Could not autowire field using @Autowired annotation

I tried to autowire the fields from property file. I just keep the property file in class path.

@Autowired
public BlankDisk(@Value("${disk.title}") String title, @Value("${disk.artist}") String artist) {

        this.title = title;
        this.artist = artist;
    }

app.properties

disc.title=New Songs
disc.artist=Illayarajah

I have written the above code to autowire the fields. But I am getting below exception.

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'autowireDemo': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.springinaction.autowiring.BlankDisk com.springinaction.autowiring.AutowireDemo.blankDisk; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'disk.title' in string value "${disk.title}"

Can anyone please suggest why I am getting this issue?

I had a similar issue, and I found the error to be in the discrepancies between my src/main/resources/application.properties

src/test/resources/application.properties
The property I was trying to inject was not in the latter file and when SpringBoot tried to run the test as part of the build, it could not find the property.

If you still get the exception after changing the spelling mistake, please make sure if you have added @PropertySource("classpath:application.properties") on top of the configuration class
