Kotlin and spring boot data resource exception - spring

Question

I'm trying out kotlin and spring boot with spring data.
id("org.springframework.boot") version "2.1.8.RELEASE"
I have some schema-*.sql files in src/main/resources. I put this in my application.properties
spring.datasource.schema=/sql/schema-*.sql
I then made a small spring boot ApplicationRunner-based app (so set WebApplicationType.NONE) and these all get executed as expected and the app starts fine.
#SpringBootApplication
private class MainApp(): ApplicationRunner { ... }
fun main(args: Array<String>) {
runApplication<MainApp>(*args) {
webApplicationType = WebApplicationType.NONE
}
}
Now, when I change the above to WebApplicationType.SERVLET, I get the following:
Caused by: java.io.FileNotFoundException: ServletContext resource [/sql/] cannot be resolved to URL because it does not exist

This exception goes away and the http server seems to be fine when I omment out:
spring.datasource.schema=/sql/schema-*.sql
Any ideas what I'm supposed to change to make this work?

Answer 1

Try that spring.datasource.schema=classpath:sql/schema-*.sql.
