Answer 1

If you run it successfully using command line gradle bootRun, while packaging it with command line gradle jar to jar file in order to run it with command line java -jar build/libs/demo.jar, unfortunately, it failed with Exception: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean, in this case, you need to use task bootRepackage of gradle plugin spring-boot to generate special runnable jar.

• setup 1

  $ gradle clean bootRepackage

• setup 2

  $ java -jar build/libs/demo.jar
