方法详细资料

• 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.

• getEncoding

  public String getEncoding()

  Return the configured encoding for requests and/or responses.

  从以下版本开始:

  4.3

• setForceEncoding

  public void setForceEncoding​(boolean forceEncoding)

  Set whether the configured encoding of 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.

  This is the equivalent to setting both setForceRequestEncoding(boolean) and setForceResponseEncoding(boolean).

• setForceRequestEncoding

  public void setForceRequestEncoding​(boolean forceRequestEncoding)

  Set whether the configured encoding of this filter is supposed to override existing request 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.

  从以下版本开始:

  4.3

• isForceRequestEncoding

  public boolean isForceRequestEncoding()

  Return whether the encoding should be forced on requests

  从以下版本开始:

  4.3

• setForceResponseEncoding

  public void setForceResponseEncoding​(boolean forceResponseEncoding)

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

  Default is "false", i.e. do not modify the encoding. Switch this to "true" to enforce the specified encoding for responses in any case.

  从以下版本开始:

  4.3

• isForceResponseEncoding

  public boolean isForceResponseEncoding()

  Return whether the encoding should be forced on responses.

• doFilterInternal

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

  从类复制的说明: OncePerRequestFilter
  Same contract as for doFilter, but guaranteed to be just invoked once per request within a single request thread. See OncePerRequestFilter.shouldNotFilterAsyncDispatch() for details.

  Provides HttpServletRequest and HttpServletResponse arguments instead of the default ServletRequest and ServletResponse ones.

  指定者:

  doFilterInternal 在类中 OncePerRequestFilter

  抛出:

  ServletException

  IOException
