Spring boot interaction with Spring MVC + Spring S

I have finished my work on Spring-based(Spring-MVC) web application that also uses Spring Security, Hibernate, HSQLDB (and Maven of course). I was running my web app on Jetyy 9.x server integrated in IntelliJ IDEA, but now I need it to be packaged in single executable jar with embedded Jetty server.

People offered me to use Spring boot for embedding jetty purpose. So as I found out (because tried and read some info) Spring boot does not understand my xml configuration files that my app was using for configuring Spring-MVC and Spring Security.

How can I make all spring components interract with each other and what sould I do for that considering to my current (non spring boot project structure)?

The project structure and settings (non spring boot):

Code of configuration files:

hibernate.cfg.xml

        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <property name="connection.username">SA</property>
        <property name="connection.password"></property>

        <!-- JDBC connection pool (use the built-in) -->
