无法访问webapp下的views文件夹中的.xhtml文件。但如果我在webapp下面，我可以从webapp访问

标签： java spring-mvc spring-boot primefaces jsf-2.2

我无法访问webapp下的文件夹（视图）中的.xhtml，但如果我使用requestMapping URL将它们放在webapp下，我可以访问它。

有人可以使用 Spring MVC 和 spring boot 帮助我如何访问webapp下的文件夹中的 xhtml 文件，我＆＃39; m还计划通过在webapp下创建文件夹（css，images）来嵌入静态资源，如图像和css文件。

感谢。

这是我的代码

从FacesServlet的urlMappings中删除/views/*。在映射*.xhtml时，您不需要它，并且当servlet查找实际文件时，文件夹映射将从路径中删除。

@Bean
public ServletRegistrationBean facesServletRegistration() {
    ServletRegistrationBean registration = new ServletRegistrationBean(
            facesServlet(), "*.xhtml");
    registration.setName("FacesServlet");
    registration.addUrlMappings("*.xhtml", "/faces/*", "*.jsf");
    registration.setLoadOnStartup(1);
    registration.setEnabled(true);
    registration.setOrder(1);
    return registration;
}

事实上，你只能做*.xhtml映射，一切都会好的。

您现在可以使用http://yourserver/yourapp/views/home.xhtml访问您的文件。使用您当前的配置，此网址只会直接在home.xhtml目录下找到webapp。
