Your missing the 'spring-boot-autoconfigure' jar, not sure why. You can check if it is in .m2 directory. If yes I would delete it and reimport the project. — mh-dev
I tryed it it didn't worked. I tried the same code in eclipse in eclipse there is no error but is STS it is giving error. — Archit Aggarwal
@Archit, Linking my answer (stackoverflow.com/questions/39245732/…) to this question. — Praveen Kumar K S
Does it compile if you run "mvn clean package" from the command line? — Christophe L

Your pom looks almost correct, but few things to note

No need to add dependency 'javax.servlet-api', it is available from 'spring-boot-starter-web'
And you probably you may be missing the 'spring-boot-maven-plugin', it is not compulsory but you may want that in your project. Where it provides some easy maven goals for you to run.

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

if your running eclipse you can generate your .classpath files just as usual mvn eclipse:eclipse, once done your ide should look fine

then mvn spring-boot:run should set your application running
