Java 使从JSON模式生成的POJO类可序列化

我正在使用jsonschema2pojo maven插件v0.4.7从JSON模式生成POJO类。 示例模式如下所示：

 "features": {
            "title": "Feature",
            "description": "Name and type of every feature in the model",
            "type": "array",
            "items": {
                "properties": {
                    "columnName": {
                        "description": "Name of the table column",
                        "type": "string"
                    },
                    "featureName": {
                        "description": "Name of that column's feature for the pipeline",
                        "type": "string"
                    },
                    "type": {
                        "description": "Type of the feature",
                        "type": "string"
                    }
                },
                "required": ["columnName", "type"]
            }

public class Feature {

    /**
     * Name of the table column
     * 
     */
    @JsonProperty("columnName")
    private String columnName;
    /**
     * Name of that column's feature for the pipeline
     * 
     */
    @JsonProperty("featureName")
    private String featureName;
    /**
     * Type of the feature
     * 
     */
    @JsonProperty("type")
    private String type;
    @JsonIgnore
    private Map<String, Object> additionalProperties = new HashMap<String, Object>();

    /**
     * Name of the table column
     * 
     * @return
     *     The columnName
     */
    @JsonProperty("columnName")
    public String getColumnName() {
        return columnName;
    }

    /**
     * Name of the table column
     * 
     * @param columnName
     *     The columnName
     */
    @JsonProperty("columnName")
    public void setColumnName(String columnName) {
        this.columnName = columnName;
    }

    /**
     * Name of that column's feature for the pipeline
     * 
     * @return
     *     The featureName
     */
    @JsonProperty("featureName")
    public String getFeatureName() {
        return featureName;
    }

    /**
     * Name of that column's feature for the pipeline
     * 
     * @param featureName
     *     The featureName
     */
    @JsonProperty("featureName")
    public void setFeatureName(String featureName) {
        this.featureName = featureName;
    }

    /**
     * Type of the feature
     * 
     * @return
     *     The type
     */
    @JsonProperty("type")
    public String getType() {
        return type;
    }

    /**
     * Type of the feature
     * 
     * @param type
     *     The type
     */
    @JsonProperty("type")
    public void setType(String type) {
        this.type = type;
    }

    @Override
    public String toString() {
        return ToStringBuilder.reflectionToString(this);
    }

    @JsonAnyGetter
    public Map<String, Object> getAdditionalProperties() {
        return this.additionalProperties;
    }

    @JsonAnySetter
    public void setAdditionalProperty(String name, Object value) {
        this.additionalProperties.put(name, value);
    }

    @Override
    public int hashCode() {
        return new HashCodeBuilder().append(columnName).append(featureName).append(type).append(additionalProperties).toHashCode();
    }

    @Override
    public boolean equals(Object other) {
        if (other == this) {
            return true;
        }
        if ((other instanceof Feature) == false) {
            return false;
        }
        Feature rhs = ((Feature) other);
        return new EqualsBuilder().append(columnName, rhs.columnName).append(featureName, rhs.featureName).append(type, rhs.type).append(additionalProperties, rhs.additionalProperties).isEquals();
    }

}

生成的POJO类大致如下所示：

 "features": {
            "title": "Feature",
            "description": "Name and type of every feature in the model",
            "type": "array",
            "items": {
                "properties": {
                    "columnName": {
                        "description": "Name of the table column",
                        "type": "string"
                    },
                    "featureName": {
                        "description": "Name of that column's feature for the pipeline",
                        "type": "string"
                    },
                    "type": {
                        "description": "Type of the feature",
                        "type": "string"
                    }
                },
                "required": ["columnName", "type"]
            }

    }

     * @param columnName
     *     The columnName
     */
    @JsonProperty("columnName")
    public void setColumnName(String columnName) {
        this.columnName = columnName;
    }

    /**
     * Name of that column's feature for the pipeline
     * 
     * @return
     *     The featureName
     */
    @JsonProperty("featureName")
    public String getFeatureName() {
        return featureName;
    }

    /**

     * 
     * @param featureName
     *     The featureName
     */

    public void setFeatureName(String featureName) {
        this.featureName = featureName;
    }

    /**

    @JsonProperty("type")

        return type;
    }

    /**

     *     The type
     */
    @JsonProperty("type")
    public void setType(String type) {
        this.type = type;
    }

    @Override

        return ToStringBuilder.reflectionToString(this);
    }

    @JsonAnyGetter
    public Map<String, Object> getAdditionalProperties() {
        return this.additionalProperties;
    }

    @JsonAnySetter
    public void setAdditionalProperty(String name, Object value) {
        this.additionalProperties.put(name, value);
    }

    @Override
    public int hashCode() {

    }

    @Override

}

有人知道如何使POJO类实现可序列化吗？ 它们的JSON模式设置是否使其可序列化

我在谷歌上到处找都找不到运气。

提前感谢。

jsonschema2pojo团队表示已经实施：

“针对0.3.7进行了修复。现在有一个新的扩展属性“javaInterfaces”，它接受一个字符串数组，其中每个字符串都是Java接口的完全限定名。生成的类型将实现这些接口。”

您可能只是在寻找JSON.stringify？我不认为你有我的问题。我现在编辑了这个问题。谢谢。哈哈，我真的没有。我很抱歉。我的回答是，我仍然在看JavaScript问题，而不是Java问题。我的道歉。：）成功了。非常感谢你。不幸的是，我没有足够的声誉来支持这个答案。
