<div class="block">Primary Shiro Filter for web applications configuring Shiro via Servlet &lt;listener&gt; in web.xml.
<p/>
As of Shiro 1.2, this is Shiro's preferred filter for <code>web.xml</code> configuration. It expects the presence of a
Shiro <a href="../../../../../org/apache/shiro/web/env/WebEnvironment.html" title="interface in org.apache.shiro.web.env"><code>WebEnvironment</code></a> in the <code>ServletContext</code>, also
configured via <code>web.xml</code>.
<h2>Usage</h2>
As this Filter expects an available <a href="../../../../../org/apache/shiro/web/env/WebEnvironment.html" title="interface in org.apache.shiro.web.env"><code>WebEnvironment</code></a> instance to
be configured, it must be defined in <code>web.xml</code> with the companion
<a href="../../../../../org/apache/shiro/web/env/EnvironmentLoaderListener.html" title="class in org.apache.shiro.web.env"><code>EnvironmentLoaderListener</code></a>, which performs the necessary
environment setup. For example:
<pre>
&lt;listener&gt;
&lt;listener-class&gt;<a href="../../../../../org/apache/shiro/web/env/EnvironmentLoaderListener.html" title="class in org.apache.shiro.web.env"><code>EnvironmentLoaderListener</code></a>&lt;/listener-class&gt;
&lt;/listener&gt;
...
&lt;filter&gt;
&lt;filter-name&gt;ShiroFilter&lt;/filter-name&gt;
&lt;filter-class&gt;org.apache.shiro.web.servlet.ShiroFilter&lt;/filter-class&gt;
&lt;/filter&gt;
&lt;-- Filter all web requests. This filter mapping is typically declared
before all others to ensure any other filters are secured as well: --&gt;
&lt;filter-mapping&gt;
&lt;filter-name&gt;ShiroFilter&lt;/filter-name&gt;
&lt;url-pattern&gt;/*&lt;/url-pattern&gt;
&lt;/filter-mapping&gt;
</pre>
Configuration options (configuration file paths, etc) are specified as part of the
<code>EnvironmentLoaderListener</code> configuration. See the
<a href="../../../../../org/apache/shiro/web/env/EnvironmentLoader.html" title="class in org.apache.shiro.web.env"><code>EnvironmentLoader</code></a> JavaDoc for configuration options.</div>
