Spring Boot with JSF; Could not find backup for factory javax.faces.context.FacesContextFactory

I'm having some problems with Spring Boot and JSF. The servlet appears to start up correctly, but when I attempt to access a resource I get the following exception

java.lang.IllegalStateException: Could not find backup for factory javax.faces.context.FacesContextFactory.

My Application class is as follows

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    @Bean
    public FacesServlet facesServlet() {
        return new FacesServlet();
    }

    @Bean
    public ServletRegistrationBean facesServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(
            facesServlet(), "*.xhtml");
        registration.setName("Christmas");
        return registration;
    }

    @Bean
    public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() {
        return new ServletListenerRegistrationBean<ConfigureListener>(
            new ConfigureListener());
    }
}

I have no web.xml or faces-config.xml, and my pom.xml is as follows

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependency>

        <!-- JSF 2 -->
        <dependency>
            <groupId>com.sun.faces</groupId>
            <artifactId>jsf-api</artifactId>

            <version>2.1.11</version>
        </dependency>
    </dependencies>

</project>

I have a suspicion that there are some conflicts in the dependencies relating to the jsf api, but I can't seem to figure out where. Any help on fixing this issue would be greatly appreciated.

To get JSF working on Spring Boot without a web.xml or faces-config.xml you need to force it to load its configuration files via an init parameter on the ServletContext. An easy way to do that is to implement ServletContextAware:

public class Application implements ServletContextAware {

    // ...

    @Override
    public void setServletContext(ServletContext servletContext) {
        servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());           
    }
}

JSF's ConfigureListener also has a dependency on JSP, so you'll need to add a dependency on Jasper to your pom:

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
</dependency>

It's not directly related to your problem, but you don't need to declare FacesServlet as a bean. The ServletRegistrationBean is sufficient.

This leaves Application.java looking as follows:

import javax.faces.webapp.FacesServlet;
import javax.servlet.ServletContext;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.context.embedded.ServletListenerRegistrationBean;
import org.springframework.boot.context.embedded.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.context.ServletContextAware;

import com.sun.faces.config.ConfigureListener;

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application implements ServletContextAware {

    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }

    @Bean
    public ServletRegistrationBean facesServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(
            new FacesServlet(), "*.xhtml");
        registration.setLoadOnStartup(1);
        return registration;
    }

    @Bean
    public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() {
        return new ServletListenerRegistrationBean<ConfigureListener>(
            new ConfigureListener());
    }

    @Override
    public void setServletContext(ServletContext servletContext) {
        servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());       
    }
}

probably you forget add listener com.sun.faces.config.ConfigureListener.class :

  @Bean
    public ServletContextInitializer servletContextInitializer() {

        return sc -> {
            ***sc.addListener(com.sun.faces.config.ConfigureListener.class);***
            sc.setInitParameter("com.sun.faces.expressionFactory", "com.sun.el.ExpressionFactoryImpl");
            sc.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
            sc.setInitParameter("facelets.DEVELOPMENT", Boolean.TRUE.toString());
            sc.setInitParameter("javax.faces.DEFAULT_SUFFIX", ".xhtml");
            sc.setInitParameter("javax.faces.FACELETS_LIBRARIES", "springsecurity.taglib.xml");
            sc.setInitParameter("javax.faces.FACELETS_REFRESH_PERIOD", "1");
            sc.setInitParameter("javax.faces.FACELETS_SKIP_COMMENTS", Boolean.TRUE.toString());
            sc.setInitParameter("javax.faces.PARTIAL_STATE_SAVING_METHOD", Boolean.TRUE.toString());
            sc.setInitParameter("javax.faces.PROJECT_STAGE", "Development");
            sc.setInitParameter("javax.faces.STATE_SAVING_METHOD", "server");
            sc.setInitParameter("primefaces.CLIENT_SIDE_VALIDATION", Boolean.TRUE.toString());
            sc.setInitParameter("primefaces.FONT_AWESOME", Boolean.TRUE.toString());
            sc.setInitParameter("primefaces.THEME", "Omega");
        };
    }
