fastjson {"awardId":["JP66640947116481"],"activityId":"HD66670755317350"}

根据提供的引用内容，您可以使用fastjson库将一个JSON字符串解析为Java对象。下面是一个示例代码：

import com.alibaba.fastjson.JSON;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        String jsonStr = "{\"awardId\":[\"JP66640947116481\"],\"activityId\":\"HD66670755317350\"}";

        // 解析JSON字符串
        DrawRequest drawRequest = JSON.parseObject(jsonStr, DrawRequest.class);

        // 打印解析结果
        System.out.println("awardId: " + drawRequest.getAwardId());
        System.out.println("activityId: " + drawRequest.getActivityId());
    }
}

class DrawRequest {
    private List<String> awardId;
    private String activityId;

    public List<String> getAwardId() {
        return awardId;
    }

    public void setAwardId(List<String> awardId) {
        this.awardId = awardId;
    }

    public String getActivityId() {
        return activityId;
    }

    public void setActivityId(String activityId) {
        this.activityId = activityId;
    }
}

这段代码将会输出以下结果：

awardId: [JP66640947116481]
activityId: HD66670755317350
