Servlet.init() для сервлета [dispatcher] выбросил исключение

Начинаю изучать spring security, выбрасывается исключение, в чем может быть проблема?

MyConfig:

package com.zaurtregulov.spring.security.configuration;
 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.View;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
 
@Configuration
@ComponentScan(basePackages = "com.zaurtregulov.spring.security")
@EnableWebMvc
public class MyConfig {
    @Bean
    public ViewResolver viewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/view/");
        resolver.setSuffix(".jsp");
 
        return resolver;
    }
}

MyWebInitializer:

package com.zaurtregulov.spring.security.configuration;
 
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
 
public class MyWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }
 
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{MyConfig.class};
    }
 
    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

MySecurityInitializer:

package com.zaurtregulov.spring.security.configuration;
 
import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;
 
public class MySecurityInitializer extends AbstractSecurityWebApplicationInitializer {
}

MySecurityConfig:

package com.zaurtregulov.spring.security.configuration;
 
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.User.UserBuilder;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
 
@EnableWebSecurity
 
public class MySecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        UserBuilder userBuilder = User.withDefaultPasswordEncoder();
 
        auth.inMemoryAuthentication()
                .withUser(userBuilder.username("matvey").password("matvey").roles("EMPLOYEE"))
                .withUser(userBuilder.username("ivan").password("ivan").roles("HR"))
                .withUser(userBuilder.username("matvey").password("matvey").roles("MANAGER", "HR"));
    }
}

В итоге вместо страницы с аутентификацией вылетает исключение с месседжем Servlet.init() для сервлета [dispatcher] выбросил исключение.
