I have a Java class that needed an DBConnection Object
        
        
        
        I have another Java class that provided the DBConnection object
        
        
        I have these 2 choices:
        
        A) (non-spring)
            import ...DBConnection
            private DBConnection conn;
            
            con = new DBConnection(...);
            
        B) (spring)
            import ...DBConnection
            
            @Autowired
            private DBConnection conn;  <- Spring will construct this for me
