Question

我正在尝试使用datasaourceTransactionManager实现spring的事务管理。这是我的application-context.xml

    <context:component-scan base-package="com"/>
    <aop:aspectj-autoproxy />    

   <bean   id="dataSource"
    class="org.apache.commons.dbcp.BasicDataSource"
    p:driverClassName="oracle.jdbc.driver.OracleDriver"
    p:url="jdbc:oracle:thin:@//localhost:1521/XE"

   <bean id="datasourceTransactionManager"
         class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
         p:dataSource-ref="dataSource"   />

   <bean id="daoClass"
         class="com.dao.DaoClass"
         p:sessionFactory-ref="sessionFactory"
         p:dataSource-ref="dataSource"
         /> 

           <tx:advice id="transactionAdvice" transaction-manager="datasourceTransactionManager">
        <tx:attributes>
            <tx:method name="enterPublisher"/>
        </tx:attributes>
    </tx:advice>

    <aop:config>

        <aop:pointcut id="transactionPointcut" expression="execution(* com.dao.DaoClass.*(..))"/>
        <aop:advisor advice-ref="transactionAdvice" pointcut="transactionPointcut"/>

    </aop:config>

   <bean id="sessionFactory"
         class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
         p:dataSource-ref="dataSource"
         p:configLocation="/configs/hibernate.cfg.xml">
       <property name="hibernateProperties">
           <map>
               <entry key="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/>
               <entry key="hibernate.show_sql" value="true"/>
           </map>
       </property>
   </bean>

但是，在启动应用程序时，我收到以下异常。

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [configs/appContext.xml]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Pointcut is not well-formed: expecting '(' at character position 0

我似乎无法找到切入点表达式的问题。我哪里错了？

Answer 1

使用pointcut-ref代替pointcut中的aop:advisor属性。

Spring声明式事务建议切入点错误
