How Can I Access application.properties Values in My Spring Boot Application?

Accessing Values from application.properties in Spring Boot

In Spring Boot applications, you may need to access configuration values defined in the application.properties file. This article explains how to access these values and use them in your program.

Accessing Property Values with the @Value Annotation

To access a property value in your Spring-managed object (such as a service or controller), use the @Value annotation. For instance, to access the userBucket.path property, you can add the following annotation to the appropriate class:

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

This annotation will automatically populate the userBucketPath field with the value defined in the application.properties file.

Logging Configuration Example

The example provided in the question demonstrates accessing logging-related properties. To access these properties, you can use the @Value annotation within your logging-related class:

@Value("${logging.level.org.springframework.web}")
private String springWebLogLevel;

@Value("${logging.level.org.hibernate}")
private String hibernateLogLevel;

Externalized Configuration in Spring Boot

For more information on externalized configuration options, refer to the Spring Boot documentation's section on [Externalized Configuration](https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-external-config).
