Мои классы Java являются ..

  1. Appconfig.java 

    @Configuration
@EnableWebMvc
@EnableAsync
@ComponentScan( basePackages = "com.wanclik" )
public class AppConfig extends WebMvcConfigurerAdapter {
    /**
     * Configure TilesConfigurer.
     */
    @Bean
    public TilesConfigurer tilesConfigurer(){
        TilesConfigurer tilesConfigurer = new TilesConfigurer();
        tilesConfigurer.setDefinitions(new String[] {"/WEB- 
    INF/pages/tiles/tiles.xml"});
        tilesConfigurer.setCheckRefresh(true);
        return tilesConfigurer;
    }

    /**
     * Configure ViewResolvers to deliver preferred views.
     */
    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        TilesViewResolver viewResolver = new TilesViewResolver();
        registry.viewResolver(viewResolver);
    }

    /**
     * Configure ResourceHandlers to serve static resources like CSS/ Javascript etc...
     */

    @Override

        registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    }

}

Из журналов видно, что класс org.slf4j.impl.StaticLoggerBinder не найден, поэтому убедитесь, что у вас есть зависимость в вашем pom.xml 

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.5.6</version>
</dependency>
