Jackson json解析器异常

Question

com.fasterxml.jackson.databind.jsonMappingException：属性“wallpaper”的setter定义冲突：在RializerCache._CreateAndCache2(deserializerCache.java:298)...com.fasterxml.jackson.databind.objectMapper._ReadMapandClose(ObjectMapper.java:2884)在com.fasterxml.jackson.databind.objectMapper.ReadValue(ObjectMapper.java:2034)

我的课看起来是这样的

@JsonIgnoreProperties(ignoreUnknown = true)
@JsonInclude(Include.NON_NULL)
public class SubscriptionWrapper {

    @JsonProperty("device")
    private Device device;

    @JsonProperty("subscriptions")
    private List<Subscription> subscriptions;

    public SubscriptionWrapper() {
    }

    public SubscriptionWrapper(Device device, List<Subscription> subscriptions) {
        this.device = device;
        this.subscriptions = subscriptions;
    }

    public Device getDevice() {
        return device;
    }

    public void setDevice(Device device) {
        this.device = device;
    }

    public List<Subscription> getSubscriptions() {
        return subscriptions;
    }

    public void setSubscriptions(List<Subscription> subscriptions) {
        this.subscriptions = subscriptions;
    }

}

知道会出什么问题吗？我在其他项目中使用过jackson没有任何问题。

该死，我找到了解决办法：

我的设备类有一个方法

public void setStatistics(Context c);

它将被调用以实现有关用户设备的统计信息。

@JsonIgnore
public void setStatistics(Context c)
