自定义注解进行aop拦截

首先自定义一个注解,将注解贴在需要拦截的方法上

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface aop {
    String name();
}

配置AOP

//使用javaconfig配置
@Configuration
// 使用CGLIB代理
@EnableAspectJAutoProxy(proxyTargetClass = true)
@ComponentScan("com.ssm.Aop")
public class AopConfig {
    
}

编写切面

@Component
@Aspect
public class AopTest {

	// 自定义注解所在位置
    @Pointcut("@annotation(com.ssm.controller.aop)")
    public void print() {
    }

    @Around("print()")
    public Object around(ProceedingJoinPoint pjp) throws Throwable {

        MethodSignature signature = (MethodSignature) pjp.getSignature();

        Method method = signature.getMethod();

        aop aop = method.getAnnotation(aop.class);
        String s = aop.name();
        System.out.println(s);

        Object o = pjp.proceed();
        System.out.println(pjp.getSignature().toShortString());
        Object[] args = pjp.getArgs();


        System.out.println("获取被代理的对象" + pjp.getTarget());
        System.out.println("获取代理的对象" + pjp.getThis());

        return o;
}
