LOG_AND_SUPPRESS_ERROR_HANDLER

public static final org.springframework.util.ErrorHandler LOG_AND_SUPPRESS_ERROR_HANDLER

An ErrorHandler strategy that will log the Exception but perform no further handling. This will suppress the error so that subsequent executions of the task will not be prevented.

LOG_AND_PROPAGATE_ERROR_HANDLER

public static final org.springframework.util.ErrorHandler LOG_AND_PROPAGATE_ERROR_HANDLER

An ErrorHandler strategy that will log at error level and then re-throw the Exception. Note: this will typically prevent subsequent execution of a scheduled task.

decorateTaskWithErrorHandler

public static DelegatingErrorHandlingRunnable decorateTaskWithErrorHandler(Runnable task,
                                                                           @Nullable
                                                                           org.springframework.util.ErrorHandler errorHandler,
                                                                           boolean isRepeatingTask)

Decorate the task for error handling. If the provided ErrorHandler is not null, it will be used. Otherwise, repeating tasks will have errors suppressed by default whereas one-shot tasks will have errors propagated by default since those errors may be expected through the returned Future. In both cases, the errors will be logged.

getDefaultErrorHandler

public static org.springframework.util.ErrorHandler getDefaultErrorHandler(boolean isRepeatingTask)

Return the default ErrorHandler implementation based on the boolean value indicating whether the task will be repeating or not. For repeating tasks it will suppress errors, but for one-time tasks it will propagate. In both cases, the error will be logged.
