所有已实现的接口:
WebRequestInterceptor
```
public class OpenPersistenceManagerInViewInterceptor
extends Object
implements WebRequestInterceptor
```
Spring web request interceptor that binds a JDO PersistenceManager to the thread for the entire processing of the request. Intended for the "Open PersistenceManager in View" pattern, i.e. to allow for lazy loading in web views despite the original transactions already being completed.
This interceptor makes JDO PersistenceManagers available via the current thread, which will be autodetected by transaction managers. It is suitable for service layer transactions via JdoTransactionManager or JtaTransactionManager as well as for non-transactional read-only execution.
In contrast to OpenPersistenceManagerInViewFilter, this interceptor is set up in a Spring application context and can thus take advantage of bean wiring.

`void`	`afterCompletion(WebRequest request, Exception ex)`	Callback after completion of request processing, that is, after rendering the view.

  - setPersistenceManagerFactory
```
public void setPersistenceManagerFactory(javax.jdo.PersistenceManagerFactory pmf)
```
    Set the JDO PersistenceManagerFactory that should be used to create PersistenceManagers.
  - getPersistenceManagerFactory
```
public javax.jdo.PersistenceManagerFactory getPersistenceManagerFactory()
```
    Return the JDO PersistenceManagerFactory that should be used to create PersistenceManagers.
  - preHandle
```
public void preHandle(WebRequest request)
               throws DataAccessException
```
    从接口复制的说明: WebRequestInterceptor
    Intercept the execution of a request handler before its invocation.
    Allows for preparing context resources (such as a Hibernate Session) and expose them as request attributes or as thread-local objects.
    指定者:
    preHandle 在接口中 WebRequestInterceptor
    参数:
    request - the current web request
    抛出:
    DataAccessException
  - postHandle
```
public void postHandle(WebRequest request,
                       ModelMap model)
```
    从接口复制的说明: WebRequestInterceptor
    Intercept the execution of a request handler after its successful invocation, right before view rendering (if any).
    Allows for modifying context resources after successful handler execution (for example, flushing a Hibernate Session).
    指定者:
    postHandle 在接口中 WebRequestInterceptor
    参数:
    request - the current web request
    model - the map of model objects that will be exposed to the view (may be null). Can be used to analyze the exposed model and/or to add further model attributes, if desired.
  - afterCompletion
```
public void afterCompletion(WebRequest request,
                            Exception ex)
                     throws DataAccessException
```
    从接口复制的说明: WebRequestInterceptor
    Callback after completion of request processing, that is, after rendering the view. Will be called on any outcome of handler execution, thus allows for proper resource cleanup.
    Note: Will only be called if this interceptor's preHandle method has successfully completed!
    指定者:
    afterCompletion 在接口中 WebRequestInterceptor
    参数:
    request - the current web request
    ex - exception thrown on handler execution, if any
    抛出:
    DataAccessException
  - getParticipateAttributeName
```
protected String getParticipateAttributeName()
```
    Return the name of the request attribute that identifies that a request is already filtered. Default implementation takes the toString representation of the PersistenceManagerFactory instance and appends ".FILTERED".
