Class HttpComponentsMessageSender

java.lang.Object
  org.springframework.ws.transport.http.AbstractHttpWebServiceMessageSender
      org.springframework.ws.transport.http.HttpComponentsMessageSender

All Implemented Interfaces:

DisposableBean, InitializingBean, WebServiceMessageSender

public class HttpComponentsMessageSender
extends AbstractHttpWebServiceMessageSender
implements InitializingBean, DisposableBean

WebServiceMessageSender implementation that uses Apache HttpClient to execute POST requests.

Allows to use a pre-configured HttpClient instance, potentially with authentication, HTTP connection pooling, etc. Authentication can also be set by injecting a Credentials instance (such as the UsernamePasswordCredentials).

Since:

2.1.0

Constructor Detail

HttpComponentsMessageSender

public HttpComponentsMessageSender()

Create a new instance of the HttpClientMessageSender with a default HttpClient that uses a default PoolingClientConnectionManager.

HttpComponentsMessageSender

public HttpComponentsMessageSender(org.apache.http.client.HttpClient httpClient)

Create a new instance of the HttpClientMessageSender with the given HttpClient instance.

This constructor does not change the given HttpClient in any way. As such, it does not set timeouts, nor does it add the HttpComponentsMessageSender.RemoveSoapHeadersInterceptor.

Parameters:

httpClient - the HttpClient instance to use for this sender

Method Detail

setCredentials

public void setCredentials(org.apache.http.auth.Credentials credentials)

Sets the credentials to be used. If not set, no authentication is done.

See Also:

UsernamePasswordCredentials, NTCredentials

getHttpClient

public org.apache.http.client.HttpClient getHttpClient()

Returns the HttpClient used by this message sender.

setHttpClient

public void setHttpClient(org.apache.http.client.HttpClient httpClient)

Set the HttpClient used by this message sender.

setConnectionTimeout

public void setConnectionTimeout(int timeout)

Sets the timeout until a connection is established. A value of 0 means never timeout.

Parameters:

timeout - the timeout value in milliseconds

See Also:

HttpConnectionParams.setConnectionTimeout(org.apache.http.params.HttpParams, int)

setReadTimeout

public void setReadTimeout(int timeout)

Set the socket read timeout for the underlying HttpClient. A value of 0 means never timeout.

Parameters:

timeout - the timeout value in milliseconds

See Also:

HttpConnectionParams.setSoTimeout(org.apache.http.params.HttpParams, int)

setMaxTotalConnections

public void setMaxTotalConnections(int maxTotalConnections)

Sets the maximum number of connections allowed for the underlying HttpClient.

Parameters:

maxTotalConnections - the maximum number of connections allowed

See Also:

PoolingClientConnectionManager.setMaxTotal(int)

setMaxConnectionsPerHost

public void setMaxConnectionsPerHost(Map<String,String> maxConnectionsPerHost)
                              throws URISyntaxException

Sets the maximum number of connections per host for the underlying HttpClient. The maximum number of connections per host can be set in a form accepted by the java.util.Properties class, like as follows:

 https://www.example.com=1
 http://www.example.com:8080=7
 http://www.springframework.org=10
 

The host can be specified as a URI (with scheme and port).

Parameters:

maxConnectionsPerHost - a properties object specifying the maximum number of connection

Throws:

URISyntaxException

See Also:

PoolingClientConnectionManager.setMaxPerRoute(HttpRoute, int)

setAuthScope

public void setAuthScope(org.apache.http.auth.AuthScope authScope)

Sets the authentication scope to be used. Only used when the credentials property has been set.

By default, the AuthScope.ANY is used.
