In my case  the problem was I didn t had a Tomcat server separately installed in my eclipse  I assumed my Springboot will start the server automatically within itself   Since my main class extends SpringBootServletInitializer and override configure method  I definitely need a Tomcat server installed in my IDE   To install  first download Apachce Tomcat  version 9 in my case  and create server using Servers tab   After installation  run the main class on server   Run As - gt  Run on Server

My solution had to do with a bad dependency  I had    lt dependency gt     lt groupId gt org springframework boot lt  groupId gt     lt artifactId gt spring-boot-starter-web lt  artifactId gt     lt exclusions gt       lt exclusion gt         lt groupId gt org springframework boot lt  groupId gt         lt artifactId gt spring-boot-starter-tomcat lt  artifactId gt       lt  exclusion gt     lt  exclusions gt   lt  dependency gt    In my pom and I had to comment out the exclusion to get it working  It must look for this tomcat package for some reason

I was trying to create a web application with spring boot and I got the same error    After inspecting I found that I was missing a dependency  So  be sure to add following dependency to your pom xml file         lt dependency gt           lt groupId gt org springframework boot lt  groupId gt           lt artifactId gt spring-boot-starter-web lt  artifactId gt       lt  dependency gt

Apart from the possible solutions in other answers  it is also possible that somehow Maven dependency corruption has occurred on your machine  I was facing the same error on trying to run my  Web  Spring boot application  and it got resolved by running the following - mvn dependency purge-local-repository -DreResolve true  followed by mvn package  I came onto this solution looking into another issue where Eclipse wouldn t let me run the main application class from the IDE  due to a different error  similar to one on this SO thread - gt  The type org springframework context ConfigurableApplicationContext cannot be resolved  It is indirectly referenced from required  class files

You probably use this in your project      lt dependency gt       lt groupId gt org springframework boot lt  groupId gt       lt artifactId gt spring-boot-starter-webflux lt  artifactId gt   lt  dependency gt    in which case you ll have to also add      lt dependency gt       lt groupId gt org springframework boot lt  groupId gt       lt artifactId gt spring-boot-starter-web lt  artifactId gt   lt  dependency gt    and the magic happens     PS  that s because Spring will use by default web-MVC instead of web-flux when both are available

Case 1    SpringBootApplication annotation missing in your spring boot starter class   Case 2   For non web application  disable web application type in 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 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

My problem was the same as that in the original question  only that I was running via Eclipse and not cmd  Tried all the solutions listed  but didn t work  The final working solution for me  however  was while running via cmd  or can be run similarly via Eclipse   Used a modified command appended with spring config from cmd  start java -Xms512m -Xmx1024m  lt and the usual parameters as needed  like PrintGC etc gt  -Dspring config location  lt propertiesfiles gt  -jar  lt jar gt   I guess my issue was the spring configurations not being loaded correctly

I encountered this problem when attempint to run my web application as a fat jar rather than from within my IDE  IntelliJ    This is what worked for me  Simply adding a default profile to the application properties file   spring profiles active default   You don t have to use default if you have already set up other specific profiles  dev test prod   But if you haven t this is necessary to run the application as a fat jar
