Method Detail

doPrepareConnection

protected void doPrepareConnection(HttpURLConnection con,
                                   int contentLength)
                            throws IOException

Provided so subclasses can perform additional configuration if required (eg set additional request headers for non-security related information etc).

Parameters:

con - the HTTP connection to prepare

contentLength - the length of the content to send

Throws:

IOException - if thrown by HttpURLConnection methods

prepareConnection

protected void prepareConnection(HttpURLConnection con,
                                 int contentLength)
                          throws IOException,
                                 AuthenticationCredentialsNotFoundException

Called every time a HTTP invocation is made.

Simply allows the parent to setup the connection, and then adds an Authorization HTTP header property that will be used for BASIC authentication.

The SecurityContextHolder is used to obtain the relevant principal and credentials.

Overrides:

prepareConnection in class SimpleHttpInvokerRequestExecutor

Parameters:

con - the HTTP connection to prepare

contentLength - the length of the content to send

Throws:

IOException - if thrown by HttpURLConnection methods

AuthenticationCredentialsNotFoundException - if the SecurityContextHolder does not contain a valid Authentication with both its principal and credentials not null
