springAOP注解方式定义切入点报错error at ::0 can't find referenced pointcut
【说明】
1、使用spring版本:4.0.4
2、springAOP相关依赖包：
1）aopalliance-1.0.jar
2）aspectjweaver-1.8.9.jar
3）aspectjrt-1.8.9.jar
3、分析：
1）当切面类的方法上通知注解直接输入切入点表达式时，没有报错。切面类代码如下：
import org.aspectj.lang.annotation.AfterReturning;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.hibernate.Transaction;import org.springframework.stereotype.Component;@Component("myTransaction")@Aspectpublic class MyTransaction extends HibernateUtil{ private Transaction transaction; @Before("execution(* net.fifteenho.spring.aop.annotation.PersonDaoImpl.*(..))") public void beginTransaction() { transaction = sessionFactory.getCurrentSession().beginTransaction(); } @AfterReturning("execution(* net.fifteenho.spring.aop.annotation.PersonDaoImpl.*(..))") public void commit() { transaction.commit(); }}
2）当切面类的方法上通知注解引入定义的切入点，报错error at ::0 can‘t find referenced pointcut。切面类代码如下：
import org.aspectj.lang.annotation.AfterReturning;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.hibernate.Transaction;import org.springframework.stereotype.Component;@Component("myTransaction")@Aspectpublic class MyTransaction extends HibernateUtil{ @Pointcut("execution(* net.fifteenho.spring.aop.annotation.PersonDaoImpl.*(..))") private void mypc(){} private Transaction transaction; @Before("mypc()") public void beginTransaction() { transaction = sessionFactory.getCurrentSession().beginTransaction(); } @AfterReturning("mypc()") public void commit() { transaction.commit(); }}
4、本人解决方法：aspectjweaver.jar替换较新的aspectjweaver-1.8.9.jar
5、报错原因：springAOP依赖jar版本过低。
