spring batch中MyBatisPagingItemReader分頁使用介紹

假如是mysql的話，SQL語句

<![CDATA[
select * from 
(
SELECT so.* FROM t_tm_sales_order so 
where so.last_modified_time >= to_timestamp('2015-05-05','yyyy-mm-dd hh24:mi:ss') 
order by so.id limit #{_pagesize} OFFSET #{_skiprows}  
) temp_a inner join t_tm_sales_order_line sol on temp_a.id=sol.so_id
]]>

假如是oracle的話，SQL語句

<![CDATA[
select t2.* from
(select t1.*,rownum rn from
(select * from a) t1 where rownum<= (#{_pagesize} + #{_skiprows})) t2 where t2.rn > #{_skiprows}
]]>

 xml配置：

<bean id="itemReader" class="org.mybatis.spring.batch.MyBatisPagingItemReader" scope="step">
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
    <property name="pageSize" value="1000"/>
    <property name="queryId" value="com.jr.gyl.base.pay.app.dao.erp.OpenLinkDao.queryByMutliParams" />
    <property name="parameterValues">
        <map>
            <entry key="companyName" value="#{jobParameters['companyName']}">
            </entry>
            <entry key="companyNo" value="#{jobParameters['companyNo']}">
            </entry>
            <entry key="startTime" value="#{jobParameters['startTime']}">
            </entry>
            <entry key="openBank" value="#{jobParameters['openBank']}">
            </entry>
            <entry key="endTime" value="#{jobParameters['endTime']}">
            </entry>
            <entry key="pageSize" value="#{jobParameters['pageSize']}">
            </entry>
        </map>
    </property>
</bean>
