/**
|
||||
* Strategy for locating different resources on the file system. For each unique
|
||||
* step execution, the same file handle will be returned. A unique step is
|
||||
* defined as having the same job instance and step name. An external file mover
|
||||
* (such as an EAI solution) should rename and move any input files to conform
|
||||
* to the pattern defined here.<br/>
|
||||
*
|
||||
* If no pattern is passed in, then following default is used:
|
||||
*
|
||||
* <pre>
|
||||
* data/%JOB_NAME%/%STEP_NAME%.txt
|
||||
* </pre>
|
||||
*
|
||||
* The %% variables are replaced with the corresponding bean property at run
|
||||
* time, when the factory method is executed. To insert {@link JobParameters}
|
||||
* use a pattern with the parameter key surrounded by %%, e.g.
|
||||
*
|
||||
* <pre>
|
||||
* //home/jobs/data/%JOB_NAME%/%STEP_NAME%-%schedule.date%.txt
|
||||
* </pre>
|
||||
*
|
||||
* Note that the default pattern does not start with a separator. Because of the
|
||||
* implementation of the Spring Core Resource abstractions, it would need to
|
||||
* start with a double forward slash "//" to resolve to an absolute directory
|
||||
* (or else use a full URL with the file: prefix).<br/>
|
||||
*
|
||||
* To use this resource it must be initialised with a {@link StepExecution}.
|
||||
* The best way to do that is to register it as a listener in the step that is
|
||||
* going to need it. For this reason the resource implements
|
||||
* {@link StepExecutionListener}.
