Question

我无法使用Retrofit2 + Gson正确解析我的Web服务的响应。我已经实现了类似的响应，所有这些响应都正常。响应主体返回自定义对象数组时会发生此问题。

我已经阅读了很多来自stackoverflow的回复，并且我使用http://www.jsonschema2pojo.org/创建了我的课程但是没办法...

我粘贴了所有代码。希望您能够帮助我。谢谢！

改造响应类

public class RankingResponse {

@SerializedName("code")
@Expose
private String code;
@SerializedName("errorMessage")
@Expose
private Object errorMessage;
@SerializedName("data")
@Expose
private List<Datum> data = null;

public String getCode() {
    return code;
}

public void setCode(String code) {
    this.code = code;
}

public Object getErrorMessage() {
    return errorMessage;
}

public void setErrorMessage(Object errorMessage) {
    this.errorMessage = errorMessage;
}

public List<Datum> getData() {
    return data;
}

public void setData(List<Datum> data) {
    this.data = data;
}

@Override
public String toString() {
    return "RankingResponse{" +
            "code='" + code + '\'' +
            ", errorMessage=" + errorMessage +
            ", data=" + data +
            '}';
}


public class Datum {
    @SerializedName("nickname")
    @Expose
    private String nickname;
    @SerializedName("tiempoMiliseg")
    @Expose
    private Integer tiempoMiliseg;
    @SerializedName("fecha")
    @Expose
    private String fecha;

    public String getNickname() {
        return nickname;
    }

    public void setNickname(String nickname) {
        this.nickname = nickname;
    }

    public Integer getTiempoMiliseg() {
        return tiempoMiliseg;
    }

    public void setTiempoMiliseg(Integer tiempoMiliseg) {
        this.tiempoMiliseg = tiempoMiliseg;
    }

    public String getFecha() {
        return fecha;
    }

    public void setFecha(String fecha) {
        this.fecha = fecha;
    }

    @Override
    public String toString() {
        return "Datum{" +
                "nickname='" + nickname + '\'' +
                ", tiempoMiliseg=" + tiempoMiliseg +
                ", fecha='" + fecha + '\'' +

改造客户

public class RetrofitClient {

    private static Retrofit retrofit = null;

    public static Retrofit getClient(String baseUrl) {
        if (retrofit==null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }
}

改进回复

Answer 1

在您的RankingResponse类中替换以下内容：

@SerializedName("data")
@Expose
private List<Datum> data = null;

使用：

@SerializedName("data")
private List<Datum> data =  new ArrayList<Datum>();
