圖書信息庫完整解決方案（六）豆瓣接口

爲了綜合噹噹和豆瓣的圖書詳情數據，這裏在圖書信息從噹噹抓取成功後，根據isbn信息再從豆瓣獲取一次圖書詳情數據。

相關豆瓣圖書的接口地址爲：

https://developers.douban.com/wiki/?title=book_v2#get_isbn_book

而後將豆瓣與噹噹的圖書詳情進行比對，豆瓣若是存在對應的字段則以豆瓣的爲準：

 1 private boolean compareBookInfo(BookInfo srcInfo, BookInfo dstInfo){
 2         boolean update = false;
 3         
 4         //title
 5         if(!StringUtils.isEmpty(srcInfo.getTitle()) 
 6                 && !srcInfo.getTitle().equalsIgnoreCase(dstInfo.getTitle())){
 7             dstInfo.setTitle(srcInfo.getTitle());
 8             update = true;
 9         }
10         
11         //subtitle
12         if(!StringUtils.isEmpty(srcInfo.getSubtitle())
13             && !srcInfo.getSubtitle().equalsIgnoreCase(dstInfo.getSubtitle())){
14             dstInfo.setSubtitle(srcInfo.getSubtitle());
15             update = true;
16         }
17

31             update = true;
32         }
33         
34         //author_info

38             update = true;

47         
48         //price
49         if(!StringUtils.isEmpty(srcInfo.getPrice())
50                 && StringUtils.isEmpty(dstInfo.getPrice())){

57                 && !srcInfo.getTags().equalsIgnoreCase(dstInfo.getTags())){

59             update = true;

61         
62         //summary
63         if(!StringUtils.isEmpty(srcInfo.getSummary())
64                 && !srcInfo.getSummary().equalsIgnoreCase(dstInfo.getSummary())){
65             dstInfo.setSummary(srcInfo.getSummary());
66             update = true;
67         }
68         
69         //catalog
70         if(!StringUtils.isEmpty(srcInfo.getCatalog())
71                 && !srcInfo.getCatalog().equalsIgnoreCase(dstInfo.getCatalog())){
72             dstInfo.setCatalog(srcInfo.getCatalog());
73             update = true;
74         }
75         
76         return update;
77     }

能夠在這個基礎上繼續完善對豆瓣和噹噹的數據合併處理。
