</dependencies>Spring boot provides option to deploy the application as a traditional war file in servlet 3.x(without web.xml)supporting tomcat server.Please see spring boot documentation for this. I will brief what you need to do here.
step 1 : modify pom.xml to change the packaging to war:(that you already did)
<packaging>war</packaging>step 2 : change your dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>to
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>step 3 :modify your war name (if you need to avoid the version details appended with the war name) in pom.xml under <build> tag.
<build>
<finalName>web-service</finalName>
.....step 4 : run maven build to create war : clean install step 5 : deploy the generated war file web-service.war in tomcat and request url in browser http://<tomcat ip>:<tomcat port>/web-service/hello
