类 ScheduledExecutorFactoryBean

构造器详细资料

• ScheduledExecutorFactoryBean

  public ScheduledExecutorFactoryBean()

方法详细资料

• setPoolSize

  public void setPoolSize​(int poolSize)

  Set the ScheduledExecutorService's pool size. Default is 1.

• setScheduledExecutorTasks

  public void setScheduledExecutorTasks​(ScheduledExecutorTask... scheduledExecutorTasks)

  Register a list of ScheduledExecutorTask objects with the ScheduledExecutorService that this FactoryBean creates. Depending on each ScheduledExecutorTask's settings, it will be registered via one of ScheduledExecutorService's schedule methods.

  ScheduledExecutorService.schedule(java.lang.Runnable, long, java.util.concurrent.TimeUnit), ScheduledExecutorService.scheduleWithFixedDelay(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit), ScheduledExecutorService.scheduleAtFixedRate(java.lang.Runnable, long, long, java.util.concurrent.TimeUnit)

• setRemoveOnCancelPolicy

  public void setRemoveOnCancelPolicy​(boolean removeOnCancelPolicy)

  Set the remove-on-cancel mode on ScheduledThreadPoolExecutor (JDK 7+).

  Default is false. If set to true, the target executor will be switched into remove-on-cancel mode (if possible, with a soft fallback otherwise).

• setContinueScheduledExecutionAfterException

  public void setContinueScheduledExecutionAfterException​(boolean continueScheduledExecutionAfterException)

  Specify whether to continue the execution of a scheduled task after it threw an exception.

  Default is "false", matching the native behavior of a ScheduledExecutorService. Switch this flag to "true" for exception-proof execution of each task, continuing scheduled execution as in the case of successful execution.

• setExposeUnconfigurableExecutor

  public void setExposeUnconfigurableExecutor​(boolean exposeUnconfigurableExecutor)

  Specify whether this FactoryBean should expose an unconfigurable decorator for the created executor.

  Default is "false", exposing the raw executor as bean reference. Switch this flag to "true" to strictly prevent clients from modifying the executor's configuration.

• initializeExecutor

  @UsesJava7
  protected ExecutorService initializeExecutor​(ThreadFactory threadFactory,
                                               RejectedExecutionHandler rejectedExecutionHandler)

  从类复制的说明: ExecutorConfigurationSupport
  Create the target ExecutorService instance. Called by afterPropertiesSet.

  指定者:

  initializeExecutor 在类中 ExecutorConfigurationSupport

  参数:

  threadFactory - the ThreadFactory to use

  rejectedExecutionHandler - the RejectedExecutionHandler to use

  返回:

  a new ExecutorService instance

  另请参阅:

  ExecutorConfigurationSupport.afterPropertiesSet()

• createExecutor

  protected ScheduledExecutorService createExecutor​(int poolSize,
                                                    ThreadFactory threadFactory,
                                                    RejectedExecutionHandler rejectedExecutionHandler)

  Create a new ScheduledExecutorService instance.

  The default implementation creates a ScheduledThreadPoolExecutor. Can be overridden in subclasses to provide custom ScheduledExecutorService instances.

  参数:

  poolSize - the specified pool size

  threadFactory - the ThreadFactory to use

  rejectedExecutionHandler - the RejectedExecutionHandler to use

  返回:

  a new ScheduledExecutorService instance

  ExecutorConfigurationSupport.afterPropertiesSet(), ScheduledThreadPoolExecutor

• registerTasks

  protected void registerTasks​(ScheduledExecutorTask[] tasks,
                               ScheduledExecutorService executor)

  Register the specified ScheduledExecutorTasks on the given ScheduledExecutorService.

  参数:

  tasks - the specified ScheduledExecutorTasks (never empty)

  executor - the ScheduledExecutorService to register the tasks on.

• getRunnableToSchedule

  protected Runnable getRunnableToSchedule​(ScheduledExecutorTask task)

  Determine the actual Runnable to schedule for the given task.

  Wraps the task's Runnable in a DelegatingErrorHandlingRunnable that will catch and log the Exception. If necessary, it will suppress the Exception according to the "continueScheduledExecutionAfterException" flag.

  参数:

  task - the ScheduledExecutorTask to schedule

  返回:

  the actual Runnable to schedule (may be a decorator)

• getObject

  public ScheduledExecutorService getObject()

  从接口复制的说明: FactoryBean
  Return an instance (possibly shared or independent) of the object managed by this factory.

  As with a BeanFactory, this allows support for both the Singleton and Prototype design pattern.

  If this FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding FactoryBeanNotInitializedException.

  As of Spring 2.0, FactoryBeans are allowed to return null objects. The factory will consider this as normal value to be used; it will not throw a FactoryBeanNotInitializedException in this case anymore. FactoryBean implementations are encouraged to throw FactoryBeanNotInitializedException themselves now, as appropriate.

  指定者:

  getObject 在接口中 FactoryBean<ScheduledExecutorService>

  返回:

  an instance of the bean (can be null)

  FactoryBeanNotInitializedException

• getObjectType

  public Class<? extends ScheduledExecutorService> getObjectType()

  从接口复制的说明: FactoryBean
  Return the type of object that this FactoryBean creates, or null if not known in advance.

  This allows one to check for specific types of beans without instantiating objects, for example on autowiring.

  In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.

  This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.

  NOTE: Autowiring will simply ignore FactoryBeans that return null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

  指定者:

  getObjectType 在接口中 FactoryBean<ScheduledExecutorService>

  返回:

  the type of object that this FactoryBean creates, or null if not known at the time of the call

• isSingleton

  public boolean isSingleton()

  从接口复制的说明: FactoryBean
  Is the object managed by this factory a singleton? That is, will FactoryBean.getObject() always return the same object (a reference that can be cached)?

  NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from getObject() might get cached by the owning BeanFactory. Hence, do not return true unless the FactoryBean always exposes the same reference.

  The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.

  NOTE: This method returning false does not necessarily indicate that returned objects are independent instances. An implementation of the extended SmartFactoryBean interface may explicitly indicate independent instances through its SmartFactoryBean.isPrototype() method. Plain FactoryBean implementations which do not implement this extended interface are simply assumed to always return independent instances if the isSingleton() implementation returns false.

  指定者:

  isSingleton 在接口中 FactoryBean<ScheduledExecutorService>

  返回:

  whether the exposed object is a singleton
