提交 spring 形式时404错误

我在尝试在Spring中提交表单时遇到了一些问题 . 每次我尝试我都会收到404错误 . 这是我的控制器：

@Controller
@RequestMapping("/admin/news")
public class NewsController {

    @Autowired
    private NewsService newsService;

    @RequestMapping(value = "/create", method = RequestMethod.GET)
    public String createNews(Model model) {
        return "admin.news.create";
    }

    @RequestMapping(value = "/list", method = RequestMethod.GET)
    public ModelAndView listNews(Model model) {
        return listNews(1);
    }

    @RequestMapping(value = "/list/{pageIndex}", method = RequestMethod.GET)
    public ModelAndView listNewsPage(@PathVariable int pageIndex) {
        return listNews(pageIndex);
    }

    @RequestMapping(value = "/save", method = RequestMethod.POST)
    public String saveNews(@Valid NewsDto newsDto, BindingResult bindingResult, Model model) {
        if (!bindingResult.hasErrors()) {
            newsService.save(newsDto);
            model.addAttribute("created", true);
            model.addAttribute("news", newsDto);
        }

        return "admin.news.create";
    }

    private ModelAndView listNews(int pageIndex) {
        ModelAndView modelAndView = new ModelAndView("admin.news.list");

        Page page = newsService.findAll(pageIndex);
        modelAndView.addObject("page", page);

        return modelAndView;
    }

    @ModelAttribute("news")
    private NewsDto newsDtoModel() {
        return new NewsDto();
    }
}

这是表单（我正在使用Apache Tiles）：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="spring" %>

<div id="page-header">
    <h3>Create a news</h3>
</div>

<div id="page-content">
    <div class="panel">
        <div class="panel-heading">
            News creation form
        </div>

        <div class="panel-content">
            <spring:form method="post" commandName="news" action="save">
                <spring:input path="title" class="u-full-width" type="text" placeholder="Title of the news" required="true" />
                <spring:errors path="title" cssClass="validation-error" />

                <spring:textarea path="text" class="u-full-width" placeholder="News text" required="true" />
                <spring:errors path="text" cssClass="validation-error" />

                <input class="button-primary" type="submit" value="Submit" />
            </spring:form>
        </div>
    </div>
</div>

我已经阅读并尝试了我在SO中找到的与此错误相关的所有解决方案，但没有运气，我也在表单操作中尝试了所有可能的路由组合，但我总是得到404错误 . 这是 Headers ：

任何的想法？

EDIT 1: 我会在这里添加我的配置 .

ApplicationContext的：

@Configuration
@ComponentScan("com.davidmogar.alsa")
@PropertySource("classpath:application.properties")
@Import({WebMvcContext.class, PersistenceContext.class, SecurityContext.class})
public class ApplicationContext {

    private static final String MESSAGE_SOURCE_BASE_NAME = "i18n/messages";

    @Bean
    MessageSource messageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setBasename(MESSAGE_SOURCE_BASE_NAME);
        messageSource.setUseCodeAsDefaultMessage(true);

        return messageSource;
    }

    @Bean
    PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }
}

WebAppInitializer：

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    private static final String CHARACTER_ENCODING_FILTER_ENCODING = "UTF-8";

    private static final String DISPATCHER_SERVLET_MAPPING = "/";

    @Override
    protected WebApplicationContext createRootApplicationContext() {
        WebApplicationContext context = super.createRootApplicationContext();
//        ConfigurableEnvironment env = (ConfigurableEnvironment) context.getEnvironment();
//        env.setActiveProfiles();
        return context;
}

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

@Override
protected Class<?>[] getServletConfigClasses() {
    return null;
}

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

@Override
protected Filter[] getServletFilters() {
    DelegatingFilterProxy delegatingFilterProxy = new DelegatingFilterProxy();
    delegatingFilterProxy.setTargetBeanName("springSecurityFilterChain");

    CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
    characterEncodingFilter.setEncoding(CHARACTER_ENCODING_FILTER_ENCODING);
    characterEncodingFilter.setForceEncoding(true);
    OpenEntityManagerInViewFilter openEntityManagerInViewFilter = new OpenEntityManagerInViewFilter();
    HiddenHttpMethodFilter hiddenHttpMethodFilter = new HiddenHttpMethodFilter();

    return new Filter[]{delegatingFilterProxy, characterEncodingFilter, openEntityManagerInViewFilter,
            hiddenHttpMethodFilter};
}

}

EDIT 2:

以下是URL的映射：
