使用杰克逊解析领域模型 [英] Parse realm model using jackson

问题描述

使用杰克逊库将领域模型转换为json对象时获取未知密钥.

Getting unknown key while converting realm model into json object using jackson library.

这是我的领域模型实例.

Here is my realm model instance.

    public class RecordData extends RealmObject {

    public RecordData() {

    }

    private FormData formData;

    @Nullable
    @JsonProperty("values")
    private RealmList<Values> values;

    @Nullable
    @JsonProperty("value")
    private String value;
}

用于将领域模型转换为json对象的代码.

Code for converting realm model to json object.

JSONObject recordDataJsonObject = new JSONObject(new ObjectMapper().writeValueAsString(formData.getRecordData()));

解析json的输出:

{"loaded":true,"managed":false,"valid":true,"value":"fdfdf","values":[]}

领域版本:io.realm:realm-gradle-plugin:4.1.1

Rxjava版本:'io.reactivex.rxjava2:rxjava:2.1.6'

Rxjava version : 'io.reactivex.rxjava2:rxjava:2.1.6'

Jackson版本:com.fasterxml.jackson.core:jackson-databind:2.8.6

Jackson version : com.fasterxml.jackson.core:jackson-databind:2.8.6

为什么我要加载，管理和有效的布尔值?

Why i am getting loaded, managed and valid boolean values ?

推荐答案

您可以使用@JsonIgnoreProperties批注:

@JsonIgnoreProperties({"loaded", "managed", "valid"})
public class RecordData extends RealmObject {

    public RecordData() {

    }

    private FormData formData;

    @Nullable
    @JsonProperty("values")
    private RealmList<Values> values;

    @Nullable
    @JsonProperty("value")
    private String value;
}

另一种选择是使用@RealmClass public class RecordData implements RealmModel.
