mybatis带有序列的插入sql--保留一个做纪念

<insert id="commit" parameterType="com.picc.hmims.productInfo.dto.ExamineBo">
        <selectKey keyProperty="taskId" resultType="String"    order="BEFORE">
            --             select seq_product_service_price.nextval from dual
            select nextval(‘seq_t_service‘)
        </selectKey>
        insert into T_EXAMINE_TASK
        (TASK_ID,TASK_CODE,BUSI_CODE,BUSI_NAME,BUSI_TYPE,TASK_TYPE,TASK_STATUS,TASK_RESULT,TASK_RESULT_DESC,ORG_CODE,APPLY_PERSON,APPLY_TIME,PREPARE,INSERT_OPER,INSERT_TIME
        )
        values(
        cast(#{taskId} as NUMERIC ),
        --seq_t_service.nextval,
