Class RemoteExporter

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

All Implemented Interfaces:

InitializingBean

Direct Known Subclasses:

BurlapServiceExporter, HessianServiceExporter, RmiServiceExporter

public abstract class RemoteExporter

extends java.lang.Object

implements InitializingBean

Abstract base class for classes that export a remote service. Provides a "serviceInterface" bean property.

Note that the service interface being used will show some signs of remotability, like the granularity of method calls that it offers. Furthermore, it has to require serializable arguments etc.

Method Detail

setServiceInterface

public void setServiceInterface(java.lang.Class serviceInterface)

Set the interface of the service to export. Typically optional: If not set, all implement interfaces will be exported. The interface must be suitable for the particular service and remoting tool.

getServiceInterface

protected java.lang.Class getServiceInterface()

Return the interface of the service to export.

setService

public void setService(java.lang.Object service)

Set the service to export. Typically populated via a bean reference.

getService

protected java.lang.Object getService()

Return the service to export.

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.Exception

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

Throws:

java.lang.Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails.

getProxyForService

protected java.lang.Object getProxyForService()

Get a proxy for the given service object, implementing the specified service interface.

Used to export a proxy that does not expose any internals but just a specific interface intended for remote access. Only applied if the remoting tool itself does not offer such means itself.

Returns:

the proxy
