  • Method Details

    • setProxy

      public void setProxy(Proxy proxy)
      Set the Proxy to use for this request factory.

    • setBufferRequestBody

      public void setBufferRequestBody(boolean bufferRequestBody)
      Indicate whether this request factory should buffer the request body internally.

      Default is true. When sending large amounts of data via POST or PUT, it is recommended to change this property to false, so as not to run out of memory. This will result in a ClientHttpRequest that either streams directly to the underlying HttpURLConnection (if the Content-Length is known in advance), or that will use "Chunked transfer encoding" (if the Content-Length is not known in advance).

      See Also:

    • setChunkSize

      public void setChunkSize(int chunkSize)
      Set the number of bytes to write in each chunk when not buffering request bodies locally.

      Note that this parameter is only used when bufferRequestBody is set to false, and the Content-Length is not known in advance.

    • setConnectTimeout

      public void setConnectTimeout(int connectTimeout)
      Set the underlying URLConnection's connect timeout (in milliseconds). A timeout value of 0 specifies an infinite timeout.

      Default is the system's default timeout.

      See Also:

    • setReadTimeout

      public void setReadTimeout(int readTimeout)
      Set the underlying URLConnection's read timeout (in milliseconds). A timeout value of 0 specifies an infinite timeout.

      Default is the system's default timeout.

      See Also:

    • setOutputStreaming

      public void setOutputStreaming(boolean outputStreaming)
      Set if the underlying URLConnection can be set to 'output streaming' mode. Default is true.

      When output streaming is enabled, authentication and redirection cannot be handled automatically. If output streaming is disabled, the HttpURLConnection.setFixedLengthStreamingMode(int) and HttpURLConnection.setChunkedStreamingMode(int) methods of the underlying connection will never be called.

      Parameters:
      outputStreaming - if output streaming is enabled

    • createRequest

      public ClientHttpRequest createRequest(URI uri, HttpMethod httpMethod) throws IOException
      Description copied from interface: ClientHttpRequestFactory
      Create a new ClientHttpRequest for the specified URI and HTTP method.

      The returned request can be written to, and then executed by calling ClientHttpRequest.execute().

      Specified by:
      createRequest in interface ClientHttpRequestFactory
      Parameters:
      uri - the URI to create a request for
      httpMethod - the HTTP method to execute
      Returns:
      the created request
      Throws:
      IOException - in case of I/O errors

    • openConnection

      protected HttpURLConnection openConnection(URL url, @Nullable Proxy proxy) throws IOException
      Opens and returns a connection to the given URL.

      The default implementation uses the given proxy - if any - to open a connection.

      Parameters:
      url - the URL to open a connection to
      proxy - the proxy to use, may be null
      Returns:
      the opened connection
      Throws:
      IOException - in case of I/O errors

    • prepareConnection

      protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException
      Template method for preparing the given HttpURLConnection.

      The default implementation prepares the connection for input and output, and sets the HTTP method.

      Parameters:
      connection - the connection to prepare
      httpMethod - the HTTP request method (GET, POST, etc.)
      Throws:
      IOException - in case of I/O errors
