void advise(MethodInvocation invocation)
MethodInvocation.proceed()

The advice is free to inspect and even replace parameters. Most

replace any checked thrown exceptions. Some advice (for example, caching) may selectively decide to bypass the
invocation entirely, and instead invoke some other method or otherwise set a return value or thrown exception.invocation
