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;

}
