AOP+配置类
使用配置类扫描Bean对象类执行操作并被AOP切面类捕获，相较于之前的应用关键在于在配置类上添加@EnableAspectJAutoProxy注解
代码如下：
//主代码 src/main/java/org/example/App2.java
public class App2 {public static void main(String[] args) {AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(SpringConfig.class);Service service = ctx.getBean(Service.class);service.ServiceFunc();ctx.close();}
}
//配置类 src/main/java/org/example/config/SpringConfig.java
@Configuration
@ComponentScan("org.example")
@EnableAspectJAutoProxy
public class SpringConfig {}//AOP切面类 src/main/java/org/example/AOP/RecordTimeAspect.java
@Aspect
@Component
@Slf4j
public class RecordTimeAspect {@Pointcut("execution(* org.example.Service.impl.*.*(..))")private void pt() {}@Around("pt()")public Object recordTime(ProceedingJoinPoint pjp) throws Throwable {long beginTime = System.currentTimeMillis();Object result = pjp.proceed();long endTime = System.currentTimeMillis();log.info("This Function cost Time: {}ms",endTime-beginTime);return result;}
}
