• Extracted configuration into multiple classes (seperating web and root...
• Added WebApplicationInitializer for security and update the one for the application.
• Removed web.xml (no need anymore)
• Removed spring-security.xml configuration
• Fixed Spring Framework and Spring Security Versions

Just noticed a minor glitch, due to the removal of the web.xml the maven build fails. Add the maven-war-plug and configure it to ignore the missing web.xml.

<build>
    <finalName>security-spr</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <failOnMissingWebXml>false</failOnMissingWebXml>
            </configuration>
        </plugin>
    </plugins>
</build>
