import java.util.List;

import org.hibernate.Query;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

/*

 * 最基本的DAO操作,已供應(yīng)其他類來(lái)調(diào)用

 */

public class BaseDAO extends HibernateDaoSupport {

    /*

     * 添加

     */

    public boolean addObject(Object obj) {

       boolean state = true;

       try {

           this.getHibernateTemplate().save(obj);

       } catch (Exception e) {

           e.printStackTrace();

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(xiě)了數(shù)據(jù)訪問(wèn)接口，數(shù)據(jù)訪問(wèn)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(wèn)數(shù)據(jù)庫(kù)類的上一層。配置文件如下：

<tx:advice id="txAdvice" transaction-manager="transactionManager">

       <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>

    <aop:config>

       <aop:pointcut id="allMethod"

           expression="execution(* com.custservice.service.*.*(..))" />

       <aop:advisor pointcut-ref="allMethod" advice-ref="txAdvice" />
