- org.springframework.context.support.ApplicationObjectSupport
- - org.springframework.web.portlet.context.PortletApplicationObjectSupport
  - - org.springframework.web.portlet.handler.PortletContentGenerator

所有已实现的接口:
Aware, ApplicationContextAware, PortletContextAware
直接已知子类:
AbstractController, AnnotationMethodHandlerAdapter
```
public abstract class PortletContentGenerator
extends PortletApplicationObjectSupport
```
Convenient superclass for any kind of web content generator, like AbstractController. Can also be used for custom handlers that have their own HandlerAdapter.
Supports portlet cache control options.
从以下版本开始:
2.0

  - PortletContentGenerator
```
public PortletContentGenerator()
```
- 方法详细资料
  - setRequireSession
```
public final void setRequireSession(boolean requireSession)
```
    Set whether a session should be required to handle requests.
  - isRequireSession
```
public final boolean isRequireSession()
```
    Return whether a session is required to handle requests.
  - setCacheSeconds
```
public final void setCacheSeconds(int seconds)
```
    Cache content for the given number of seconds. Default is -1, indicating no override of portlet content caching.
    Only if this is set to 0 (no cache) or a positive value (cache for this many seconds) will this class override the portlet settings.
    The cache setting can be overwritten by subclasses, before content is generated.
  - getCacheSeconds
```
public final int getCacheSeconds()
```
    Return the number of seconds that content is cached.
  - check
```
protected final void check(PortletRequest request,
                           PortletResponse response)
                    throws PortletException
```
    Check and prepare the given request and response according to the settings of this generator. Checks for a required session, and applies the number of cache seconds configured for this generator (if it is a render request/response).
    参数:
    request - current portlet request
    response - current portlet response
    抛出:
    PortletException - if the request cannot be handled because a check failed
  - checkAndPrepare
```
protected final void checkAndPrepare(PortletRequest request,
                                     MimeResponse response)
                              throws PortletException
```
    Check and prepare the given request and response according to the settings of this generator. Checks for a required session, and applies the number of cache seconds configured for this generator (if it is a render request/response).
    参数:
    request - current portlet request
    response - current portlet response
    抛出:
    PortletException - if the request cannot be handled because a check failed
  - checkAndPrepare
```
protected final void checkAndPrepare(PortletRequest request,
                                     MimeResponse response,
                                     int cacheSeconds)
                              throws PortletException
```
    Check and prepare the given request and response according to the settings of this generator. Checks for a required session, and applies the given number of cache seconds (if it is a render request/response).
    参数:
    request - current portlet request
    response - current portlet response
    cacheSeconds - positive number of seconds into the future that the response should be cacheable for, 0 to prevent caching
    抛出:
    PortletException - if the request cannot be handled because a check failed
  - preventCaching
```
protected final void preventCaching(MimeResponse response)
```
    Prevent the render response from being cached.
  - cacheForSeconds
```
protected final void cacheForSeconds(MimeResponse response,
                                     int seconds)
```
    Set portlet response to allow caching for the given number of seconds.
    参数:
    response - current portlet render response
    seconds - number of seconds into the future that the response should be cacheable for
  - applyCacheSeconds
```
protected final void applyCacheSeconds(MimeResponse response,
                                       int seconds)
```
    Apply the given cache seconds to the render response
    参数:
    response - current portlet render response
    seconds - positive number of seconds into the future that the response should be cacheable for, 0 to prevent caching
