setApplicationContext(ApplicationContext applicationContext)
Setting an
ApplicationContext is optional: If set, registered
tasks will be activated in the ContextRefreshedEvent phase;
if not set, it will happen at afterSingletonsInstantiated() time. |

setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)
Making a
BeanFactory available is optional; if not set,
SchedulingConfigurer beans won't get autodetected and
a scheduler has to be explicitly configured. |
void |
setEmbeddedValueResolver(org.springframework.util.StringValueResolver resolver)
Set the StringValueResolver to use for resolving embedded definition values.
|
void |
setScheduler(Object scheduler)
Set the
TaskScheduler that will invoke
the scheduled methods, or a ScheduledExecutorService
to be wrapped as a TaskScheduler. |
public static final String DEFAULT_TASK_SCHEDULER_BEAN_NAME
TaskScheduler bean to pick up: "taskScheduler".
Note that the initial lookup happens by type; this is just the fallback in case of multiple scheduler beans found in the context.
