Comment

Mono. defer(monoSupplier) lets you provide the whole expression that supplies the resulting Mono instance. 
The evaluation of this expression is deferred until somebody subscribes. 
Inside of this expression you can additionally use control structures like Mono.
When you run Mono.just() it create immediately an Observable(Mono)and reuse it but when you use defer it doesn't create it immediately it create new Observable in every subscribe .
