afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

Specified by:

afterPropertiesSet in interface InitializingBean

createAsyncRequest

public AsyncClientHttpRequest createAsyncRequest(URI uri,
                                                 HttpMethod httpMethod)
                                          throws IOException

Description copied from interface: AsyncClientHttpRequestFactory

Create a new asynchronous AsyncClientHttpRequest for the specified URI and HTTP method.

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

Specified by:

createAsyncRequest in interface AsyncClientHttpRequestFactory

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

destroy

public void destroy()
             throws Exception

Description copied from class: HttpComponentsClientHttpRequestFactory

Shutdown hook that closes the underlying ClientConnectionManager's connection pool, if any.

Specified by:

destroy in interface DisposableBean

Overrides:

destroy in class HttpComponentsClientHttpRequestFactory

Throws:

Exception - in case of shutdown errors. Exceptions will get logged but not rethrown to allow other beans to release their resources as well.
