我如何手动触发另一个类的方法周围的操作

Question

i have this configuration in application xml

<aop:config>
    <aop:aspect id="ruleAspect" ref="ruleInterceptor">
        <aop:pointcut expression="@within(....)" id="servicePointcut" />
        <aop:around pointcut-ref="servicePointcut" method="intercept"/>
    </aop:aspect>
</aop:config>

and if user trigger any action related my rules, that code runs

public Object intercept(ProceedingJoinPoint pjp) throws Throwable  {
    ...
    ...
    for (Rule rule :ruleList) {
       rule.doApply(pjp);
    }
}

and this code call rule class doApply method

public class Rule1 {

    @Override
    protected Object doApply(ProceedingJoinPoint invocation) {
        ...
        ...
    }

}

now, my question is that how can i trigger doApply method from another class manually with pjp parameter. i do not create pjp object because it is interface. is there anyway to call it?

Answer 1

I dont think that this is how you should think of aspects. they get invoked by the runtime and aren't meant to be manually callable.

Best dont even think of aspects as classes and methods at all.

what I would do to 'workaround this' is put the relevant logic from the aspect method into a static helper class method that you can then share between aop and manual invocation
