I am getting Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean even with @springbootapplication

This is my main class I am getting this error even though i am using the springbootApplication annotation that should autowire all dependecies

@EntityScan(basePackages = {"com.valentine.model","com.valentine.messenger"})
@SpringBootApplication(scanBasePackages = {"com.valentine.gram",
    "com.valentine.service", "com.valentine"})
@EnableJpaRepositories("com.valentine.dao")
@EnableTransactionManagement
public class MainApp {

    public static void main(String[] args) {
        SpringApplication.run(MainApp.class, args);
    }

}

Below is my stack trace and pom file , this is a modular project so i am posting the main pom file

As I know in spring boot there is no need to use extra annotation like 

@EntityScan(basePackages = {"com.valentine.model","com.valentine.messenger"})
@SpringBootApplication(scanBasePackages = {"com.valentine.gram",
    "com.valentine.service", "com.valentine"})
@EnableJpaRepositories("com.valentine.dao")

I think @SpringBootApplication is enough to handle all these annotation !

And I don't know why you using all these dependencies in spring boot 

     <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-web</artifactId>
                <version>${spring.version}</version>
            </dependency>

            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-test</artifactId>
                <version>2.0.4.RELEASE</version>
            </dependency>

            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-test</artifactId>
                <version>${spring.version}</version>
                <scope>test</scope>
            </dependency>

            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>
                <version>${spring.version}</version>
            </dependency>

            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-webmvc</artifactId>
                <version>${spring.version}</version>
            </dependency>
            <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
            <version>${spring.version}</version>
        </dependency>

All these dependencies are for spring MVC, not for spring boot ! And in spring boot there is no need to mention version for dependencies. Like 

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>${javax.servlet-api.version}</version>
     </dependency>

You can write only like this and spring boot will automatically handle this !

 <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
    </dependency>
