The @Value annotation in Spring is a powerful tool used to inject values into fields, method parameters, and constructor arguments. It allows developers to externalize configuration, pulling data from .properties or .yml files, system environment variables, and even dynamic SpEL (Spring Expression Language) expressions. By supporting default values via the ${property:default} syntax, it ensures application resilience even when configurations are missing. This annotation is essential for creating decoupled, environment-agnostic applications that are easy to maintain and scale.
