AOP注解

1. xml 方式配置
<aop:config>
    <aop:aspectrefaop:aspectref="aspectDef">
        <aop:pointcutidaop:pointcutid="pointcut1"expression="execution(* com.test.spring.aop.pointcutexp..JoinPointObjP2.*(..))"/>
        <aop:before pointcut-ref="pointcut1" method="beforeAdvice" />
    </aop:aspect>
</aop:config>

2. 注解方式
@Component
@Aspect
public class AspectDef {
    //@Pointcut("execution(* com.test.spring.aop.pointcutexp..JoinPointObjP2.*(..))")
    //@Pointcut("within(com.test.spring.aop.pointcutexp..*)")
    //@Pointcut("this(com.test.spring.aop.pointcutexp.Intf)")
    //@Pointcut("target(com.test.spring.aop.pointcutexp.Intf)")
    //@Pointcut("@within(org.springframework.transaction.annotation.Transactional)")
    //@Pointcut("@annotation(org.springframework.transaction.annotation.Transactional)")
    @Pointcut("args(String)")
    public void pointcut1() {
    }
    @Before(value = "pointcut1()")
    public void beforeAdvice() {
        System.out.println("pointcut1 @Before...");
    }
