i want dependency inject stockdaoimpl. can please tell me how can this. have been trying read of explainations complex. should use @autowired ? should put it? can please help.

you can inject through controller's constructor

class yourcontroller{    private final stockdao dao;    @autowired    public yourcontroller(stockdao dao){     this.dao = dao;   } }  

and stockdaoimpl has defined bean of course,

@bean public stockdao stockdao(){   return new stockdaoimpl(); } 

another way doing defining stockdaoimpl component
