基于配置文件的方式配置AOP

<aop:config>

配置切点表达式

<aop:pointcut expression="execution(* 类名.*（int,int）) id="pointcut"/>

配置切面及通知

<aop:aspect ref="loggingAspect(上文已经配置过的切面的bean)" order="1（优先级）">

<aop:before method="beforeMethod(方法名)" pointcut-ref="pointcut(上文的切点)"

<aop:after-throwing/>异常抛出

<aop:after-returning/>返回通知

<aop:around/>环绕，全部输出

</aop:aspect>

</aop:config>

基于注解的方式配置AOP

切面

@Order(2)优先级

@Component

@Aspect

public class LoggingAspect{

@Before("execution(类名.*(..))")

public void beforeMethod(JoinPoint joinPoint){}

@AfterReturning(value="execution(public int com.yl.spring.aop.ArithmeticCalculator.*(..))", returning="result")

public void afterReturning(JoinPoint joinPoint, Object result) {}

@AfterThrowing(value="execution(public int com.yl.spring.aop.ArithmeticCalculator.*(..))", throwing="ex")

}
