since the companion object is essentially a singleton object created outside of the spring context - autowiring for it needs to be called manually.

You can grab a AutowireCapableBeanFactory from somewhere, e.g. by dependency injection or during SpringApplication setup and call beanFactoryInstance.autowireBean(PropHldr.Companion)

Thank you, may be Companion Object is a wrong idea... all I wanted to do is @Value("\${sipPropFile}") read from the application.properties file..... the below is also not working

@Configuration()

class Routing {

    @Value("\${sip.sipPropFile}")
    lateinit var sipPropFile: String

Also, for multi-line chunks of code you can use triple backticks 🙂

yep, thx

I think you have to define the path to the properties file for this to work. You can find an example in https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/context/annotation/Configuration.html, under the Using the @Value annotation heading

[visakha]

@PropertySource("classpath:application.properties") did the trick 🙂

@Tadas Giniotis the link you sent me helped

its a wonder when Spring Boot says -- its convention based and still makes you specify the properties file explicitly for the @Configuration annotation -- btw I was running the JUnit5 test case, this is where it originated

[tginiotis]

judging from this it should work without explicitly specifying the path - https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html
