Currently, I am working on one project which provided me a lot of opportunities to learn about OAuth 2.0 and SAML and better understanding on which one to choose for SSO strategy. I am choosing this topic because most of the people get confused between these two. While they have some similarities but they are very different too and to put it one line. I would say “OAuth is not Single Sign-On” What is the difference between OAuth 2.0 and SSO? OAuth (Open Authorization) is a standard for authorization of resources. It does not deal with authentication. It allows secure authorization in a simple and standard method from web, mobile and desktop applications. If you try to log into Stack Overflow using Facebook, you’ll be redirected to Facebook’s website and will see something like the following: Once authenticated with Facebook, it will ask for Stack Overflow’s permission to access your resources l ike your name, Email id, Profile picture and so on. This is an authoriz...

I have seen people getting confused between singleton scope vs singleton design pattern. Basically, there is a bit difference between these two. Singleton scope: The spring support five different scopes and it is used to decide which type of bean instance should be returning from Spring container back to the caller. One of the scope is Singleton and the by default scope too. It returns a single bean instance per Spring IoC container. <bean id=”object1” class=“com.package.classname”/> When I said, single bean instance per spring Ioc Container i.e. you will always get the same object regardless of the number of call of the same bean but if you declare another bean for the same class then you will get another object for another bean. Let’s understand this with an example: <bean id=”object1” class=“com.package.classname”/> <bean id=”object2” class=“com.package.classname” scope=”prototype”/> <bean id=”object3” class=“com.package.classname”/...
