All Implemented Interfaces:

Controller, InitializingBean

public class HttpInvokerServiceExporter

extends RemoteInvocationBasedExporter

implements Controller, InitializingBean

Web controller that exports the specified service bean as HTTP invoker service endpoint, accessible via an HTTP invoker proxy.

Simply deserializes remote invocation objects and serializes remote invocation results. Uses Java serialization just like RMI, but provides the same ease of setup as Caucho's HTTP-based Hessian and Burlap protocols.

Method Detail

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

handleRequest

public ModelAndView handleRequest(HttpServletRequest request,
                                  HttpServletResponse response)
                           throws IOException,
                                  ClassNotFoundException

Read a remote invocation from the request and write a remote invocation result to the response.

Specified by:

handleRequest in interface Controller

Parameters:

request - current HTTP request

response - current HTTP response

Returns:

a ModelAndView to render, or null if handled directly

Throws:

IOException

ClassNotFoundException

readRemoteInvocation

protected RemoteInvocation readRemoteInvocation(HttpServletRequest request)
                                         throws IOException,

Read a RemoteInvocation from the given HTTP request.

Parameters:

request - current HTTP request

Returns:

the RemoteInvocation object

Throws:

IOException - if thrown by operations on the request

ClassNotFoundException - if thrown by deserialization

protected void writeRemoteInvocationResult(HttpServletResponse response,
                                           RemoteInvocationResult result)
                                    throws IOException
