SEVERE: Context [/SpringMVCPractice1] startup failed due to previous errors - spring-mvc

Question

I am practicing Spring MVC web application (Spring4) using Java config files rather than XML config files. the Tomcat Server is not able to start the web application. during starting Tomcat I've received the following error in the console , but there is not previous message on the console
SEVERE: Context [/SpringMVCPractice1] startup failed due to previous errors
I don't have web.xml file and dispatcher-servlet.xml as it is java file config
here are whole log from console and whole source code
