地圖JSON嵌套對象從MongoDB中到Java

Question

我得到的JSON對象我的MongoDB與virustotal API 這是存儲在MongoDB中對象JSON對象的模樣：

{ 
"_id" : ObjectId("597cd2f871eac714388b2f7f"), 
"results" : { 
    "scans" : { 
     "Bkav" : { 
      "detected" : true,

     } 
    }, 
    "scan_id" : "2ad6e0aad0b40f152f234787daa4afb87538f3278f5c8f815d53ef46d5eea4ac-1467833095",

    "resource" : "0a60424e0967b6cfc172dac82e10a2fe", 
    "response_code" : 1, 
    "scan_date" : "2016-07-06 19:24:55", 
    "permalink" : "https://www.virustotal.com/file/2ad6e0aad0b40f152f234787daa4afb87538f3278f5c8f815d53ef46d5eea4ac/analysis/1467833095/",

    "md5" : "0a60424e0967b6cfc172dac82e10a2fe" 
}, 
"response_code" : 200 
} 

正如你所看到的JSON對象是太複雜，只得到給定值從， 這是我試過到目前爲止：

MongoClient mongo = new MongoClient("localhost", 27017); 
     MongoDatabase database1 = mongo.getDatabase(db); 
     MongoCollection<Document> collection1 = database1.getCollection(col); 
     try (MongoCursor<Document> cursor = collection1.find().iterator()){ 

      while (cursor.hasNext()){ 
       Document doc = cursor.next(); 
       List list = new ArrayList(doc.values()); 
       System.out.println(list.get(1)); 
      } 

     } 

我想也許有一種方法，所有這一切的JSON映射到Java類，主要問題與"scans"一樣有許多不同的掃描儀，它並沒有優化創建一個Java類模型到他們每個人，我的問題是我如何直接存儲我的JSON對象到一個Java對象，以便對返回的結果進行操作。

Answer 1

我打電話給您的主要模型掃描。您可以使用以下屬性創建一個POJO（讓我們稱之爲掃描儀）：
scannerName，檢測到的版本，結果，更新;

Scanner.java

private String scannerName; 
private String detected; 
private String version; 
private String result; 
private String update; 

Scan.java

private String scan_id; 
private List<Scanner> = new ArrayList<Scanner>(); 
private String sha1; 
private String resource; 
...... 
........ 

所以您的掃描模式目前擁有的掃描儀列表。

使用嗎啡它是這樣的：

@Embedded 
private List<Scanner> scanner; 

如果你不使用圍繞Java驅動程序的任何包裝，只要嘗試

private List<BasicDBObject> 

Answer 2

你需要爲了解析創建兩個Java類來自Mongo的Json，假設頭等名稱"CollectionReceived" 二級名稱"Result" 在CollectionReceived類中您需要聲明成員

public String _id; 
public String response_code; 
public Result result; 

在結果類，你需要聲明會員

Map<String,Map<String,Map<String,Map<String,Object>>>> results=new HashMap<String,Map<String,Map<String,Map<String,Object>>>>();, 
public String scan_id; 
public String sha1; 
public String resource; 
public String response_code; 
public String scan_date; 
public String permalink; 
public String verbose_msg; 
public String total; 
public String positives; 
public String sha256; 
public String md5; 

，不要忘記你的控制器上使用@RestController，你會很容易解析JSON，並得到所有你需要的值。
