类 ForwardedHeaderFilter

构造器详细资料

• ForwardedHeaderFilter

  public ForwardedHeaderFilter()

方法详细资料

• setRemoveOnly

  public void setRemoveOnly​(boolean removeOnly)

  Enables mode in which any "Forwarded" or "X-Forwarded-*" headers are removed only and the information in them ignored.

  参数:

  removeOnly - whether to discard and ignore forwarded headers

  从以下版本开始:

  4.3.9

• setRelativeRedirects

  public void setRelativeRedirects​(boolean relativeRedirects)

  Use this property to enable relative redirects as explained in RelativeRedirectFilter, and also using the same response wrapper as that filter does, or if both are configured, only one will wrap.

  By default, if this property is set to false, in which case calls to HttpServletResponse.sendRedirect(String) are overridden in order to turn relative into absolute URLs, also taking into account forwarded headers.

  参数:

  relativeRedirects - whether to use relative redirects

  从以下版本开始:

  4.3.10

• shouldNotFilter

  protected boolean shouldNotFilter​(HttpServletRequest request)
                             throws ServletException

  从类复制的说明: OncePerRequestFilter
  Can be overridden in subclasses for custom filtering control, returning true to avoid filtering of the given request.

  The default implementation always returns false.

  覆盖:

  shouldNotFilter 在类中 OncePerRequestFilter

  参数:

  request - current HTTP request

  返回:

  whether the given request should not be filtered

  抛出:

  ServletException - in case of errors

• shouldNotFilterAsyncDispatch

  protected boolean shouldNotFilterAsyncDispatch()

  从类复制的说明: OncePerRequestFilter
  The dispatcher type javax.servlet.DispatcherType.ASYNC introduced in Servlet 3.0 means a filter can be invoked in more than one thread over the course of a single request. Some filters only need to filter the initial thread (e.g. request wrapping) while others may need to be invoked at least once in each additional thread for example for setting up thread locals or to perform final processing at the very end.

  Note that although a filter can be mapped to handle specific dispatcher types via web.xml or in Java through the ServletContext, servlet containers may enforce different defaults with regards to dispatcher types. This flag enforces the design intent of the filter.

  The default return value is "true", which means the filter will not be invoked during subsequent async dispatches. If "false", the filter will be invoked during async dispatches with the same guarantees of being invoked only once during a request within a single thread.

  覆盖:

  shouldNotFilterAsyncDispatch 在类中 OncePerRequestFilter

• shouldNotFilterErrorDispatch

  protected boolean shouldNotFilterErrorDispatch()

  从类复制的说明: OncePerRequestFilter
  Whether to filter error dispatches such as when the servlet container processes and error mapped in web.xml. The default return value is "true", which means the filter will not be invoked in case of an error dispatch.

  覆盖:

  shouldNotFilterErrorDispatch 在类中 OncePerRequestFilter

• 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
