How to Access Properties from application.properties in Spring Boot?

Accessing Properties from application.properties in Spring Boot

Spring Boot provides a convenient way to access values defined in the application.properties file. This is useful for storing configuration information that can be easily modified without recompiling the application.

Accessing a Specific Property

To access a specific property, use the @Value annotation along with the property name enclosed in ${}. For example, to access the userBucket.path property:

@Value("${userBucket.path}")
private String userBucketPath;

This will automatically inject the value of the userBucket.path property into the userBucketPath field. You can then use this field in your application code as needed.

Additional Spring Boot Configuration

Spring Boot also supports externalized configuration through various means. The Externalized Configuration section of the Spring Boot documentation provides detailed information on the available options:

• [Environment Property Sources](https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-external-config-environment-properties)
• [Property Sources](https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-external-config-property-sources)
• [Configuration Properties](https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-external-config-configuration-properties)
• [YAML Configuration](https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-external-config-yaml-support)

By leveraging these features, you can easily manage and access configuration values from a variety of external sources, including the application.properties file.
