I ran into this a couple times a quarter. This time I had a minimal change summary in my git diff and tracked the problem to a reset classpath (missing my WEB-INF/lib dependency) in eclipse. This seems to occur any time I pull in or pull out parent/sibling maven projects.

There are mentions of adding your spring jars to the tomcat web container lib - this is ok and is the way most EE servers run. However be aware that by placing spring higher in the classloader tree on tomcat you will be running higher than the classloader level of your war context. I recommend you leave the libs in a per/war lower level classloader.

We see the following after a truncated .classpath after a structural project change in eclipse.

Dec 18, 2016 11:13:39 PM org.apache.catalina.core.StandardContext listenerStart
SEVERE: Error configuring application listener of class org.springframework.web.context.request.RequestContextListener
java.lang.ClassNotFoundException: org.springframework.web.context.request.RequestContextListener

My classpath was reset and the WEB-INF/lib dependency was removed.

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
    <attributes>
        <attribute name="maven.pomderived" value="true"/>
        <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
    </attributes>
</classpathentry>

put back

<attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>

and you will be OK.

thank you /michael

When I look at the solutions  it seems the problem is always something that prevents the spring library to be loaded   It could be a dependency problem or a deployment problem   In my case  it was the maven repository that somehow got corrupt   What solved the problem was to remove the folder  C  Users my name  m2 repository  and rebuild

One quick solution I prefer which I suited most for this situation is simply delete  metadata folder of your work space and import your projects again  If you try all other option it wont guarantee the success  Sometimes the above solutions work sometime you will spend your precious hours to fix this configuration   One day i decided to clean my work station I arranged the projects to their suitable folders according to different clients  As a result all got messed up  After spending a whole day it did not end up in a fixed work space  Next day I simply deleted the  metadata folder of the work space and imported all the projects again  Bingo all set

Actually this is a problem of Tomcat  Just go to  lib  folder of your project and copy your all  Spring  related jars into this  Refresh your project and you are all good to go  This problem sometime persists because tomcat is unable to locate Spring core classes
