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

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>

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