Ordered
Normally starting with 0 or 1, with Ordered.LOWEST_PRECEDENCE
indicating greatest. Same order values will result in arbitrary
positions for the affected objects.
Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).
Note that order values below 0 are reserved for framework purposes. Application-specified values should always be 0 or greater, with only framework components (internal or third-party) supposed to use lower values.

public boolean isPerInstance()
Advisor
Note that this method is not currently used by the framework.
Typical Advisor implementations always return true
.
Use singleton/prototype bean definitions or appropriate programmatic
proxy creation to ensure that Advisors have the correct lifecycle model.

This represents the class part of a pointcut. Note that method matching doesn't make sense to introductions.
