Thanks in advance !

How are you creating the jar? Also I strongly suggest using the spring-boot-starter-* dependencies instead of defining everything yourself. — M. Deinum

I figured out the cause , the dependencies were not added in the jar that was created !! @Deinum . i was running maven goal : mvn clean install Thanks for your response and feedback on using spring-boot-starter ! — Shreesha N

Did you try to following things? stackoverflow.com/a/52738836/9243717 — jaragan

You need to set build attribute.

<build>
  <plugins>
    <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
    </plugin>
  </plugins>
</build>

If you follow this document carefully , you should be able to build the jar file and run the app , I was running into the same issue searched various options nothing worked, finally , I rewrote the pom file and ran the below command mvn package && java -jar target/jarname.jar

It worked !

                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

This will take care of the packaging. Believe me
