    • checkNotModified

      public boolean checkNotModified(long lastModifiedTimestamp)
      从类复制的说明: RequestContext
      Check whether the requested resource has been modified given the supplied last-modified timestamp (as determined by the application).

      This will also transparently set the "Last-Modified" response header and HTTP status when applicable.

      Typical usage: 

      
 public String myHandleMethod(RequestContext request, Model model) {
   long lastModified = // application-specific calculation
   if (request.checkNotModified(lastModified)) {
     // shortcut exit - no further processing necessary
     return null;
   }
   // further request processing, actually building content
   model.addAttribute(...);
   return "myViewName";
 }

      This method works with conditional GET/HEAD requests, but also with conditional POST/PUT/DELETE requests.

      Note: you can use either this #checkNotModified(long) method; or RequestContext.checkNotModified(String). If you want enforce both a strong entity tag and a Last-Modified value, as recommended by the HTTP specification, then you should use RequestContext.checkNotModified(String, long).

      If the "If-Modified-Since" header is set but cannot be parsed to a date value, this method will ignore the header and proceed with setting the last-modified timestamp on the response.

      覆盖:
      checkNotModified 在类中 RequestContext
      参数:
      lastModifiedTimestamp - the last-modified timestamp in milliseconds that the application determined for the underlying resource
      返回:
      whether the request qualifies as not modified, allowing to abort request processing and relying on the response telling the client that the content has not been modified

    • checkNotModified

      public boolean checkNotModified(String etag)
      从类复制的说明: RequestContext
      Check whether the requested resource has been modified given the supplied ETag (entity tag), as determined by the application.

      This will also transparently set the "ETag" response header and HTTP status when applicable.

      Typical usage: 

      
 public String myHandleMethod(RequestContext request, Model model) {
   String eTag = // application-specific calculation
   if (request.checkNotModified(eTag)) {
     // shortcut exit - no further processing necessary
     return null;
   }
   // further request processing, actually building content
   model.addAttribute(...);
   return "myViewName";
 }

      Note: you can use either this #checkNotModified(String) method; or RequestContext.checkNotModified(long). If you want enforce both a strong entity tag and a Last-Modified value, as recommended by the HTTP specification, then you should use RequestContext.checkNotModified(String, long).

      覆盖:
      checkNotModified 在类中 RequestContext
      参数:
      etag - the entity tag that the application determined for the underlying resource. This parameter will be padded with quotes (") if necessary.
      返回:
      true if the request does not require further processing.

    • checkNotModified

      public boolean checkNotModified(@Nullable String etag, long lastModifiedTimestamp)
      从类复制的说明: RequestContext
      Check whether the requested resource has been modified given the supplied ETag (entity tag) and last-modified timestamp, as determined by the application.

      This will also transparently set the "ETag" and "Last-Modified" response headers, and HTTP status when applicable.

      Typical usage: 

      
 public String myHandleMethod(RequestContext request, Model model) {
   String eTag = // application-specific calculation
   long lastModified = // application-specific calculation
   if (request.checkNotModified(eTag, lastModified)) {
     // shortcut exit - no further processing necessary
     return null;
   }
   // further request processing, actually building content
   model.addAttribute(...);
   return "myViewName";
 }

      This method works with conditional GET/HEAD requests, but also with conditional POST/PUT/DELETE requests.

      Note: The HTTP specification recommends setting both ETag and Last-Modified values, but you can also use #checkNotModified(String) or RequestContext.checkNotModified(long).

      覆盖:
      checkNotModified 在类中 RequestContext
      参数:
      etag - the entity tag that the application determined for the underlying resource. This parameter will be padded with quotes (") if necessary.
      lastModifiedTimestamp - the last-modified timestamp in milliseconds that the application determined for the underlying resource
      返回:
      true if the request does not require further processing.

      public void reset()
      从类复制的说明: RequestContext
      Clears any data that exists in the buffer as well as the status code, headers. The state of calling RequestContext.getWriter() or RequestContext.getOutputStream() is also cleared. It is legal, for instance, to call RequestContext.getWriter(), reset() and then RequestContext.getOutputStream(). If RequestContext.getWriter() or RequestContext.getOutputStream() have been called before this method, then the corresponding returned Writer or OutputStream will be staled and the behavior of using the stale object is undefined. If the response has been committed, this method throws an IllegalStateException.
      覆盖:
      reset 在类中 RequestContext

    • sendRedirect

      public void sendRedirect(String location) throws IOException
      从类复制的说明: RequestContext
      Sends a temporary redirect response to the client using the specified redirect location URL and clears the buffer. The buffer will be replaced with the data set by this method. Calling this method sets the status code to 302 (Found). This method can accept relative URLs;the servlet container must convert the relative URL to an absolute URL before sending the response to the client. If the location is relative without a leading '/' the container interprets it as relative to the current request URI. If the location is relative with a leading '/' the container interprets it as relative to the servlet container root. If the location is relative with two leading '/' the container interprets it as a network-path reference (see RFC 3986: Uniform Resource Identifier (URI): Generic Syntax, section 4.2 "Relative Reference").

      If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.

      指定者:
      sendRedirect 在类中 RequestContext
      参数:
      location - the redirect location URL
      抛出:

      从类复制的说明: RequestContext
      Sends an error response to the client using the specified status code and clears the buffer. The server will preserve cookies and may clear or update any headers needed to serve the error page as a valid response. If an error-page declaration has been made for the web application corresponding to the status code passed in, it will be served back the error page

      If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.

      从类复制的说明: RequestContext

      Sends an error response to the client using the specified status and clears the buffer. The server defaults to creating the response to look like an HTML-formatted server error page containing the specified message, setting the content type to "text/html". The caller is not responsible for escaping or re-encoding the message to ensure it is safe with respect to the current response encoding and content type. This aspect of safety is the responsibility of the container, as it is generating the error page containing the message. The server will preserve cookies and may clear or update any headers needed to serve the error page as a valid response.

      If an error-page declaration has been made for the web application corresponding to the status code passed in, it will be served back in preference to the suggested msg parameter and the msg parameter will be ignored.

      If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.
