Also you need to add "implements WebApplicationInitializer" to your application — Pradeep

@Pradeep added weblogic.xml and main class which implements WebApplicationInitializer — user1245524

Try to uncomment in your pom.xml:

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>
