如何在改造中序列化空值响应？

Question

GsonConverter在数据可用的情况下解析，但是当出现空值时，它不会解析数据。

这是json回复

 {
    "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": [
            ""
        ]
    }]
}

这是模型 Model.java

  { 
    private String name;

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

  }

我使用过这些依赖项：

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

我认为问题出在你的改造模型中。你能表现出来吗？

或试试这个

public class Example {

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

}
