Question

我是vaadin 7的新手。我发现Spring Security Vaadin Integration存在一些问题。我正在使用JSP登录表单登录我的应用程序。我无法登录我的应用程序，我无法找到问题。

SpringApplicationServlet.java

    @Component
public class SpringApplicationServlet extends VaadinServlet {

    private WebApplicationContext applicationContext;
    private Class<? extends UI> applicationClass;
    private String applicationBean;
    private LocaleResolver localeResolver;

    @SuppressWarnings("unchecked")

                .getType(applicationBean);
        initLocaleResolver(applicationContext);
    }

    private void initLocaleResolver(ApplicationContext context) {
        try {
            this.localeResolver = (LocaleResolver) context.getBean(
                    DispatcherServlet.LOCALE_RESOLVER_BEAN_NAME,
                    LocaleResolver.class);
        } catch (NoSuchBeanDefinitionException ex) {
            this.localeResolver = new SessionLocaleResolver();
        }
    }

    protected void service(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        final Locale locale = localeResolver.resolveLocale(request);
        LocaleContextHolder.setLocale(locale);
        ServletRequestAttributes requestAttributes = new ServletRequestAttributes(
                request);
        RequestContextHolder.setRequestAttributes(requestAttributes);
        try {
            super.service(new HttpServletRequestWrapper(request) {
                @Override
                public Locale getLocale() {
                    return locale;
                }
            }, response);
        } finally {
            if (!locale.equals(LocaleContextHolder.getLocale())) {
                localeResolver.setLocale(request, response,
                        LocaleContextHolder.getLocale());
            }
            LocaleContextHolder.resetLocaleContext();
            RequestContextHolder.resetRequestAttributes();
        }
    }

    protected UI getNewApplication(HttpServletRequest request)
            throws ServletException {
        return (UI) applicationContext.getBean(applicationBean);
    }

    protected Class<? extends UI> getApplicationClass()
            throws ClassNotFoundException {
        return applicationClass;
    }

请帮我一些示例代码以使其正常工作。

问候

你没有写出你有什么错误。无论如何，我看到一个缺陷：servlet注册为： TestApp 但映射为：测试
