No bean named 'springSecurityFilterChain' is defined error with javaconfig

Question

I'm having some problems adding spring security. It shows an error that says:No bean named 'springSecurityFilterChain' is defined

public class WebInitializer implements WebApplicationInitializer {

    public void onStartup(ServletContext servletContext) throws ServletException {


        // Create the 'root' Spring application context
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(App.class);
        servletContext.addListener(new ContextLoaderListener(rootContext));


       // security filter
        servletContext.addFilter(
                "springSecurityFilterChain",
                new DelegatingFilterProxy("springSecurityFilterChain"))
                .addMappingForUrlPatterns(null, false, "/*");

        // Manage the lifecycle of the root application context
        AnnotationConfigWebApplicationContext webContext = new AnnotationConfigWebApplicationContext();
        webContext.register(WebConfig.class);
        webContext.setServletContext(servletContext);


        ServletRegistration.Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(webContext));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);
    }
}

In the moment I add the security filter, it shows this error. I've been like crazy trying to resolve this with no success.

This is my WebSecurityConfigurerAdapter

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().withUser("tom").password("123456").roles("USER");
        auth.inMemoryAuthentication().withUser("bill").password("123456").roles("ADMIN");
        auth.inMemoryAuthentication().withUser("james").password("123456").roles("SUPERADMIN");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.authorizeRequests()
                .antMatchers("/signin").access("hasRole('ROLE_ADMIN')")
                .and().formLogin();

    }
}

WebConfig

@Configuration
@EnableWebMvc
@ComponentScan(value = {"com.hp.visitor.controller"})
@Import({ WebSecurityConfig.class })
public class WebConfig extends WebMvcConfigurerAdapter {

    @Bean
    UrlBasedViewResolver setupViewResolver(){
        UrlBasedViewResolver resolver = new UrlBasedViewResolver();
        resolver.setPrefix("/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    }

}

I've been trying a lot, but it always shows an 503 error.

How can I fix it?

Try registering the security filter this way

FilterRegistration.Dynamic securityFilter = servletContext.addFilter("springSecurityFilterChain", DelegatingFilterProxy.class);
    securityFilter.addMappingForUrlPatterns(null, false, "/*");

And add the @Import({WebSecurityConfig.class}) in the configuration class you declare as your rootContext in WebInitializer in your case is in App.java
