mybatis是没有通用dao层的,都要一个方法写一个sql语句例如:
//先写一个dao接口public interface CustomerDao{ Map getUserByAccounts(String accounts); Map getUserDetailById(int id); void lossAccountsByUserId(String userId); PageList> getCanReversedList(Map queMap); PageList> searchAccountsAnomaly(Map param); Map isHasAccounts(String accounts); void accountsRecover(Map updateInfo);}//在写一个dao的xml文件 select * from apdp_user a where UPPER(a.username)=UPPER(#{accounts}) select u.id,u.id_card,u.bind_phone from kc_user_detail u where u.id=#{id} select k.*,k2.app_time as CZ_TIME,k2.DISCOUNT_FEE as REVERSED_FEE from kc_phone_charge_app k left join (select * from kc_phone_charge_app a where a.type_id=2) k2 on k.reversed_app_id=k2.id left join apdp_user u on k.app_user_id=u.id where k.app_time > (SYSDATE -3) and k.TYPE_ID=1 and k.CHARGE_PHONE_NO like #{CHARGE_PHONE_NO}||'%' and k.SEQ_CODE like #{SEQ_CODE}||'%' and to_char(k.APP_TIME,'yyyy-MM-dd') >= #{rechargeDate1} ]]> and to_char(k.APP_TIME,'yyyy-MM-dd') <= #{rechargeDate2} ]]> and to_char(k2.APP_TIME,'yyyy-MM-dd') >= #{acceptDate1} ]]> and to_char(k2.APP_TIME,'yyyy-MM-dd') <= #{acceptDate2} ]]> and upper(u.USERNAME) like upper(#{userCode}||'%') and k.APP_USER_NAME like '%'||#{userName}||'%' order by k.app_time DESC select a.*,u.realname unlockUser from KC_ACCOUNT_ANOMALY a left join apdp_user u on a.unlock_user=u.id where upper(a.user_accounts)=upper(#{accounts}) order by a.anomaly_time DESC select * from apdp_user u where upper(u.username)=upper(#{accounts}) update apdp_user a set a.accountloss='1' where a.id=#{userId} update kc_account_anomaly a set a.unlock_time=SYSDATE,a.unlock_user=#{userId},a.status=0 where a.id=#{id}
建议你去百度文库直接搜mybatis的教程资料,有更加详细的解释和例子
