Run spring boot with jdk9 using jigsaw modules

Question

What\'s wrong with this application. I thought the mix of classpath jars and module jars are valid. For all jars not having an explicit module-info become an automatic modul

Answer 1

I assume spring.boot is an automatic module. An automatic module doesn't declare it dependences so you have to use --add-modules to ensure that any explicit modules needed are resolved. If spring.boot were an explicit module then I assume it would requires java.sql and you won't have this issue.
