Class FileToMessagesJobFactoryBean<T>

java.lang.Object
  org.springframework.batch.integration.file.FileToMessagesJobFactoryBean<T>

All Implemented Interfaces:

org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.FactoryBean

public class FileToMessagesJobFactoryBean<T>
extends java.lang.Object
implements org.springframework.beans.factory.FactoryBean, org.springframework.beans.factory.BeanNameAware

A FactoryBean for a Job with a single step which just pumps messages from a file into a channel. The channel has to be a DirectChannel to ensure that failures propagate up to the step and fail the job execution. Normally this job will be used in conjunction with a JobLaunchingMessageHandler and a ResourcePayloadAsJobParameterStrategy, so that the user can just send a message to a request channel listing the files to be processed, and everything else just happens by magic. After a failure the job will be restarted just by sending it the same message.
