接口概要 接口 说明 ChunkProcessor<I> Interface defined for processingChunks.ChunkProvider<T> Interface for providingChunks to be processed, used by theChunkOrientedTaskletKeyGenerator Interface for defining keys to uniquely identify items.类概要 类 说明 BatchRetryTemplate A special purpose retry template that deals specifically with multi-valued stateful retry.Chunk<W> Encapsulation of a list of items to be processed and possibly a list of failed items to be skipped.ChunkMonitor Manage the offset data between the last successful commit and updates made to an input chunk.ChunkMonitor.ChunkMonitorData ChunkOrientedTasklet<I> ATaskletimplementing variations on read-process-write item handling.DefaultItemFailureHandler Default implementation of theItemListenerSupportclass that writes all exceptions via commons logging.FaultTolerantChunkProcessor<I,O> FaultTolerant implementation of theChunkProcessorinterface, that allows for skipping or retry of items that cause exceptions during writing.FaultTolerantChunkProvider<I> FaultTolerant implementation of theChunkProcessorinterface, that allows for skipping or retry of items that cause exceptions during reading or processing.SimpleChunkProcessor<I,O> Simple implementation of theChunkProcessorinterface that handles basic item writing and processing.SimpleChunkProvider<I> Simple implementation of the ChunkProvider interface that does basic chunk providing from anItemReader.SimpleRetryExceptionHandler AnExceptionHandlerthat is aware of the retry context so that it can distinguish between a fatal exception and one that can be retried.SkipWrapper<T> Wrapper for an item and its exception if it failed processing.异常错误概要 异常错误 说明 ForceRollbackForWriteSkipException Fatal exception to be thrown when a rollback must be forced, typically after catching an exception that otherwise would not cause a rollback.SkipOverflowException
