1）AOP拦截器（面向切面编程），主要功能是对业务层的方法调用进行拦截处理，SpringBoot默认情况下并没有配置AOP拦截器。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
2）定义AOP程序类，对业务方法进行拦截
/** * aop程序类，对业务方法进行拦截，本例使用环绕通知处理 * * @author relax * @version 1.0 * @date 2021/8/24 10:34 */ @Aspect @Component public class ServiceAspect { @Around("execution(* com.python.music..service..*.*(..))") public Object aroundInvoke(ProceedingJoinPoint point) throws Throwable { System.out.println("[***service-before***]执行参数" + Arrays.toString(point.getArgs())); //进行具体业务调用 Object obj = point.proceed(point.getArgs()); System.out.println("[***service-after***]返回结果" + obj); return obj; } }
