I could set the default property value to an empty String as the example under, but still not quite optimal.

```
@Value("\${email.address.override:}")
```

if u could set `:default` then there is no need for `String? = null`

btw: `@Value ` is very good to wire with constructor. Is there a reason why u don't use this way?

```
@Service
class FileService(
@Autowired val storage: Storage,
@Value("\${files-topic:default-topic}") val filesTopic: String
) {}
```

Thanks <@U2BUQ9KJL>! Is there any way to set the default value to null? If i use :null i actually get the String "null" instead of NULL

pls reply will it works for you or not - cos I`m also interesting in that

<@U2BUQ9KJL> you can write it like this: ```@Value("\${email.address.override:#{null}}")``` in order to set the default to null
