Question

我正在使用泽西和杰克逊创建一个网络应用程序。我已经做出了以下类型的回复POJO：

@JsonInclude(Include.NON_NULL)
public class ResponsePojo {

    private Integer id;
    private String name;
    private String imageUrl;
    private JsonObject queryParams;

    public ResponsePojo(Integer id, String name, String imageUrl, JsonObject queryParams) {
        this.id = id;
        this.name = name;
        this.imageUrl = imageUrl;
        this.queryParams = queryParams;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getImageUrl() {
        return imageUrl;
    }

    public void setImageUrl(String imageUrl) {
        this.imageUrl = imageUrl;
    }

    public JsonObject getQueryParams() {
        return queryParams;
    }

    public void setQueryParams(JsonObject queryParams) {
        this.queryParams = queryParams;
    }
}

当我省略private JsonObject queryParams;字段时，我从webAPI收到了正确的JSON响应。如何从响应POJO中返回JSON？

我收到以下错误：

Direct self-reference leading to cycle (through reference chain: my.package.Response["list"]->java.util.ArrayList[0]->my.package.ResponsePojo["queryParams"]->com.google.gson.JsonObject["asJsonObject"])

泽西和杰克逊：反应POJO包含JsonObject
