LiteFlow从2.5.0版本开始，开始支持组件的切面功能，你可以通过2种方式进行

全局切面

全局切面是针对于所有的组件，进行切面。你只需要做如下实现即可：

public class CmpAspect implements ICmpAroundAspect {
    @Override
    public void beforeProcess(String nodeId, Slot slot) {
        YourContextBean context = slot.getContextBean(YourContextBean.class);
        //before business
    }

    @Override
    public void afterProcess(String nodeId, Slot slot) {
        YourContextBean context = slot.getContextBean(YourContextBean.class);
        //after business
    }
}

Aspect的切面

LiteFlow同时也支持了Spring Aspect的切面，你可以用@Aspect标注对任意包，任意规则内的组件进行切面

@Aspect
public class CustomAspect {

    @Pointcut("execution(* com.yomahub.liteflow.test.aop.cmp1.*.process())")
    public void cut() {
    }

    @Around("cut()")
    public Object around(ProceedingJoinPoint jp) throws Throwable {
        //do before business
        Object returnObj = jp.proceed();
        //do after business
        return returnObj;
    }
}
