Constructor Detail

SimpleClientHttpRequestFactory

public SimpleClientHttpRequestFactory()

Method Detail

setProxy

public void setProxy(java.net.Proxy proxy)

Sets the Proxy to use for this request factory.

setBufferRequestBody

public void setBufferRequestBody(boolean bufferRequestBody)

Indicates 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(int), HttpURLConnection.setFixedLengthStreamingMode(int)

setChunkSize

public void setChunkSize(int chunkSize)

Sets 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.

See Also:

setBufferRequestBody(boolean)

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:

URLConnection.setConnectTimeout(int)

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.

URLConnection.setReadTimeout(int)

createRequest

public ClientHttpRequest createRequest(java.net.URI uri,
                                       HttpMethod httpMethod)
                                throws java.io.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:

java.io.IOException - in case of I/O errors

openConnection

protected java.net.HttpURLConnection openConnection(java.net.URL url,
                                                    java.net.Proxy proxy)
                                             throws java.io.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:

java.io.IOException - in case of I/O errors

prepareConnection

protected void prepareConnection(java.net.HttpURLConnection connection,
                                 java.lang.String httpMethod)
                          throws java.io.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:

java.io.IOException - in case of I/O errors
