mysql插入返回当前生成的主键

1：sql中需要添加属性 keyColumn="base_price_id" keyProperty="basePriceId" useGeneratedKeys="true"<insert id="insertBasePrice" parameterType="com.olymtech.bs.freight.trk.vo.BasePriceResultVO"

keyColumn="base_price_id" keyProperty="basePriceId" useGeneratedKeys="true">

insert into truck_base_price (product_id, casenumber, base_price20, base_price40,remark) values (#{productId,jdbcType=BIGINT}, #{casenumber,jdbcType=INTEGER}, #{basePrice20,jdbcType=DECIMAL}, #{basePrice40,jdbcType=DECIMAL},#{remark,jdbcType=VARCHAR}) </insert>2：返回到对应的实体中，如果要取到，则：

public Boolean addBasePrice(BasePriceResultVO basePriceResultVO)throws DataAccessException{ Boolean resultFlag=false; try { //先查询产品表该产品是否存在 Long productId = null; TruckProduct trkProduct = truckProductDao.selectProductByIds(basePriceResultVO); if(trkProduct == null){ truckProductDao.insertBaseProduct(basePriceResultVO); productId = basePriceResultVO.getProductId(); }else{ productId = trkProduct.getProductId(); } basePriceResultVO.setProductId(productId); //TODO需要调车队相关的接口（暂时写死） basePriceResultVO.setCasenumber(1); truckBasePriceDao.insertBasePrice(basePriceResultVO); Long basePriceId = basePriceResultVO.getBasePriceId(); if(basePriceId != null){ basePriceResultVO.setBasePriceId(basePriceId); basePriceResultVO.setOperationType(TruckUtil.ADD); Long resultId=truckBasePriceHistoryDao.insertTruckBasePriceHistory(basePriceResultVO); if(resultId!=null){ resultFlag = true; } } } catch (Exception ex) { LOGGER.error("TruckBasePriceServiceImpl.addBasePrice异常" + ex); } return resultFlag; }
