List to JSON：Play Framework：Java

Question

我正在使用Java的play framework。我們可以如何將List轉換爲Json？

我試圖與下面的代碼：

List<XYZ> data = PQRDao.func01(); 

return ok(Json.toJson(data)); 

輸出：

[["1","APPLE"],["2","BANANA"],["3',"ORANGE"]] 

實際需求：提前

[{"code": "1","fruitName": "APPLE"},{"code": "2","fruitName": "BANANA"},{"code": "3',"fruitName": "ORANGE"}] 

感謝

Answer 1

這是一個簡單的for循環您東東d.below是工作碼

<script> 
 
    
 
    var list = [["1","APPLE"],["2","BANANA"],["3","ORANGE"]]; 
 
    var finalList =[]; 
 

 
    function createJson() { 
 
for(var i=0;i<list.length;i++){ 
 
    var item = list[i]; 
 
    var obj = {}; 
 
    obj.code = item[0]; 
 
    obj.fruitName =item[1]; 
 
    finalList.push(obj); 
 
} 
 
    console.log(finalList); 
 
    } 
 
    </script> 
 
<button onclick="createJson()"> Format</button>
