Spring Boot - Dependency Injection with @Qualifer & Network Calls Using RestTemplate
Spring Boot is extremely flexible when it comes to component scanning and dependency injection. For instance, for our BankDataSource interface, we may want to provide different implementations. Spring Boot’s @Qualifier annotation allows to easily choose a specific implementation at the injection point.
Also, in this tutorial we fetch some actual bank data from a node in the actual TheNewBoston digital currency chain. Spring Boot makes it very easy to perform REST API calls using its RestTemplate.
