Spring Boot: @Value returns always null

Question

I would like to use a value from application.properties file in order to pass it in the method in another class. The problem is that the value returns always

You can't use @Value on static variables. You'll have to either mark it as non static or have a look here at a way to inject values into static variables:

EDIT: Just in case the link breaks in the future. You can do this by making a non static setter for your static variable:

@Component
public class MyComponent {

    private static String directory;

    @Value("${filesystem.directory}")
    public void setDirectory(String value) {
        this.directory = value;
    }
}

The class needs to be a Spring bean though or else it won't be instantiated and the setter will be not be accessible by Spring.
