When ever i add spring security configuration in web.xml i get the error "No WebApplicationContext found: no ContextLoaderListener registered?" - spring

Question

When i add the following into web.xml
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<param-name>contextAttribute</param-name>

</filter-mapping>
I am getting the following error
java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?
org.springframework.web.filter.DelegatingFilterProxy.doFilter(DelegatingFilterProxy.java:251)
Could someone help me here?

Answer 1

I see that you didn't attached your entire web.xml.
From the exception you got I assume you did not configure Spring IoC container which is an integral part of Spring.
You have several ways to do so, here is one way (goes in your web.xml):
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
You can start with an empty applicationContext.xml, here is an example:
<?xml version="1.0" encoding="utf-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:flex="http://www.springframework.org/schema/flex" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
