Java Json字符串或Json对象属性查找工具类

给定参数Json字符串或者是Json对象，和需要查找的属性的key值，调用方法后可以获取到对应属性的值的FinalFastJsonObject对象，然后根据需要获取对象的值。

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import lombok.Data;
import org.apache.commons.lang3.StringUtils;

import java.io.Serializable;


@Data
public class FinalFastJsonObject implements Serializable {

    private static final long serialVersionUID = 1L;

    private Object object;

    private boolean isArray;

    public JSONArray getJSONArray() {
        return (JSONArray) object;
    }

    public JSONObject getJSONObject() {
        return (JSONObject) object;
    }

    public String getValue() {
        return (String) object;
    }

    public Object getObjectValue() {
        return object;
    }

    public boolean isNullOrBlankValue() {
        if (object == null) {
            return true;
        }
        if (object instanceof String) {
            return StringUtils.isBlank((String) object);
        }
        return false;
    }

}
