Class GuiceFilter

java.lang.Object

com.google.inject.servlet.GuiceFilter

All Implemented Interfaces:

javax.servlet.Filter

public class GuiceFilter
extends Object
implements javax.servlet.Filter

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 ServletModule.
