title: Spring - how to debug to find specific use of spring's auto-wiring or a request parameter?
body: <p>Spring is auto-wiring in a request parameter - let's call it "bob". </p>
  
  <p>I don't know where nor how it is doing this, so I cannot debug it. What spring specific code (using intellij, so I can at lest set a conditional) would be appropriate to find where the auto-wiring of the request parameter is happening, so I can work out what the system is doing?</p>
