MultipartResolver and AbstractAnnotationConfigDispatcherServletInitializer

I am having trouble using a CommonsMultipartResolver

bean in combination with an initializer that extends AbstractAnnotationConfigDispatcherServletInitializer

.

I've used CommonsMultipartResolver successfully in a previous project, but the initializer does WebApplicationInitializer

.

Intuitively, I did this in an initializer extending AbstractAnnotationConfigDispatcherServletInitializer

.

@Override
  protected Class<?>[] getRootConfigClasses() {
    return new Class<?>[]{
        MultipartUploadConfig.class
    };
  }

  @Override
  protected Class<?>[] getServletConfigClasses() {
    return new Class<?>[]{
        WebMvcConfig.class

    };
  }

      

        
        
        
      

    

I thought this would have the same effect as with this code in WebApplicationInitializer

(This is a working config).

@Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext dispatcherServlet = new AnnotationConfigWebApplicationContext();
        dispatcherServlet.register(WebMvcConfig.class);

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

        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(MultipartUploadConfig.class);

        servletContext.addListener(new ContextLoaderListener(rootContext));
    }

      

        
        
        
      

    

Using AbstractAnnotationConfigDispatcherServletInitializer

I am getting the following error:

Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided

      

        
        
        
      

    

So, does anyone know how to make the multipartResolver bean work with AbstractAnnotationConfigDispatcherServletInitializer

?

Other relevant information:

WebMvcConfig.java

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = ...)
public class WebMvcConfig extends WebMvcConfigurerAdapter {
  ...

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

}

      

        
        
        
      

    

MultipartUploadConfig.java

@Configuration
public class MultipartUploadConfig {

  @Bean
  public CommonsMultipartResolver multipartResolver() {
    CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
    multipartResolver.setMaxUploadSize(8192);
    multipartResolver.setDefaultEncoding("utf-8");
    return multipartResolver;
  }
}
