Examples of org.apache.shiro.web.env.EnvironmentLoaderListener

org.apache.shiro.web.env.EnvironmentLoaderListener

Bootstrap listener to startup and shutdown the web application's Shiro {@link WebEnvironment} at ServletContext startup and shutdown respectively. This class exists only toimplement the {@link ServletContextListener} interface. All 'real' logic is done in the parent{@link EnvironmentLoader} class.

Usage

Define the following in {@code web.xml}:

 <listener> <listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class> </listener>

Configuration options, such as the {@code WebEnvironment} class to instantiate as well as Shiro configurationresource locations are specified as {@code ServletContext} {@code context-param}s and are documented in the {@link EnvironmentLoader} JavaDoc.

Shiro Filter

This listener is almost always defined in conjunction with the {@link org.apache.shiro.web.servlet.ShiroFilter ShiroFilter} to ensure security operations for web requests. Pleasesee the {@link org.apache.shiro.web.servlet.ShiroFilter ShiroFilter} JavaDoc for more. @see EnvironmentLoader @see org.apache.shiro.web.servlet.ShiroFilter ShiroFilter @since 1.2
