Gson.toJson - 如何設計類與數組類

Question

我收到來自JSON格式的Elasticsearch的迴應，我希望Gson轉換成Java類，但是我有困難包裝我的頭如何開發這個課程。這是返回的JSON：

{ 
"took":3, 
"_shards":{ 
    "total":3, 
    "successful":3, 
    "failed":0 
}, 
"total":1, 
"matches":[ 
    { 
     "_index":"object_percolator", 
     "_id":"2" 
    }, 
    { 
     "_index":"object_percolator", 
     "_id":"3" 
    } 
] 
} 

'匹配'是什麼給我一個很難。我將如何設計類來處理該數組？有任何想法嗎？提前致謝！

Answer 1

class Matches{ 
    List<MatchesCollection> matchCollection=new ArrayList<MatchesCollection>(); 
//add getter and setter here 
} 
     class MatchesCollection { 
      private String _index; 
      private Integer _id; 
      //add getter and setter here 
     } 

//添加你需要檢索

嘗試google一下POJO
