wrapper{
  distribuationUrl = "https://services.gradle.org/distributions/gradle-6.9.2-bin"

}

main class:

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
@EnableKafka
@EnableScheduling
public class SpringBootMainClassApplication {
    public static void main(String[] args) {
    
        SpringApplication.run(SpringBootMainClassApplication.class, args);
    }
}

application.properties

server.port=8080

Error: “ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean“.

enter image description here

Code running fine after adding below properties to application.properties.

spring.main.web-application-type=none

Application is working fine as console app without changing spring.main.web-application-type=none to properties with old version spring boot 2.2.7-RELEASE, Can you please help us to run application without adding new properties?

Answer 1

It is working fine, seems you gradle has lot of errors

Please use this gradle, always love your code as beautiful it could be like a painting :)
