","server":"5213","farm":6,"title":"P3100006.JPG","ispublic":1,"isfriend":0,"isfamily":0},{"id":"5516449299","owner":"81031835@N00","secret":"67b56722da","server":"5171","farm":6,"title":"Kaiser Boys Volleyball","ispublic":1,"isfriend":0,"isfamily":0}]},"stat":"ok"} 

Photos.java

public class Photos { 
private int pages; 
private int perpage; 
private String total; 
private List<Photo> photo; 
private String stat; 
public int getPages() { 
    return pages; 
} 
public void setPages(int pages) { 
    this.pages = pages; 
} 
public int getPerpage() { 
    return perpage; 
} 
public void setPerpage(int perpage) { 
    this.perpage = perpage; 
} 
public String getTotal() { 
    return total; 
} 
public void setTotal(String total) { 
    this.total = total; 
} 
public List<Photo> getPhoto() { 
    return photo; 
} 
public void setPhoto(List<Photo> photo) { 
    this.photo = photo; 
} 
public String getStat() { 
    return stat; 
} 
public void setStat(String stat) { 
    this.stat = stat; 
} 

}

Photo.java：

public class Photo { 
private String id; 
private String owner; 
private String secret; 
private String server; 
private String farm; 
private String title; 
private int isPublic; 
private int isFriend; 
private int isFamily; 
public String getId() { 
    return id; 
} 
public void setId(String id) { 
    this.id = id; 
} 
public String getOwner() { 
    return owner; 
} 
public void setOwner(String owner) { 
    this.owner = owner; 
} 
public String getSecret() { 
    return secret; 
} 
public void setSecret(String secret) { 
    this.secret = secret; 
} 
public String getServer() { 
    return server; 
} 
public void setServer(String server) { 
    this.server = server; 
} 
public String getFarm() { 
    return farm; 
} 
public void setFarm(String farm) { 
    this.farm = farm; 
} 
public String getTitle() { 
    return title; 
} 
public void setTitle(String title) { 
    this.title = title; 
} 
public int getIsPublic() { 
    return isPublic; 
} 
public void setIsPublic(int isPublic) { 
    this.isPublic = isPublic; 
} 
public int getIsFriend() { 
    return isFriend; 
} 
public void setIsFriend(int isFriend) { 
    this.isFriend = isFriend; 
} 
public int getIsFamily() { 
    return isFamily; 
} 
public void setIsFamily(int isFamily) { 
    this.isFamily = isFamily; 
} 

}

使用Jackson。它将负责转换到JSON和从JSON转换。它提供了多种处理转换的方法，并与Spring等框架良好集成。绝对是一个知道的人。
