spring AOP 自定义注解使用

思维导图转载https://blog.****.net/wangpengzhi19891223/article/details/78131137/

spring 配置

<!--	注解支持-->
	<aop:aspectj-autoproxy/>
	<!-- aop -->
	<bean id="rightControlService" class="com.naro.erp.service.impl.RightControlService"></bean>

注解类

@Inherited
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)

public @interface RightControl {
    boolean verify();
}

切面类

@Aspect
@Component
public class RightControlService {

    Logger logger = LoggerFactory.getLogger(RightControlService.class);

    @Pointcut(value = "@annotation(com.naro.erp.util.RightControl)")
    public void pointCut(){}

//    @Before("pointCut() ")
//    public void before(JoinPoint  point) {
//        System.out.println("我是前置通知，我将要执行一个方法了");
//
//        //获取目标方法的参数信息
//        String className = point.getTarget().getClass().getName();
//        Object[] params = point.getArgs();
//    }
//
//    @AfterReturning(value = "pointCut() && @annotation(rightControl)",returning = "result")
//    public void after(RightControl rightControl,Object result) {

//    }

    @Around("pointCut()")
    public Object setCache(ProceedingJoinPoint point) throws Throwable {

        Object[] args = point.getArgs();//入参

        String methodName = point.getSignature().getName();//方法名
        AjaxResult ajaxResult= (AjaxResult)point.proceed();

        return ajaxResult;
    }


}

在需要使用注解的方法上打上注解即可
ProceedingJoinPoint 环绕通知专用
