如何在改造中序列化空值響應？

Question

GsonConverter在數據可用的情況下進行解析，但是當發生空值時，它不解析數據。

這裏是JSON響應

{ 
    "data": [{ 
     "name": "abc store", 
     "services": [ 
      [ 
       "Travel Clinic", 
       "Growler Fill", 
       "Fresh Food" 
      ] 
     ] 
    }, { 
     "name": "abc store", 
     "services": [ 
      [ 
       "Travel Clinic", 
       "Coffee Bar", 
       "Growler Fill", 
       "Fresh Food", 
       "Scoop Ice Cream" 
      ] 
     ] 
    }, { 
     "name": "abc store", 
     "services": [ 
      "" 
     ] 
    }] 
} 

這裏是模型 Model.java

{ 
    private String name; 

    @SerializedName("services") 
    ArrayList<ArrayList<String>> storeServices; 

    } 

我已經使用了這些依賴關係：

com.squareup.retrofit2:converter-gson:2.1.0 
com.squareup.retrofit2:retrofit:2.1.0

我想這個問題是在你的改造模型。你能證明嗎？

或嘗試這一個

public class Example { 

@SerializedName("services") 
@Expose 
public List<List<String>> services = null; 

}
