How can I know which dependency is missing in spring - spring

Question

When I run my spring project using STS, it gives me
org.springframework.beans.factory.UnsatisfiedDependencyException
How can I know which dependency is missing?
Can I know it by just seeing the error log?
For example, I met following error log
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

Answer 1

As the exception states (if you read past the first part), Spring expects to find a bean of class org.springframework.social.facebook.api.Facebook, but finds none.
When reading exceptions from Spring, always scroll either to the bottom (the root cause), or way out to the right.
