从XML到Java的Spring配置不起作用

我似乎无法让简单的Spring应用程序使用JavaConfig

public class WebApp extends AbstractAnnotationConfigDispatcherServletInitializer {

    private static final Logger logger = Logger.getLogger(WebApp.class);

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[0];
    }

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

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

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        logger.debug("onStartup");
        super.onStartup(servletContext);//MUST HAVE
        servletContext.setInitParameter("defaultHtmlEscape", "true");
    }

    @Configuration
    @EnableWebMvc
    @ComponentScan("com.doge.controller")
    public static class WebAppConfig extends WebMvcConfigurerAdapter {
    }
}

我总是在“localhost:8080/Build”和“localhost:8080”上得到404。

没有记录或打印任何内容，只有“信息：服务器在538毫秒内启动”。

初始化SpringWeb应用程序的选项很少。最简单的方法如下：

public class SpringAnnotationWebInitializer extends AbstractContextLoaderInitializer {

  @Override
  protected WebApplicationContext createRootApplicationContext() {
    AnnotationConfigWebApplicationContext applicationContext =
      new AnnotationConfigWebApplicationContext();
    applicationContext.register(WebAppConfig.class);
    return applicationContext;
  }

}

可在此处找到其他选项：

public class SpringAnnotationWebInitializer extends AbstractContextLoaderInitializer {

  @Override
  protected WebApplicationContext createRootApplicationContext() {
    AnnotationConfigWebApplicationContext applicationContext =
      new AnnotationConfigWebApplicationContext();
    applicationContext.register(WebAppConfig.class);
    return applicationContext;
  }

}
