Annotate conditional field paper

hi guys welcome to simple programming in this video let us see how to make use of at the rate of conditional and conditioned interface available in spring in some scenarios you might need to validate a verify something before loading a bean in the context how will you implement these scenarios in spring you can make use of the spring condition spring conditions are heavily used in message driven micro services even to run micro services etc or let us say that you want to control the loading of a bean in a specific environment you might think we can use at a rate of profiles for this yes that is correct but profile annotation is restricted to write conditional checking based on three different properties at the rate of conditional annotation does not have this restriction with the help of condition interface you can write a condition to check a pre different property or you can write your own condition own logic inside it so this is a major difference between at the rate of profile and at the rate of conditional and conditional interphase what if you have some use a different logic associated with loading a beam that has some if-then-else statements associated with that logic you might want to use other rate of conditional and condition interface in those scenarios let us see how to make use of these two with an example now I have a simple Springwood application here so let me quickly show you the controller the controller is nothing fancy it's going to be a risk controller and I have Auto wide the risk template here and it's going to you know request a string from a different service and then it's going to return the string the condition that I am going to uses I'm going to set up a value in my property file and if that value is true then this rest template being should be loaded if not then this should not be loaded okay so let us quickly take a look at our condition class so the condition class is going to implement the spring condition interface and once you implement that you would be overriding the matches my so inside this max just method you can have your own implementation here in this case I'm going to you know get the property a paid or student or generate token from my property file and if the token values hello then I am going to say this condition is true if that value is not alone then it would be this condition is false and I would not allow this beam to be loaded in the context so let us quickly take a look at our configuration the configuration class as the first template beam in it and if you notice on top of the rest template I am annotated it with at the rate of conditional so I have a condition as verify student dot...
