spring - ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean

Question

I have written a spring batch application using Spring boot. When I am trying to run that application using command line and classpath on my local system it is running fine. However, when I tried to run it on linux server it is giving me following exception

Unable to start web server; nested exception is
org.springframework.context.ApplicationContextException: 
Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.

Below is the way I am running it:

java -cp jarFileName.jar; lib* -Dlogging.level.org.springframework=DEBUG -Dspring.profiles.active=dev -Dspring.batch.job.names=abcBatchJob com.aa.bb.StartSpringBatch > somelogs.log

Answer 1

Case 1:

@SpringBootApplication annotation missing in your spring boot starter class.

Case 2:

For non-web applications, disable web application type in the properties file.

In application.properties:

spring.main.web-application-type=none

If you use application.yml then add:

  spring:
    main:
      web-application-type: none

For web applications, extends *SpringBootServletInitializer* in the main class.

@SpringBootApplication
public class YourAppliationName extends SpringBootServletInitializer{
    public static void main(String[] args) {
        SpringApplication.run(YourAppliationName.class, args);
    }
}

Case 3:

If you use spring-boot-starter-webflux then also add spring-boot-starter-web as dependency.
