Interface Summary

Interface	Description
ChunkListener	Listener interface for the lifecycle of a chunk.
ItemProcessListener<T,S>	Listener interface for the processing of an item.
ItemReadListener<T>	Listener interface around the reading of an item.
ItemWriteListener<S>	Listener interface for the writing of items.
Job	Batch domain object representing a job.
JobExecutionListener	Provide callbacks at specific points in the lifecycle of a Job.
JobKeyGenerator<T>	Strategy interface for the generation of the key used in identifying unique JobInstance.
JobParametersIncrementer	Interface for obtaining the next JobParameters in a sequence.
JobParametersValidator	Strategy interface for a Job to use in validating its parameters for an execution.
SkipListener<T,S>	Interface for listener to skipped items.
Step	Batch domain interface representing the configuration of a step.
StepExecutionListener	Listener interface for the lifecycle of a Step.
StepListener	Marker interface that acts as a parent to all step domain listeners, such as: StepExecutionListener, ChunkListener, ItemReadListener and ItemWriteListener

Class Summary

Class	Description
DefaultJobKeyGenerator	Default implementation of the JobKeyGenerator interface.
Entity	Batch Domain Entity class.
ExitStatus	Value object used to carry information about the status of a job or step execution.
JobExecution	Batch domain object representing the execution of a job.
JobInstance	Batch domain object representing a uniquely identifiable job run.
JobParameter	Domain representation of a parameter to a batch job.
JobParameters	Value object representing runtime parameters to a batch job.
JobParametersBuilder	Helper class for creating JobParameters.
StepContribution	Represents a contribution to a StepExecution, buffering changes until they can be applied at a chunk boundary.
StepExecution	Batch domain object representation the execution of a step.

Enum Summary

Enum	Description
BatchStatus	Enumeration representing the status of an Execution.
JobParameter.ParameterType	Enumeration representing the type of a JobParameter.

Exception Summary

Exception	Description
JobExecutionException	Root of exception hierarchy for checked exceptions in job and step execution.
JobInterruptedException	Exception to indicate the the job has been interrupted.
JobParametersInvalidException	Exception for Job to signal that some JobParameters are invalid.
StartLimitExceededException	Indicates the step's start limit has been exceeded.
UnexpectedJobExecutionException	Indicates to the framework that a critical error has occurred and processing should immediately stop.

Package org.springframework.batch.core Description

Core domain context for Spring Batch covering jobs, steps, configuration and execution abstractions. Most classes here are interfaces with implementations saved for specific applications. This is the public API of Spring Batch. There is a reference implementation of the core interfaces in the execution module.
