這個(gè)類是最原始的去DAO，封裝了一些數(shù)據(jù)的增刪查改，然后我編寫了數(shù)據(jù)訪問接口，數(shù)據(jù)訪問的實(shí)現(xiàn)類繼承自這個(gè)類再實(shí)現(xiàn)接口。代碼如下：
import com.custservice.base.BasdBase;
import com.custservice.basicdao.BaseDAO;
public class BasdService extends BaseDAO implements BasdBase {
public boolean delete(Object obj) {
return super.delObject(obj);
}
public boolean saveObj(Object obj) {
return super.addObject(obj);
}
}
當(dāng)我AOP的切入點(diǎn)配置到BaseDAO是事務(wù)是不會(huì)提交的，這個(gè)事務(wù)的切入點(diǎn)必須配置到直接訪問數(shù)據(jù)庫(kù)類的上一層。配置文件如下：

<tx:attributes>
<tx:method name="save*"
propagation="REQUIRED" />
<tx:method name="update*"
propagation="REQUIRED" />
<tx:method name="del*" propagation="REQUIRED" />
<tx:method name="*" read-only="true" />
</tx:attributes>
</tx:advice>
