Hello, I am trying to read properties but it never returns the correct value.

This is what I use

@Component
@ConfigurationProperties
@PropertySource("classpath:app.properties")
class AppProperties {
    lateinit var mongoUri: String
    lateinit var manticoreEndpoint: String
    lateinit var manticorePlatform: String
    lateinit var manticoreUsername: String
    lateinit var manticorePassword: String
    lateinit var internalToken: String
}

My properties look like

mongo-uri=""
mantictore-endpoint=""

I also added @EnableConfigurationProperties.

I missed something? Thanks for your help.

does it help if you replace @Component with @Configuration

[Tristan Caron]

I just tried, the result is the same 😞

Try annotating the properties with @Value("${mongo-uri}"), etc

[Matheus]

(Are they supposed to bind just by name?)

[Jukka Siivonen]

The one idea of @ConfigurationProperties is to get rid of using @Value, @ConfigurationProperties is actually a Spring Boot feature and not included in Spring Core

[Tristan Caron]

Even with @Value it doesn't work.

[Jukka Siivonen]

Maybe you should try some simple value first with prefix like

app.foo = value

[Jukka Siivonen]

Then use

@ConfigurationProperties(prefix = "app")

[Jukka Siivonen]

lateinit var foo: String

[Jukka Siivonen]

also try leaving out

@PropertySource("classpath:app.properties")

and use application.properties which should be the default

[Tristan Caron]

Hmm I applied all your suggestion, it still not working.

[Jukka Siivonen]

strange

[Tristan Caron]

I even tried to use Environment with env.getProperty("mongo-uri"), I could not get the value.

[Tristan Caron]

Maybe it's not related to Kotlin then. I will ask on StackOverflow then. Thanks for your help.
