Examples of com.google.inject.servlet.GuiceFilter

com.google.inject.servlet.GuiceFilter
Apply this filter in web.xml above all other filters (typically), to all requests where you plan to use servlet scopes. This is also needed in order to dispatch requests to injectable filters and servlets:
```
 <filter> <filter-name>guiceFilter</filter-name> <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> </filter> <filter-mapping> <filter-name>guiceFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> 
```
This filter must appear before every filter that makes use of Guice injection or servlet scopes functionality. Typically, you will only register this filter in web.xml and register any other filters (and servlets) using a {@link ServletModule}. @author crazybob@google.com (Bob Lee) @author dhanji@gmail.com (Dhanji R.
