Vaadin-SpringSecurityViewProvider

This add-on has the following goals:

• Integrate Spring Security into a Vaadin application
• Make Vaadin Views Spring managed prototype beans available through / for a navigator
• Simple description of views and no redundant @Component and @Scope on every view

Prerequisites

• A working Spring 3.2 setup including load-time-weaving and Spring Security for your application (See "Using @Configurable in Vaadin Components" for more information)
• A working setup of the "SpringVaadinIntegration Add-on"
• A Vaadin appliction protected by Spring Security with a non-Vaadin login page

Protecting your appliction

I recommend using the following setup of the SpringSecurityFilterChain, a dispatcher servlet and the SpringVaadinServlet like this in web.xml

    <servlet>
        <servlet-name>web</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>web</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <servlet>
        <servlet-name>application</servlet-name>
        <servlet-class>ru.xpoft.vaadin.SpringVaadinServlet</servlet-class>
        <init-param>
            <param-name>beanName</param-name>
            <param-value>application</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>application</servlet-name>
        <url-pattern>/app/*</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>application</servlet-name>
        <url-pattern>/VAADIN/*</url-pattern>
    </servlet-mapping>

Your login page can be a simple JSP page, a Spring JSTL view or whatever you like. It may not live under /app.

Examples and usage

Have a look at SpringSecurityViewProviderTest for an usage example and setting up basic security. There is also a blog post about the original idea.

In your UIs init method create a navigator and add the SpringSecurityViewProvider like this:

final ComponentContainerViewDisplay viewDisplay = new ComponentContainerViewDisplay(this.mainContent);
this.navigator = new Navigator(UI.getCurrent(), viewDisplay);
this.navigator.addProvider(SpringSecurityViewProvider.createViewProvider((Authentication) request.getUserPrincipal()));
