Spring Framework FAQ: Top Questions

Spring’s Environment abstraction provides access to environment variables, system properties, and application configuration (like application.properties).

📘 Features:

• Access to profiles and property sources.
• Useful for conditional configuration and context-aware logic.

📥 Example:

@Autowired
private Environment env;

public void printEnv() {
  System.out.println(env.getProperty("spring.datasource.url"));
}

🏆 Expected Output:

Prints the value of the datasource URL property from environment or config file.

🛠️ Use Cases:

• Reading config dynamically in code.
• Activating specific logic based on active profile.
