Error Creating Bean in Spring, dependency is declared in pom, spring cannot find class

I am trying to Inject a rest client into a class, but for some reason spring is failing to create the bean.

First off all, I have the dependency declared in my POM.XML, and the project builds fine:

    <dependency>
        <groupId>com.company</groupId>
        <artifactId>event-service-common</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <scope>provided</scope>
    </dependency>

But when spring tries to run, and create the bean I've declared in dispatcher-servlet.xml: 

<bean id="eventClient" class="com.company.client.EventServiceRestClient">
    <constructor-arg type="java.lang.String" value="http://localhost:9353"/>
    <constructor-arg type="java.lang.String" value="v1"/>
</bean>

I get the following stack of errors:

    SEVERE: Context initialization failed

If you declare thedependency as provided you are telling maven that the dependnecy will be available in runtime, but that jar will not be packaged in your project. You likely want a compile scope, which will be included in your classpath (for instance, packaged into a WAR).

<dependency>
    <groupId>com.company</groupId>
    <artifactId>event-service-common</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

See: Difference between maven scope compile and provided

You injected auditLogController in EventServiceRestClient, but you haven't define auditLogController

You need to define auditLogController
