Spring Boot FAQ: Top Questions

@Conditional is used to conditionally register a Spring bean depending on the result of a specified condition.

🗺️ Steps:

1. Define a class implementing Condition.
2. Annotate bean method or class with @Conditional(MyCondition.class).

📥 Example:

public class OnWindowsCondition implements Condition {
  public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
    return System.getProperty("os.name").contains("Windows");
  }
}

🏆 Expected Output:

Bean is registered only on Windows OS.

🛠️ Use Cases:

• Load beans based on environment, classpath, or property.
• Enable/disable configuration features conditionally.
