## org.springframework.web.portlet.handler
Class SimplePortletPostProcessor

    java.lang.Object
      org.springframework.web.portlet.handler.SimplePortletPostProcessor

All Implemented Interfaces:
  Aware, BeanPostProcessor, DestructionAwareBeanPostProcessor, PortletConfigAware, PortletContextAware

    public class SimplePortletPostProcessor

extends Object
implements DestructionAwareBeanPostProcessor, PortletContextAware, PortletConfigAware

Bean post-processor that applies initialization and destruction callbacks to beans that implement the Portlet interface.

After initialization of the bean instance, the Portlet `init` method will be called with a PortletConfig that contains the bean name of the Portlet and the PortletContext that it is running in.

Before destruction of the bean instance, the Portlet `destroy` will be called.

Note that this post-processor does not support Portlet initialization parameters. Bean instances that implement the Portlet interface are supposed to be configured like any other Spring bean, that is, through constructor arguments or bean properties.

For reuse of a Portlet implementation in a plain Portlet container and as a bean in a Spring context, consider deriving from Spring's GenericPortletBean base class that applies Portlet initialization parameters as bean properties, supporting both initialization styles.

Alternatively, consider wrapping a Portlet with Spring's PortletWrappingController. This is particularly appropriate for existing Portlet classes, allowing to specify Portlet initialization parameters etc.

  2.0

Constructor Detail

### SimplePortletPostProcessor

    public SimplePortletPostProcessor()

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`
  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

### postProcessBeforeInitialization

    public Object postProcessBeforeInitialization(Object bean,
                                                  String beanName)
                                           throws BeansException

  Description copied from interface: `BeanPostProcessor`
  Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's `afterPropertiesSet` or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

  Specified by:
    `postProcessBeforeInitialization` in interface `BeanPostProcessor`
  Parameters:
    `bean` - the new bean instance
    `beanName` - the name of the bean
  Returns:
    the bean instance to use, either the original or a wrapped one; if `null`, no subsequent BeanPostProcessors will be invoked
  Throws:
    `BeansException` - in case of errors
  See Also:
    `InitializingBean.afterPropertiesSet()`

### postProcessAfterInitialization

    public Object postProcessAfterInitialization(Object bean,
                                                 String beanName)
                                          throws BeansException

  Description copied from interface: `BeanPostProcessor`
  Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's `afterPropertiesSet` or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

  In case of a FactoryBean, this callback will be invoked for both the FactoryBean instance and the objects created by the FactoryBean (as of Spring 2.0). The post-processor can decide whether to apply to either the FactoryBean or created objects or both through corresponding `bean instanceof FactoryBean` checks.

  This callback will also be invoked after a short-circuiting triggered by a `InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class, java.lang.String)` method, in contrast to all other BeanPostProcessor callbacks.

  Specified by:
    `postProcessAfterInitialization` in interface `BeanPostProcessor`
  Parameters:
    `bean` - the new bean instance
    `beanName` - the name of the bean
  Returns:
    the bean instance to use, either the original or a wrapped one; if `null`, no subsequent BeanPostProcessors will be invoked
  Throws:
    `BeansException` - in case of errors
  See Also:
    `InitializingBean.afterPropertiesSet()`, `FactoryBean`

### postProcessBeforeDestruction

    public void postProcessBeforeDestruction(Object bean,
                                             String beanName)
                                      throws BeansException

  Description copied from interface: `DestructionAwareBeanPostProcessor`
  Apply this BeanPostProcessor to the given bean instance before its destruction. Can invoke custom destruction callbacks.

  Like DisposableBean's `destroy` and a custom destroy method, this callback just applies to singleton beans in the factory (including inner beans).

  Specified by:
    `postProcessBeforeDestruction` in interface `DestructionAwareBeanPostProcessor`
  Parameters:
    `bean` - the bean instance to be destroyed
    `beanName` - the name of the bean
  Throws:
    `BeansException` - in case of errors
  See Also:
    `DisposableBean`, `AbstractBeanDefinition.setDestroyMethodName(java.lang.String)`
