Can some body help me whats wrong with the deployment process or pom.xml

Answer 1

You need to change the starter web dependency as:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-websocket</artifactId>
</exclusion>
</exclusions>
</dependency>
Also declare explicitly the starter tomcat dependency with provided scope.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
