方式一:
调用它的分页方法:List result = sqlMapClient.queryForList(sqlid, parameterObject, begin, length);
方式二:
利用不同数据库的特点,把分页的条件作为参数传进去,在SQL语句处拼接。如MYSQL数据库可以使用它的limit函数。
比较:方式二比较通用,只需调用相同的方法,即可实现分页或者不分页,此时分页的参数只是做为普通的参数。
方式一比较简单,在SQL语句处无需关注分页的问题,ibatis会自动帮你分页(因为你调用了它的分页方法)。
示例代码:
方式一的代码:
Map parameterObject=
new
HashMap();
String sqlid=
"address.getAddressList"
;
int begin
=
0
;
int length
=
25
List result = sqlMapClient.queryForList(sqlid, parameterObject, begin, length);
<select id=
"getAddressList"
parameterClass=
"java.util.HashMap"
resultClass=
"last.soul.common.beans.Address"
>
select id, username, name, sex, mobile, email, qq, company, address, postcode
from address
</select>
方式二的代码:
Map parameterObject=
new
HashMap();
parameterObject.put(
"orderByClause"
,
"username asc"
);
parameterObject.put(
"limimitClauseStart"
, startIndex);
parameterObject.put(
"litClauseCount"
, pageSize);
String sql=
"address.getAddressList"
;
List result = sqlMapClient.queryForList(sql, parameterObject);
<select id=
"getAddressList"
parameterClass=
"java.util.HashMap"
resultClass=
"last.soul.common.beans.Address"
>
select id, username, name, sex, mobile, email, qq, company, address, postcode
from address
<isParameterPresent>
<isNotNull property=
"orderByClause"
>
order by $orderByClause$
</isNotNull>
<isNotNull property=
"limitClauseStart"
>
limit $limitClauseStart$, $limitClauseCount$
</isNotNull>
</isParameterPresent>
</select>
