Spring Boot FAQ: Top Questions

@ConfigurationProperties is used to bind a group of related properties to a Java class, supporting structured configuration.

🗺️ Step-by-Step:

1. Create a POJO with matching fields and annotate it with @ConfigurationProperties.
2. Enable it using @EnableConfigurationProperties or @Component.

📥 Example:

@ConfigurationProperties(prefix = "app")
public class AppConfig {
  private String name;
  private String version;
}

🏆 Expected Output:

Maps app.name and app.version from configuration file.

🛠️ Use Cases:

• Cleanly managing grouped configuration properties.
• Making configuration reusable and injectable.
