How to create spring boot project from existing maven project

Question

I have created a maven project in eclipse and I want to deploy it on a server(tomcat I guess). I believe this can be done via spring boot. My question is this: this project has imported several jar files located on my PC and has another project that is in the workspace in its build path. I worry that during the integration(turning it into maven) I might lose all the dependencies. What is generally the best way to import jar files to a project and how to add another project in its build path? Please comment with any other specifications that you need.

This is the pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"

For integrating local jar files in your maven project, have a look to: How to add local jar files to a Maven project?

To add Spring Boot to your pom.xml, you need to add the following (from this doc

<!-- Inherit defaults from Spring Boot -->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.5.RELEASE</version>
</parent>

<!-- Add typical dependencies for a web application -->
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

<!-- Package as an executable jar -->
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

i think you have a bit of a misconception of what spring.boot actually is.

Spring-boot is a complete eco system for building a microservice integrated with a lot of well used java libraries.

Your pom seams to be a fully written application made to be deployed onto an empty tomcat server. Spring-boot is not an empty tomcat, spring-boot is an application/framework that uses tomcat under the hood.

What you need is to go over to http://tomcat.apache.org/ and download the tomcat server and then google how to setup/start tomcat in your choice of IDEA. After that is done you need to open the maven project in your IDEA of choice and deploy it to the tomcat server.

Using eclipse/intellij there are several tutorials on the internet explaining how to install and setup tomcat. And also tonnes of tutorials in how to import maven projects and build and deploy to tomcat.
