Unable to initialize context, application context root is already present

Question

Unable to initialize context, application context root is already present

In my last question, I got an answer to create ContextLoaderListener

. I am looking for how to add ContextLoaderListener

without applicationContext.xml

. I found Quick Start - Hello Spring Security enter link here . After adding, I get error information

Caused by: java.lang.IllegalStateException: Cannot initialize context because there is already a root application context present - check whether you have multiple ContextLoader* definitions in your web.xml!

But I am not setting up ContextLoaderListener in web.xml

web.xml
