自定義對象轉換成json字符串時,空值不顯示的問題解決

String recInspectApplicationJsonString = JSON.toJSONString(recInspectApplicationPO, SerializerFeature.WriteNullStringAsEmpty, SerializerFeature.WriteNullBooleanAsFalse);
   

 JSON.toJSONString(自定義對象, SerializerFeature.WriteNullStringAsEmpty, SerializerFeature.WriteNullBooleanAsFalse);

 

json機制內,默認將空值不轉換爲json內的對象;
