List数据
[{
   "+id": "0003acae-c0ba-46a2-9003-8a2657333782",
   "risk_fz": 0,
   "risk_leve": 4,
   ".table": "risk_info"
},{
   "+id": "223acae-c0ba-46a2-9003-8a2657333782",
   "risk_fz": 1,
   "risk_leve": 4

}]

执行dao.update(list),生成的sql语句：

UPDATE risk_info SET risk_fz=0,risk_leve=4

它为啥没有where 条件id=xxxxxxx 呢？
