I had the same issue get value for my property in my service class. I resolved it by using @ConfigurationProperties instead of @Value.

1. create a class like this:

    import org.springframework.boot.context.properties.ConfigurationProperties;

    @ConfigurationProperties(prefix = "file")
    public class FileProperties {
        private String directory;

        public String getDirectory() {
            return directory;
        }

        public void setDirectory(String dir) {
            this.directory = dir;
        }
    }

2. add the following to your BootApplication class:

    @EnableConfigurationProperties({
        FileProperties.class
    })

3. Inject FileProperties to your PrintProperty class, then you can get hold of the property through the getter method.
