Spring Boot attempts to coerce the external application properties to the right type when it binds to the @ConfigurationProperties beans. If you need custom type conversion, you can provide a ConversionService bean (with a bean named conversionService)

See: https://docs.spring.io/spring-boot/docs/2.0.4.RELEASE/reference/htmlsingle/#boot-features-external-config-conversion

Create new ApplicationConversionService bean (it must be named conversionService ). Here you are my code tested with Spring boot 2.0.4:

@Configuration
public class Conversion {

@Bean
public ApplicationConversionService conversionService()
{
    final ApplicationConversionService applicationConversionService = new ApplicationConversionService();
    return applicationConversionService;
}

Here you are an example project using this approach:
