Mybatis插入数据返回主键ID

<insert >
             select last_insert_id() as id
        </selectKey>
    </insert>
注意：(此处为mysql)这里的selectKey的resultType 必须和实体对象中的id类型一致，否则报错。

oracle的如下：

<selectKey resultType="java.lang.Long" keyProperty="ID" order="AFTER">
      SELECT IBOKEE_COMM_TAG_LIBRARY_SEQ.nextval AS Id FROM DUAL
</selectKey>

实体类
public class ProductSync implements Serializable {
         private Long id;
         ...
         ...

}

dao Mapper
public interface ProductSyncMapper {
   
    /**
     * @param product Object
     * 新增纪录
     */
    public void add(ProductSync product);
   
   
}
