Answer 1

Ihr Hauptfehler ist hier:

@Override 
protected String[] getServletMappings() { 
    return new String[] { "/*" }; 
} 

werden sollten:

@Override 
protected String[] getServletMappings() { 
    return new String[] { "/" }; 
} 

Answer 2

In Ihrem ApplicationConfig hinzufügen:

@Override 
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { 
     configurer.enable(); 
    } 

ein nd ändern diese ViewResolver:

@Bean 
public ViewResolver viewResolver(){ 
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); 
    viewResolver.setViewClass(JstlView.class); 
    viewResolver.setPrefix("/WEB-INF/views/"); 
    viewResolver.setSuffix(".jsp"); 
    return viewResolver; 
} 

vom InternalResourceViewResolver:

@Bean 
    public InternalResourceViewResolver getInternalResourceViewResolver() { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix("/WEB-INF/views/"); 
     resolver.setSuffix(".jsp"); 
     return resolver; 
    }
