Class HessianServiceExporter

java.lang.Object
  org.springframework.remoting.support.RemoteExporter
      org.springframework.remoting.caucho.HessianServiceExporter

All Implemented Interfaces:

BeanClassLoaderAware, InitializingBean, HttpRequestHandler

public class HessianServiceExporter
extends RemoteExporter
implements HttpRequestHandler, InitializingBean

HTTP request handler that exports the specified service bean as Hessian service endpoint, accessible via a Hessian proxy.

Hessian is a slim, binary RPC protocol. For information on Hessian, see the Hessian website

This exporter will work with both Hessian 2.x and 3.x (respectively Resin 2.x and 3.x), autodetecting the corresponding skeleton class. As of Spring 2.0, it is also compatible with the new Hessian 2 protocol (a.k.a. Hessian 3.0.20+), while remaining compatible with older versions.

Note: Hessian services exported with this class can be accessed by any Hessian client, as there isn't any special handling involved.

Method Detail

setSerializerFactory

public void setSerializerFactory(com.caucho.hessian.io.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".

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 service exporter.

handleRequest

public void handleRequest(HttpServletRequest request,
                          HttpServletResponse response)
                   throws ServletException,
                          IOException

Processes the incoming Hessian request and creates a Hessian response.

Specified by:

handleRequest in interface HttpRequestHandler

Parameters:

request - current HTTP request

response - current HTTP response

Throws:

ServletException - in case of general errors

IOException - in case of I/O errors
