IntelliJ IDEA: Webjars / Maven / Spring MVC - How do I import dependencies correctly and get them working?

So I am starting Java Web development and I just want some libraries to be imported into my IntelliJ project correctly using Maven. I stumbled upon using Webjars to import bootstrap and jquery, but I'm having big problems getting anything to work correctly. I wonder if anyone can help? Any suggestions are greatly appreciated.

My project currently has Maven and Spring MVC as supported frameworks. My pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <dependencies>
        <dependency>
            <groupId>org.webjars</groupId>
            <artifactId>bootstrap</artifactId>

                    <artifactId>jquery</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

            <artifactId>jquery</artifactId>
            <version>LATEST</version>
        </dependency>
    </dependencies>

</project>

My spring-config.xml:
