First, the range of @resource is larger than the @autowire.
First find all the beans that meet the criteria by type
Determine the bean length, if not, to determine if an exception is thrown based on the required property in @autowired (default is True)
If more than one, then try to find the optimal one, if the optimal is not found, then throw an exception
If there is only one, use this bean directly
If @autowire is marked on the setter method, the default is to inject b
