java.lang.Object org.springframework.remoting.support.RemoteExporter
public abstract class RemoteExporter
Abstract base class for classes that export a remote service. Provides "service" and "serviceInterface" bean properties.
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 have serializable arguments etc.

checkService()
Check whether the service reference has been set. |

Check whether a service reference has been set, and whether it matches the specified service. |
protected String |
getExporterName()
Return a short name for this exporter. |

public void setService(Object service)
public Object getService()
public void setServiceInterface(Class serviceInterface)
public Class getServiceInterface()
public void setRegisterTraceInterceptor(boolean registerTraceInterceptor)
getProxyForService
for creating the proxy to expose.
Default is "true". RemoteInvocationTraceInterceptor's most important value is that it logs exception stacktraces on the server, before propagating an exception to the client.
protected boolean isRegisterTraceInterceptor()
public void setBeanClassLoader(ClassLoader classLoader)
BeanClassLoaderAware
class loader
to
a bean instance.
Invoked after the population of normal bean properties but
before an initialization callback such as
InitializingBean's
InitializingBean.afterPropertiesSet()
method or a custom init-method.
setBeanClassLoader
in interface BeanClassLoaderAware
classLoader
- the owning class loader; may be null
in
which case a default ClassLoader
must be used, for example
the ClassLoader
obtained via
ClassUtils.getDefaultClassLoader()
protected void checkService() throws IllegalArgumentException
IllegalArgumentException
setService(java.lang.Object)
protected void checkServiceInterface() throws IllegalArgumentException
protected Object getProxyForService()
Used to export a proxy that does not expose any internals but just
a specific interface intended for remote access. Furthermore, a
RemoteInvocationTraceInterceptor
will be registered (by default).
setServiceInterface(java.lang.Class)
,
setRegisterTraceInterceptor(boolean)
,
RemoteInvocationTraceInterceptor
protected String getExporterName()
Default is the unqualified class name (without package). Can be overridden in subclasses.
