AOP记录方法的执行时间

作用AOP监控方法的运行时间如下：

@Component

@Aspect

public class LogAop {

    private Logger log = LoggerFactory.getLogger(getClass());

    //切面

    private final String CUT = "execution (* com.wey.spring.controller.*Controller.*(..))";

    @Around(CUT)

    public Object around(ProceedingJoinPoint pjp) throws Throwable {

        Object[] args = pjp.getArgs();

        Object result = null;

        long start = System.currentTimeMillis();

        try {

            result = pjp.proceed(args);

        }

        catch (Exception e) {

            throw e;

        }

        long end = System.currentTimeMillis();

        log.info("" + pjp.getTarget().getClass() + "." + pjp.getSignature().getName() + " 方法用了 " + (end - start)

                + "毫秒");

        return result;

    }

}

注解方式配置开启动态代理：

@EnableAspectJAutoProxy

XML配置方式的

<aop:aspectj-autoproxy proxy-target-class="true"/>
