我正在使用Vaadin（7.6.1）和SpringBoot（1.3.0），我在浏览器中遇到了有关应用程序URL的问题 .

如果我打电话给“http://localhost:8080/myApp/ " everything works fine -Spring Security blocks the request, redirects to login page, and after an authentication it calls the defaultSuccessUrl (" /＃！"). But if the user calls " http://localhost:8080/myApp " (without the last slash) Spring Security also works but redirects to the savedRequestUrl. In this case an error message (" failed to load the bootstrap javascript: ./vaadin/vaadinbootstrap.js ”，则会显示 .

通常我希望Spring Security重定向到savedRequestUrl，那么我该怎么办？ Servlet的URL模式是我的问题吗？在this answer中有一个基于注释的WebServlet的示例，但如果这是我的问题，我应该如何将它集成到我的应用程序中？

我定义了自己的SpringVaadinServlet，它覆盖了默认的vaadinServlet bean . 我的课程看起来像这样：

@SpringBootApplication
public class MyApp
{
    public static void main(String[] args)
    {
        SpringApplication.run(MyApp.class, args);
    }

    @Bean(name = "vaadinServlet")
    public CustomSpringVaadinServlet springVaadinServlet()
    {
        return new CustomSpringVaadinServlet();
    }
}

public class ServletInitializer extends SpringBootServletInitializer
{ 
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application)
    {
        [...]
        return application.sources(MyApp.class);
    }
}

public class CustomSpringVaadinServlet extends SpringVaadinServlet
{
    private static final long serialVersionUID = -6507628193889155490L;

    private final static Logger LOG = LoggerFactory.getLogger(SpringVaadinServletWsi.class);

    @Override
    protected void servletInitialized() throws ServletException
    {
        super.servletInitialized();

        getService().setSystemMessagesProvider(new SystemMessagesProvider()
        {
            private static final long serialVersionUID = -5253418651979378723L;

            @Override
            public SystemMessages getSystemMessages(SystemMessagesInfo systemMessagesInfo)
            {
                CustomizedSystemMessages messages = new CustomizedSystemMessages();
                messages.setCommunicationErrorCaption("Kommunikationsfehler");
                [...]
                return messages;
            }
        });
    }
}
