Mybatis+mysql主键自增长,插入语句返回主键id

#（一）SQL语句获取主键自增长的id

<-/ 通过此语句获取主键id，我的id是Long类型keyProperty中写主键列的字段名称，执行之后要插入的类id就会自动赋值->

        
            SELECT LAST_INSERT_ID() AS id
        

        <-这里写插入语句，平时怎么写，这里怎么写就可以了->

        insert into shop_goods
        
            id,
            shop_id,
            category_id,

#（二）service层取出id返回

public Long addGoods(Goods goods) {
//调用Mapper执行第一步的插入语句
        goodsMapper.addGoods(goods);
        //通过类的get方法获取返回的id值
        Long id=goods.getId();
        return id;
    }
