這篇文章將為大家詳細講解有關iBATIS參數有哪些,小編覺得挺實用的,因此分享給大家做個參考,希望大家閱讀完這篇文章后可以有所收獲。
iBATIS參數的學習,首先我們看看都有哪些iBATIS參數:
◆iBATIS參數之:原型參數
﹤select id="select1" parameterClass="java.lang.String" resultClass="AppLog"﹥ select ID as id, TYPE as type, DESCR as descr from APP_LOG where ID = #id# ﹤/select﹥
sqlMapper.queryForObject("select0", id);
◆iBATIS參數之:Map類參數
﹤select id="select2" parameterClass="java.util.HashMap" resultClass="AppLog"﹥ select ID as id, TYPE as type, DESCR as descr from APP_LOG where ID = #id# ﹤/select﹥
map.put("id", id);
AppLog log = (AppLog) sqlMapper.queryForObject("select0", map);
◆iBATIS參數之:對象參數
﹤select id="select3" parameterClass="AppLog" resultClass="AppLog"﹥ select ID as id, TYPE as type, DESCR as descr from APP_LOG where ID = #id# ﹤/select﹥
AppLog p=new AppLog();
p.setId(id);
AppLog log = (AppLog) sqlMapper.queryForObject("select3", p);
﹤select id="select0" resultClass="AppLog"﹥ select ID as id, TYPE as type, DESCR as descr from APP_LOG where ID = #id# ﹤/select﹥
Map參數 map.put("id", id);
AppLog log = (AppLog) sqlMapper.queryForObject("select0", map);
String參數 AppLog log = (AppLog) sqlMapper.queryForObject("select0", id);
對象參數 AppLog p=new AppLog();
p.setId(id);
AppLog log = (AppLog) sqlMapper.queryForObject("select0", p);
