- All Implemented Interfaces: 
- Filter, BeanNameAware, DisposableBean, InitializingBean, ServletContextAware
- public class CharacterEncodingFilter 
- extends OncePerRequestFilter
Servlet 2.3/2.4 Filter that allows one to specify a character encoding for
 requests. This is useful because current browsers typically do not set a
 character encoding even if specified in the HTML page or form.
 
This filter can either apply its encoding if the request does not
 already specify an encoding, or enforce this filter's encoding in any case
 ("forceEncoding"="true"). In the latter case, the encoding will also be
 applied as default response encoding on Servlet 2.4+ containers (although
 this will usually be overridden by a full content type set in the view).

CharacterEncodingFilter
public CharacterEncodingFilter()
setEncoding
public void setEncoding(String encoding)
- Set the encoding to use for requests. This encoding will be passed into a
 ServletRequest.setCharacterEncoding(java.lang.String)call.Whether this encoding will override existing request encodings
 (and whether it will be applied as default response encoding as well)
 depends on the "forceEncoding"flag.
 
 
- 
 
setForceEncoding
public void setForceEncoding(boolean forceEncoding)
- Set whether the configured encodingof this filter
 is supposed to override existing request and response encodings.Default is "false", i.e. do not modify the encoding if
 ServletRequest.getCharacterEncoding()returns a non-null value. Switch this to "true" to enforce the specified
 encoding in any case, applying it as default response encoding as well.
 Note that the response encoding will only be set on Servlet 2.4+
 containers, since Servlet 2.3 did not provide a facility for setting
 a default response encoding.

doFilterInternal
protected void doFilterInternal(HttpServletRequest request,
                                HttpServletResponse response,
                                FilterChain filterChain)
                         throws ServletException,
                                IOException
- Description copied from class: OncePerRequestFilter
- Same contract as for doFilter, but guaranteed to be
 just invoked once per request. Provides HttpServletRequest and
 HttpServletResponse arguments instead of the default ServletRequest
 and ServletResponse ones.
