Spring application with embedded servlet container run error

Question

I am learning Spring and I have a problem. I have created standalone application (web service) which run in embedded servlet container. I use Intellij IDEA with gradle. When I run application from IDEA - all work fine. But when I have created jar file and run via console ("java -jar my.jar") I have got error (below). I was load official sample ( https://github.com/spring-guides/gs-rest-service ) and it's not work too (via running jar). I see this link but it not helped me: Spring Boot: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean

Please help

Something tells me you did not create your jar using gradle ? Perhaps you exported it from intellij ?

(1) Build with gradle:

You should build your jar using gradle (to create the jar using spring-boot-gradle-plugin ). Open a terminal at the root of your project and type:

$ gradle build
  ...

$ cd build/libs
$ java -jar yourjar.jar

(2) Export spring-boot jar from Intellij:
