All Implemented Interfaces:

Aware, BeanClassLoaderAware, InitializingBean

Direct Known Subclasses:

HessianServiceExporter, SimpleHessianServiceExporter

public class HessianExporter
extends RemoteExporter
implements InitializingBean

General stream-based protocol exporter for a Hessian endpoint.

Hessian is a slim, binary RPC protocol. For information on Hessian, see the Hessian website. Note: As of Spring 4.0, this exporter requires Hessian 4.0 or above.

Method Detail

setSerializerFactory

public void setSerializerFactory(SerializerFactory serializerFactory)

Specify the Hessian SerializerFactory to use.

This will typically be passed in as an inner bean definition of type com.caucho.hessian.io.SerializerFactory, with custom bean property values applied.

setSendCollectionType

public void setSendCollectionType(boolean sendCollectionType)

Set whether to send the Java collection type for each serialized collection. Default is "true".

setAllowNonSerializable

public void setAllowNonSerializable(boolean allowNonSerializable)

Set whether to allow non-serializable types as Hessian arguments and return values. Default is "true".

setRemoteResolver

public void setRemoteResolver(HessianRemoteResolver remoteResolver)

Specify a custom HessianRemoteResolver to use for resolving remote object references.

setDebug

public void setDebug(boolean debug)

Set whether Hessian's debug mode should be enabled, logging to this exporter's Commons Logging log. Default is "false".

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean

prepare

public void prepare()

Initialize this exporter.

invoke

public void invoke(java.io.InputStream inputStream,
                   java.io.OutputStream outputStream)
            throws java.lang.Throwable

Perform an invocation on the exported object.

Parameters:

inputStream - the request stream

outputStream - the response stream

Throws:

java.lang.Throwable - if invocation failed

doInvoke

protected void doInvoke(HessianSkeleton skeleton,
                        java.io.InputStream inputStream,
                        java.io.OutputStream outputStream)
                 throws java.lang.Throwable

Actually invoke the skeleton with the given streams.

Parameters:

skeleton - the skeleton to invoke

inputStream - the request stream

outputStream - the response stream

Throws:

java.lang.Throwable - if invocation failed
