[java] How to access a value defined in the application.properties file in Spring Boot

You can use the @Value to load variables from the application.properties if you will use this value in one place, but if you need a more centralized way to load this variables @ConfigurationProperties is a better approach.

Additionally you can load variables and cast it automatically if you need different data types to perform your validations and business logic.

application.properties
custom-app.enable-mocks = false

@Value("${custom-app.enable-mocks}")
private boolean enableMocks;
