PortletWrappingController (Spring Framework API 2.0) - Spring Framework 2.0.5 API 文档英文版

The Spring Framework

Class PortletWrappingController

  extended by org.springframework.context.support.ApplicationObjectSupport
      extended by org.springframework.web.portlet.context.PortletApplicationObjectSupport
          extended by org.springframework.web.portlet.handler.PortletContentGenerator

All Implemented Interfaces:
BeanNameAware, DisposableBean, InitializingBean, ApplicationContextAware, PortletConfigAware, PortletContextAware, Controller

public class PortletWrappingController
extends AbstractController
implements BeanNameAware, InitializingBean, DisposableBean, PortletContextAware, PortletConfigAware

Controller implementation that wraps a portlet instance which it manages internally. Such a wrapped portlet is not known outside of this controller; its entire lifecycle is covered here.

Useful to invoke an existing portlet via Spring's dispatching infrastructure, for example to apply Spring HandlerInterceptors to its requests.

Example:

<bean id="wrappingController" class="org.springframework.web.portlet.mvc.PortletWrappingController">
   <property name="portletClass">
     <value>org.springframework.web.portlet.sample.HelloWorldPortlet</value>
   </property>
   <property name="portletName">
     <value>hello-world</value>
   </property>
   <property name="initParameters">
     <props>
       <prop key="config">/WEB-INF/hello-world-portlet-config.xml</prop>
     </props>
   </property>
 </bean>

Constructor Detail

PortletWrappingController

public PortletWrappingController()
Method Detail

setUseSharedPortletConfig

public void setUseSharedPortletConfig(boolean useSharedPortletConfig)
Set whether to use the shared PortletConfig object passed in through setPortletConfig, if available.

Default is "true". Turn this setting to "false" to pass in a mock PortletConfig object with the bean name as portlet name, holding the current PortletContext.

See Also:
setPortletConfig(javax.portlet.PortletConfig)

setPortletContext

public void setPortletContext(PortletContext portletContext)
Description copied from interface: PortletContextAware
Set the PortletContext that this object runs in.

Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext.

Specified by:
setPortletContext in interface PortletContextAware
Overrides:
setPortletContext in class PortletApplicationObjectSupport
Parameters:
portletContext - PortletContext object to be used by this object

setPortletConfig

public void setPortletConfig(PortletConfig portletConfig)
Description copied from interface: PortletConfigAware
Set the PortletConfigthat this object runs in.

Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext.

Specified by:
setPortletConfig in interface PortletConfigAware
Parameters:
portletConfig - PortletConfig object to be used by this object

setPortletClass

public void setPortletClass(Class portletClass)
Set the class of the Portlet to wrap. Needs to implement javax.portlet.Portlet.

See Also:
Portlet

setPortletName

public void setPortletName(String portletName)
Set the name of the Portlet to wrap. Default is the bean name of this controller.


setInitParameters

public void setInitParameters(Properties initParameters)
Specify init parameters for the portlet to wrap, as name-value pairs.


setBeanName

public void setBeanName(String name)
Description copied from interface: BeanNameAware
Set the name of the bean in the bean factory that created this bean.

Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:
setBeanName in interface BeanNameAware
Parameters:
name - the name of the bean in the factory. Note that this name is the actual bean name used in the factory, which may differ from the originally specified name: in particular for inner bean names, the actual bean name might have been made unique through appending "#..." suffixes. Use the BeanFactoryUtils.originalBeanName(String) method to extract the original bean name (without suffix), if desired.

afterPropertiesSet

public void afterPropertiesSet()
                        throws 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:
Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails.

handleActionRequestInternal

protected void handleActionRequestInternal(ActionRequest request,
                                           ActionResponse response)
                                    throws Exception
Description copied from class: AbstractController
Subclasses are meant to override this method if the controller is expected to handle action requests. The contract is the same as for handleActionRequest.

The default implementation throws a PortletException.

Overrides:
handleActionRequestInternal in class AbstractController
Throws:
Exception
See Also:
AbstractController.handleActionRequest(javax.portlet.ActionRequest, javax.portlet.ActionResponse), AbstractController.handleRenderRequestInternal(javax.portlet.RenderRequest, javax.portlet.RenderResponse)

handleRenderRequestInternal

protected ModelAndView handleRenderRequestInternal(RenderRequest request,
                                                   RenderResponse response)
                                            throws Exception
Description copied from class: AbstractController
Subclasses are meant to override this method if the controller is expected to handle render requests. The contract is the same as for handleRenderRequest.

The default implementation throws a PortletException.

Overrides:
handleRenderRequestInternal in class AbstractController
Throws:
Exception
See Also:
AbstractController.handleRenderRequest(javax.portlet.RenderRequest, javax.portlet.RenderResponse), AbstractController.handleActionRequestInternal(javax.portlet.ActionRequest, javax.portlet.ActionResponse)

destroy

public void destroy()
Description copied from interface: DisposableBean
Invoked by a BeanFactory on destruction of a singleton.

Specified by:
destroy in interface DisposableBean
