| <FONT color="green">033</FONT> * An {@code EnvironmentLoader} is responsible for loading a web application's Shiro {@link WebEnvironment}<a name="line.33"></a> |
| <FONT color="green">034</FONT> * (which includes the web app's {@link org.apache.shiro.web.mgt.WebSecurityManager WebSecurityManager}) into the<a name="line.34"></a> |
| <FONT color="green">035</FONT> * {@code ServletContext} at application startup.<a name="line.35"></a> |
| <FONT color="green">036</FONT> * <p/><a name="line.36"></a> |
| <FONT color="green">037</FONT> * In Shiro 1.1 and earlier, the Shiro ServletFilter was responsible for creating the {@code WebSecurityManager} and<a name="line.37"></a> |
| <FONT color="green">038</FONT> * any additional objects (security filters, etc). However, any component not filtered by the Shiro Filter (such<a name="line.38"></a> |
| <FONT color="green">039</FONT> * as other context listeners) was not able to easily acquire the these objects to perform security operations.<a name="line.39"></a> |
| <FONT color="green">040</FONT> * <p/><a name="line.40"></a> |
| <FONT color="green">041</FONT> * Due to this, in Shiro 1.2 and later, this {@code EnvironmentLoader} (or more likely, the<a name="line.41"></a> |
| <FONT color="green">042</FONT> * {@link EnvironmentLoaderListener} subclass) is the preferred mechanism to initialize<a name="line.42"></a> |
| <FONT color="green">043</FONT> * a Shiro environment. The Shiro Filter, while still required for request filtering, will not perform this<a name="line.43"></a> |
| <FONT color="green">044</FONT> * initialization at startup if the {@code EnvironmentLoader} (or listener) runs first.<a name="line.44"></a> |
| <FONT color="green">045</FONT> * <h2>Usage</h2><a name="line.45"></a> |
| <FONT color="green">046</FONT> * This implementation will look for two servlet context {@code context-param}s in {@code web.xml}:<a name="line.46"></a> |
| <FONT color="green">047</FONT> * {@code shiroEnvironmentClass} and {@code shiroConfigLocations} that customize how the {@code WebEnvironment} instance<a name="line.47"></a> |
| <FONT color="green">048</FONT> * will be initialized.<a name="line.48"></a> |
| <FONT color="green">049</FONT> * <h3>shiroEnvironmentClass</h3><a name="line.49"></a> |
| <FONT color="green">050</FONT> * The {@code shiroEnvironmentClass} {@code context-param}, if it exists, allows you to specify the<a name="line.50"></a> |
| <FONT color="green">051</FONT> * fully-qualified implementation class name of the {@link WebEnvironment} to instantiate. For example:<a name="line.51"></a> |
| <FONT color="green">052</FONT> * <pre><a name="line.52"></a> |
| <FONT color="green">053</FONT> * &lt;context-param&gt;<a name="line.53"></a> |
| <FONT color="green">054</FONT> * &lt;param-name&gt;shiroEnvironmentClass&lt;/param-name&gt;<a name="line.54"></a> |
| <FONT color="green">055</FONT> * &lt;param-value&gt;com.foo.bar.shiro.MyWebEnvironment&lt;/param-value&gt;<a name="line.55"></a> |
| <FONT color="green">056</FONT> * &lt;/context-param&gt;<a name="line.56"></a> |
| <FONT color="green">057</FONT> * </pre><a name="line.57"></a> |
| <FONT color="green">058</FONT> * If not specified, the default value is the {@link IniWebEnvironment} class, which assumes Shiro's default<a name="line.58"></a> |
| <FONT color="green">059</FONT> * <a href="http://shiro.apache.org/configuration.html">INI configuration format</a><a name="line.59"></a> |
| <FONT color="green">060</FONT> * <h3>shiroConfigLocations</h3><a name="line.60"></a> |
| <FONT color="green">061</FONT> * The {@code shiroConfigLocations} {@code context-param}, if it exists, allows you to specify the config location(s)<a name="line.61"></a> |
| <FONT color="green">062</FONT> * (resource path(s)) that will be relayed to the instantiated {@link WebEnvironment}. For example:<a name="line.62"></a> |
| <FONT color="green">063</FONT> * <pre><a name="line.63"></a> |
| <FONT color="green">064</FONT> * &lt;context-param&gt;<a name="line.64"></a> |

| <FONT color="green">067</FONT> * &lt;/context-param&gt;<a name="line.67"></a> |
| <FONT color="green">068</FONT> * </pre><a name="line.68"></a> |
| <FONT color="green">069</FONT> * The {@code WebEnvironment} implementation must implement the {@link ResourceConfigurable} interface if it is to<a name="line.69"></a> |
| <FONT color="green">070</FONT> * acquire the {@code shiroConfigLocations} value.<a name="line.70"></a> |
| <FONT color="green">071</FONT> * <p/><a name="line.71"></a> |
| <FONT color="green">072</FONT> * If this {@code context-param} is not specified, the {@code WebEnvironment} instance determines default resource<a name="line.72"></a> |
| <FONT color="green">073</FONT> * lookup behavior. For example, the {@link IniWebEnvironment} will check the following two locations for INI config<a name="line.73"></a> |
| <FONT color="green">074</FONT> * by default (in order):<a name="line.74"></a> |
| <FONT color="green">075</FONT> * <ol><a name="line.75"></a> |
| <FONT color="green">076</FONT> * <li>/WEB-INF/shiro.ini</li><a name="line.76"></a> |

| <FONT color="green">078</FONT> * </ol><a name="line.78"></a> |
| <FONT color="green">079</FONT> * <h2>Web Security Enforcement</h2><a name="line.79"></a> |
| <FONT color="green">080</FONT> * Using this loader will only initialize Shiro's environment in a web application - it will not filter web requests or<a name="line.80"></a> |
| <FONT color="green">081</FONT> * perform web-specific security operations. To do this, you must ensure that you have also configured the<a name="line.81"></a> |
