Spring 5 Design Patterns

Sample implementation of FactoryBean interface

Suppose you have a TransferService class whose definition is thus:

    package com.packt.patterninspring.chapter4.bankapp.service; 
    import com.packt.patterninspring.chapter4.     bankapp.repository.IAccountRepository; 
    public class TransferService { 
      IAccountRepository accountRepository; 
      public TransferService(IAccountRepository accountRepository){ 
        this.accountRepository = accountRepository; 
      } 
      public void transfer(String accountA, String accountB, Double       amount){ 
        System.out.println("Amount has been tranferred"); 
      } 
    } 

And you have a FactoryBean whose definition is thus:

 package com.packt.patterninspring.chapter4.bankapp.repository; import org.springframework.beans.factory.FactoryBean; public class AccountRepositoryFactoryBean ...
