Exception starting filter springSecurityFilterChain - org.springframework.beans.factory.NoSuchBeanDefinitionException - spring

Question

I am new with spring. I am trying to use Spring Security to have authentication using MySQL, I get this error:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'springSecurityFilterChain' is defined
By judging from similar questions I think the security config file is not loaded.
my config file is in src/main/resources/spring-security.xml and I include it in awt.project.init.WebAppConfig:
#Configuration
#EnableWebMvc
#EnableTransactionManagement
#ComponentScan("awt.project")
#ImportResource("classpath:spring-security.xml")
public class WebAppConfig {
....
}
Here is the web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

I tried to also include the spring-security.xml in contexConfiguration as classpath:spring-security.xml but still I get the same problem.
Here is the spring-security.xml

I might be wrong, but if you use AnnotationConfigWebApplicationContext and specify only a package name in contextConfigLocation, Spring will scan that package only for classes with a stereotype annotation (#Component, #Controller, #Service, etc), so your WebAppConfig is basically ignored. Try giving the fully qualified name of WebAppConfig as contextConfigLocation.
