spring AOP配置类

//实现MethodInterceptor接口。(扮演Advice通知的角色)
public class MyInterceptor implements MethodInterceptor {

    @Override
    public Object invoke(MethodInvocation invocation) throws Throwable {
        System.out.println(invocation.getMethod() + "==方法执行前==");
        Object proceed = invocation.proceed();
        System.out.println(invocation.getArguments() + "--方法执行后--");
        return proceed;
    }

}

@Configuration
public class MyInterceptorConfig {

//切点
    public static final String traceExecution = "execution(* cn.qlq.service..*.*(..))";

    @Bean
    public DefaultPointcutAdvisor defaultPointcutAdvisor2() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression(traceExecution);

        // 配置增强类advisor
        DefaultPointcutAdvisor advisor = new DefaultPointcutAdvisor();
        advisor.setPointcut(pointcut);
        MyInterceptor interceptor = new MyInterceptor();
        advisor.setAdvice(interceptor);
　　　　　advisor.setOrder(1);
        return advisor;
    }

}

另外还有@aspect实现
