Spring 5 Design Patterns

Implementing the Proxy design pattern

Let's look into following code to demonstrate the Proxy pattern.

Create a Subject.

Following is the Account.java file:

    public interface Account { 
      void accountType(); 
    } 

Create a RealSubject class that implements Subject, let's see the following class as RealSubject class for the Proxy design pattern.

Following is the SavingAccount.java file:

    public class SavingAccount implements Account{ 
       public void accountType() { 
          System.out.println("SAVING ACCOUNT"); 
       } 
    } 

Create a Proxy class which implements Subject and having the Real Subject

Following is the ProxySavingAccount.java file:

 package com.packt.patterninspring.chapter2.proxy.pattern; import com.packt.patterninspring.chapter2.model.Account; import com.packt.patterninspring.chapter2.model.SavingAccount; ...
