4.8.3 Listener

The J2EE specification defines many listeners, such as javax.servlet.http.HttpSessionListener.

Most of these listeners are supported in Hasor. Configure them by registering through SPI. For example:

Example

public class MyHttpSessionListener implements HttpSessionListener {
    ...
}

public class StartModule implements WebModule {
    public void loadModule(WebApiBinder apiBinder) throws Throwable {
        ...
        apiBinder.bindSpiListener(HttpSessionListener.class, new MyHttpSessionListener());
        ...
    }
}

The J2EE listeners currently supported by Hasor include:

• javax.servlet.http.HttpSessionListener
• javax.servlet.ServletContextListener
• javax.servlet.ServletRequestListener
