如何从 Vaadin/Spring 应用程序提供静态资源?
我有 Vaadin Web 应用程序与 spring security 集成进行身份验证。 Vaadin servlet 的配置非常简单:
<servlet>
<servlet-name>Vaadin Application Servlet</servlet-name>
<servlet-class>com.example.SpringApplicationServlet</servlet-class>
<init-param>
<param-name>applicationBean</param-name>
<param-value>mainApplication</param-value>
</init-param>
<init-param>
<param-name>widgetset</param-name>
<param-value>com.example.widgetset.CustomWidgetSet</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>Vaadin Application Servlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
servlet 初始化 Spring Context 并返回 Vaadin 应用程序。我还为此配置了安全性,并配置了一个自定义登录表单,如下所示:
<servlet>
<servlet-name>login</servlet-name>
<jsp-file>/jsp/login.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>login</servlet-name>
<url-pattern>/login</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>login_error</servlet-name>
<jsp-file>/jsp/loginError.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>login_error</servlet-name>
<url-pattern>/login_error</url-pattern>
</servlet-mapping>
登录表单使用外部 CSS 进行样式设置,并且还有一些图像。基本上图像位于 /jsp/img 中,样式表位于 /jsp/login.css 中。因此 WAR 结构如下所示:
- /jsp
- /META-INF
- /VAADIN
- /WEB-INF
图像和 css 均未加载,因为显然所有这些请求都映射到 vaadin servlet。如何定义一些 Vaadin servlet 不提供服务的静态资源目录?我尝试过 spring mvc:resources 但没有用。感谢您的帮助。
再见, 菲利普
我已经弄清楚了。尽管这只是一种解决方法。我已将 Vaadin 应用程序 Servlet 映射到 /app/* 之类的位置,而不是 /* (请记住,在这种情况下,您还必须将相同的 servlet 映射到 /VAADIN/*)。通过此配置,我可以从我的 web 应用程序访问 jsp 目录,并且一切正常。我已经删除了整个 Spring 资源配置,因为这不起作用。
因此,我仍然对这个解决方案不太满意,宁愿以其他方式配置我的资源目录,但客户很高兴:)。如果有人找到了正确的解决方案,我将不胜感激地阅读它。
I have Vaadin web application with spring security integration for authentication. The configuration of the Vaadin servlet is pretty simple:
<servlet>
<servlet-name>Vaadin Application Servlet</servlet-name>
<servlet-class>com.example.SpringApplicationServlet</servlet-class>
<init-param>
<param-name>applicationBean</param-name>
<param-value>mainApplication</param-value>
</init-param>
<init-param>
<param-name>widgetset</param-name>
<param-value>com.example.widgetset.CustomWidgetSet</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>Vaadin Application Servlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
The servlet initializes the Spring Context and returns the Vaadin application. I have also configured the security for that and have a custom login form configured like this:
<servlet>
<servlet-name>login</servlet-name>
<jsp-file>/jsp/login.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>login</servlet-name>
<url-pattern>/login</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>login_error</servlet-name>
<jsp-file>/jsp/loginError.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>login_error</servlet-name>
<url-pattern>/login_error</url-pattern>
</servlet-mapping>
The login form is styled with an external css and there are also some images. Basically the images are located in /jsp/img and the stylesheet in /jsp/login.css. So the WAR structure looks like:
- /jsp
- /META-INF
- /VAADIN
- /WEB-INF
Neither the images nor the css gets loaded, because obviously all those requests are mapped to the vaadin servlet. How can I define some static resources directory, which wouldn't be served by the Vaadin servlet? I have tried the spring mvc:resources but that didn't work. Thank you for your help.
Bye,
Filip
I have figured this out. Although it is rather a workaround. I have mapped the Vaadin Application Servlet to something like /app/* instead of to /* (Remember that in this case you also have to map the same servlet to /VAADIN/*). With this configuration I am able to access the jsp directory from my webapp and everything works fine. I have deleted the whole Spring Resources configuration, as this just didn't work.
So once more, I am still pretty not pretty comfortable with this solution and would rather have my RESOURCES dir configured other way, but the client is happy :). If anyone has got the right solution I would appreciate to read it.

使用 url 重写过滤器来获得对 url 映射的更多控制。
然后将 Vaadin 应用程序映射到 /vaadin 例如,并在 urlrewrite.xml 中配置 url 映射
编辑
其他选项是将静态文件放在 /VAADIN/ 目录中。
Use a url rewrite filter to get more contro on url mapping.
then map Vaadin application to /vaadin for example and configure url maping in urlrewrite.xml
EDIT
Other option is put static files in /VAADIN/ directory.
我已经想通了。尽管这只是一种解决方法。我已将 Vaadin 应用程序 Servlet 映射到 /app/* 之类的位置,而不是 /* (请记住,在这种情况下,您还必须将相同的 servlet 映射到 /VAADIN/*)。通过此配置,我可以从我的 web 应用程序访问 jsp 目录,并且一切正常。我已经删除了整个 Spring 资源配置,因为这不起作用。
所以再一次,我仍然对这个解决方案不太满意,宁愿以其他方式配置我的 RESOURCES 目录,但是 c

可能会迟到,但对于在使用 vaadin
/*
映射时仍然遇到提供静态内容的问题的人来说,我找到的解决方案是使用 apache 的默认 servletorg.apache.catalina.servlets.DefaultServlet< /code>,因此 web.xml 将具有类似以下内容:
因此,在上面的示例中,尽管
/*
处有 vaadin,但仍将提供/customer/*
部分作为DefaultServlet
的静态内容Might be late but for who is still having problems with serving static content while using vaadin
/*
mapping, the solution I found was using apache's default servletorg.apache.catalina.servlets.DefaultServlet
, so a web.xml will have something like:So in the example above, despite having vaadin at
/*
, the/customer/*
part will be served as static content by theDefaultServlet
