方法详细资料

• setAlwaysUseFullPath

  public void setAlwaysUseFullPath​(boolean alwaysUseFullPath)

  Whether URL lookups should always use the full path within the current web application context, i.e. within ServletContext.getContextPath().

  If set to false the path within the current servlet mapping is used instead if applicable (i.e. in the case of a prefix based Servlet mapping such as "/myServlet/*").

  By default this is set to "false".

• setUrlDecode

  public void setUrlDecode​(boolean urlDecode)

  Whether the context path and request URI should be decoded -- both of which are returned undecoded by the Servlet API, in contrast to the servlet path.

  Either the request encoding or the default Servlet spec encoding (ISO-8859-1) is used when set to "true".

  By default this is set to true.

  Note: Be aware the servlet path will not match when compared to encoded paths. Therefore use of urlDecode=false is not compatible with a prefix-based Servlet mapping and likewise implies also setting alwaysUseFullPath=true.

• isUrlDecode

  public boolean isUrlDecode()

  Whether to decode the request URI when determining the lookup path.

• setRemoveSemicolonContent

  public void setRemoveSemicolonContent​(boolean removeSemicolonContent)

  Set if ";" (semicolon) content should be stripped from the request URI.

  Default is "true".

• shouldRemoveSemicolonContent

  public boolean shouldRemoveSemicolonContent()

  Whether configured to remove ";" (semicolon) content from the request URI.

• setDefaultEncoding

  public void setDefaultEncoding​(String defaultEncoding)

  Set the default character encoding to use for URL decoding. Default is ISO-8859-1, according to the Servlet spec.

  If the request specifies a character encoding itself, the request encoding will override this setting. This also allows for generically overriding the character encoding in a filter that invokes the ServletRequest.setCharacterEncoding method.

  参数:

  defaultEncoding - the character encoding to use

• getDefaultEncoding

  protected String getDefaultEncoding()

  Return the default character encoding to use for URL decoding.

• getLookupPathForRequest

  public String getLookupPathForRequest​(HttpServletRequest request)

  Return the mapping lookup path for the given request, within the current servlet mapping if applicable, else within the web application.

  Detects include request URL if called within a RequestDispatcher include.

  参数:

  request - current HTTP request

  返回:

  the lookup path

  getPathWithinServletMapping(javax.servlet.http.HttpServletRequest), getPathWithinApplication(javax.servlet.http.HttpServletRequest)

• getPathWithinServletMapping

  public String getPathWithinServletMapping​(HttpServletRequest request)

  Return the path within the servlet mapping for the given request, i.e. the part of the request's URL beyond the part that called the servlet, or "" if the whole URL has been used to identify the servlet.

  Detects include request URL if called within a RequestDispatcher include.

  E.g.: servlet mapping="/*"; request URI="/test/a" -> "/test/a".

  E.g.: servlet mapping="/"; request URI="/test/a" -> "/test/a".

  E.g.: servlet mapping="/test/*"; request URI="/test/a" -> "/a".

  E.g.: servlet mapping="/test"; request URI="/test" -> "".

  E.g.: servlet mapping="/*.test"; request URI="/a.test" -> "".

  参数:

  request - current HTTP request

  返回:

  the path within the servlet mapping, or ""

• getPathWithinApplication

  public String getPathWithinApplication​(HttpServletRequest request)

  Return the path within the web application for the given request.

  Detects include request URL if called within a RequestDispatcher include.

  参数:

  request - current HTTP request

  返回:

  the path within the web application

  另请参阅:

  getLookupPathForRequest(javax.servlet.http.HttpServletRequest)

• getRequestUri

  public String getRequestUri​(HttpServletRequest request)

  Return the request URI for the given request, detecting an include request URL if called within a RequestDispatcher include.

  As the value returned by request.getRequestURI() is not decoded by the servlet container, this method will decode it.

  The URI that the web container resolves should be correct, but some containers like JBoss/Jetty incorrectly include ";" strings like ";jsessionid" in the URI. This method cuts off such incorrect appendices.

  参数:

  request - current HTTP request

  返回:

  the request URI

• getContextPath

  public String getContextPath​(HttpServletRequest request)

  Return the context path for the given request, detecting an include request URL if called within a RequestDispatcher include.

  As the value returned by request.getContextPath() is not decoded by the servlet container, this method will decode it.

  参数:

  request - current HTTP request

  返回:

  the context path

• getServletPath

  public String getServletPath​(HttpServletRequest request)

  Return the servlet path for the given request, regarding an include request URL if called within a RequestDispatcher include.

  As the value returned by request.getServletPath() is already decoded by the servlet container, this method will not attempt to decode it.

  参数:

  request - current HTTP request

  返回:

  the servlet path

• getOriginatingRequestUri

  public String getOriginatingRequestUri​(HttpServletRequest request)

  Return the request URI for the given request. If this is a forwarded request, correctly resolves to the request URI of the original request.

• getOriginatingContextPath

  public String getOriginatingContextPath​(HttpServletRequest request)

  Return the context path for the given request, detecting an include request URL if called within a RequestDispatcher include.

  As the value returned by request.getContextPath() is not decoded by the servlet container, this method will decode it.

  参数:

  request - current HTTP request

  返回:

  the context path

• getOriginatingServletPath

  public String getOriginatingServletPath​(HttpServletRequest request)

  Return the servlet path for the given request, detecting an include request URL if called within a RequestDispatcher include.

  参数:

  request - current HTTP request

  返回:

  the servlet path

• getOriginatingQueryString

  public String getOriginatingQueryString​(HttpServletRequest request)

  Return the query string part of the given request's URL. If this is a forwarded request, correctly resolves to the query string of the original request.

  参数:

  request - current HTTP request

  返回:

  the query string

• decodeRequestString

  public String decodeRequestString​(HttpServletRequest request,
                                    String source)

  Decode the given source string with a URLDecoder. The encoding will be taken from the request, falling back to the default "ISO-8859-1".

  The default implementation uses URLDecoder.decode(input, enc).

  参数:

  request - current HTTP request

  source - the String to decode

  返回:

  the decoded String

  另请参阅:

  WebUtils.DEFAULT_CHARACTER_ENCODING, ServletRequest.getCharacterEncoding(), URLDecoder.decode(String, String), URLDecoder.decode(String)

• determineEncoding

  protected String determineEncoding​(HttpServletRequest request)

  Determine the encoding for the given request. Can be overridden in subclasses.

  The default implementation checks the request encoding, falling back to the default encoding specified for this resolver.

  参数:

  request - current HTTP request

  返回:

  the encoding for the request (never null)

• removeSemicolonContent

  public String removeSemicolonContent​(String requestUri)

  Remove ";" (semicolon) content from the given request URI if the removeSemicolonContent property is set to "true". Note that "jsessionid" is always removed.

  参数:

  requestUri - the request URI string to remove ";" content from

  返回:

  the updated URI string

• decodePathVariables

  public Map<String,​String> decodePathVariables​(HttpServletRequest request,

  参数:

  request - current HTTP request

  vars - the URI variables extracted from the URL path

  返回:

  the same Map or a new Map instance

• decodeMatrixVariables
