proxy - Spring AbstractAutoProxyCreator precedence

Question

I'm creating a framework, it automatically creates proxy for special interface by "org.springframework.aop.framework.autoproxy.AbstractAutoProxyCreator".

There is another framework, it can create the auto proxy for the same interface by the same technology too.

If the user use both of them, I hope the priority of my interceptor is lower. Howerver, all the AutoProxyCreator use the same order: "org.springframework.core.Ordered.LOWEST_PRECEDENCE", so it's impossible to specify the lower order such as "Ordered.LOWEST_PRECEDENCE + 1" for my auto proxy creator.

I tried to use this ugly solution

@Component
class MyAutoProxyCreator(
    // spring consider the "?" of kotlin type as optional dependency
    otherAutoProxyCreator: OtherAutoProxyCreator?
): AbstractAutoProxyCreator() {

    init {
      otherAutoProxyCreator?.let {
        // Improve the order of another auto proxy creator if it exists
        it.order = order - 1 
      }
    }

    override fun getAdvicesAndAdvisorsForBean(
        beanClass: Class<*>,
        beanName: String,
        customTargetSource: TargetSource?
    ): Array<Any> = TODO()
}

This works, but it's really ungly, and I don't know whether it has some side effects.

Is there any better solution, such as "declare precedence" of aspectj?
