• getOrCreate

  public <T> T getOrCreate(Class<T> type)

  Hands over an existing bean or tries to instantiate one with the following rules:

  • If exactly one bean is present in the context, it returns this bean.
  • If no bean is present, it tries to instantiate one.
  • If more than one bean is present, it tries to instantiate one but in case of a Bean instantiation exception this exception is catched and rethrown with a hint. Reason for this is, that users may expect it to "use" a bean but have multiple in the context. So the hint helps them find the problem.
