改装响应映射错误[重复]

Question

这是我的服务器响应；

{
"data": {
    "constants": [
        {
            "SIZECCbendRatio": "0.99"
        },
        {
            "SIZECCminRatio": "1.45"
        },
        {
            "SIZECCmaxRatio": "1.75"
        }
    ],
    "agent": "NO",
    "status": "Success",
    "message": "Did not find any agent information on User  agent status was found"
    }
}

我的服务器响应在这里，它返回一些参数和一些常量的Json数组格式的值…

public class GetAgentInfo {
@SerializedName("data")
public Data data;

public static class Data {
    @SerializedName("constants")
    public Constant constants;
    @SerializedName("agent")
    public String agent;
    @SerializedName("status")
    public String status;
    @SerializedName("message")
    public String message;
}
public static class Constant{
    public Map<String,Object> values = new HashMap<String, Object>();
}
}

java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 23 path $.data.constants..

Answer 1

常数是一个数组

public List<Constant> constants;
