I added this config into application.yml

 spring:
    main:
      web-application-type: none

or extends SpringBootServletInitializer the MainClass

but nothing changed

I added also

@Bean
    public ServletWebServerFactory servletWebServerFactory() {
        return new TomcatServletWebServerFactory();
    }

in the configClass first and second in the mainClass. But no changes.

CodePudding user response：

I got this issue due to corrupted dependency. To fix this issue, you can run below command from the terminal

mvn dependency:purge-local-repository -DreResolve=true; mvn clean package;

Or remove all files from the repository folder .m2/repository and update your maven project

CodePudding user response：

just added

 spring:
    main:
      web-application-type: none

in application.yml of test
