org.springframework.web.filter .CharacterEncodingFilter

CharacterEncodingFilter
public class CharacterEncodingFilter extends OncePerRequestFilter (Code)
	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). author: Juergen Hoeller since: 15.03.2004 See Also: CharacterEncodingFilter.setEncoding See Also: CharacterEncodingFilter.setForceEncoding See Also: javax.servlet.http.HttpServletRequest.setCharacterEncoding See Also: javax.servlet.http.HttpServletResponse.setCharacterEncoding

Method Summary
protected void	doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
public void	setEncoding(String encoding) Set the encoding to use for requests.
public void	setForceEncoding(boolean forceEncoding) Set whether the configured CharacterEncodingFilter.setEncoding encoding of this filter is supposed to override existing request and response encodings. Default is "false", i.e.

Method Detail

doFilterInternal
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException(Code)

setEncoding
public void setEncoding(String encoding)(Code)
	Set the encoding to use for requests. This encoding will be passed into a javax.servlet.http.HttpServletRequest.setCharacterEncoding call. Whether this encoding will override existing request encodings (and whether it will be applied as default response encoding as well) depends on the CharacterEncodingFilter.setForceEncoding "forceEncoding" flag.

setForceEncoding

public void setForceEncoding(boolean forceEncoding)(Code)

Set whether the configured CharacterEncodingFilter.setEncoding encoding of this filter is supposed to override existing request and response encodings.

Default is "false", i.e. do not modify the encoding if javax.servlet.http.HttpServletRequest.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.
