Spring boot 2 Converting Duration java 8 application.properties

Question

I need to define Duration value (spring.redis.timeout) by application.properties.

I was trying to use one point defined in Spri

Answer 1

If your Spring-Boot version or its dependencies don't put ApplicationConversionService into context (and Spring-Boot doesn't until 2.1), you can expose it explicitly

@Bean
public ConversionService conversionService() {
    return ApplicationConversionService.getSharedInstance();
}

It invokes Duration.parse, so you may use PT3S, PT1H30M, etc in properties files.
