Examples of TaskExecutorRepeatTemplate

org.springframework.batch.repeat.support.TaskExecutorRepeatTemplate
Provides {@link RepeatOperations} support including interceptors that can beused to modify or monitor the behaviour at run time.
This implementation is sufficient to be used to configure transactional behaviour for each item by making the {@link RepeatCallback} transactional,or for the whole batch by making the execute method transactional (but only then if the task executor is synchronous).
This class is thread-safe if its collaborators are thread-safe (interceptors, terminationPolicy, callback). Normally this will be the case, but clients need to be aware that if the task executor is asynchronous, then the other collaborators should be also. In particular the {@link RepeatCallback} thatis wrapped in the execute method must be thread-safe - often it is based on some form of data source, which itself should be both thread-safe and transactional (multiple threads could be accessing it at any given time, and each thread would have its own transaction).
