ibtais中user.xml中的.page.end与page.start怎么赋值的?

user.xml
只有这两个page对象调用

<![CDATA[
select * from (select rownum rn,tu.party_id,tu.user_account,tu.password,tu.valid,tu.creater_id,tu.create_time,
tu.password_status,tu.terminal_use_flag,tu.desktop_use_flag,tu.valid_desk,tu.flag,tu.work_code,tu.team_code,tu.transfer_type,tu.card_transfer_type,
tp.party_name,tor.org_name,tor.org_code,tor.manager_org_code
]]>

<![CDATA[
and rownum<=# page.end #
) A WHERE rn> ** #page.start# **

]]>
