jfinal的Db.save()报错问题?报错

执行如下代码的时候

Record instrData = new Record();
instrData.set("xiangmu", params[0]).set("pri_by", params[1]).set("pri_by_lj", params[2]);
instrData.set("pri_qntq", params[3]).set("pri_qntq_lj", params[4]);
instrData.set("pri_qntq_zzl", params[5]).set("pri_qntq_lj_zzl", params[6]);
instrData.set("nian",nian).set("yue", yue);

Db.save("TBL_DATA_SYTBDATA", "GUID", instrData);

在Db.save()时，控制台报错：

com.jfinal.plugin.activerecord.ActiveRecordException: java.sql.SQLException: An SQLException was provoked by the following failure: java.lang.ArrayIndexOutOfBoundsException: 9

求告知，什么原因导致？谢谢
