Best practice in SpringBatch

Hi there,

I'm looking for best practice in SpringBatch like: things which are mandatory, itemReader/writer declare in the same class as job, or in a separate one..
Is there any resource on the subject? I think i may try to write some of these; I discover the subject so I need it, are people would be interested?

It seems that there's not much of it online, i'm suprised.

Edit: After reading here and there and trying myself on a sample project. I would start with these:

• Just One Job in your batch
• Log jobParameters values, startTime via (JobLoggerListener)
• Log at the end of Job (JobLoggerListener): endTime, Status of Job, ExitStatus.exitCode, and description (maybe the returnCode for the system).
• Implements a ChunkListener to see in your log the progressing of your treatment.
• Organize your listeners in differents package so you can specify appender log for example just jobListener without log all the other details. So in Production, you have a nice log with just minimum information.
• Implements an ExitCodeGenerator to return to your system a meaning code for your ops team.
• Don't use Hibernate if not necessary, prefer JdbcTemplate.
• Use a HSQLDB database for unit testing.

For books, I read the "The Definitive Guide to Spring Batch" from Michael Minella which is great to learn the framework.

I’ve been looking for the same, and also a way to pass job params to the job when run with maven

[Laurent Dumas]

what maven command are you running?

I think I have found it. Addin a run.arguments property to the command seems to do the trick:

mvn spring-boot:run -Drun.arguments="key1=value1, key2=value2"

I have edited the post with some best practice I think are good. If you have time, tell me about it.
I have intention to make a sample project on github, but.. just need time to do it outside of daily work :p

By the way, I found that Baeldung has a couple recent articles about it and they include a companion repository in GitHub with a sample application. Here is one of them.

I would start first with Spring Batch Samples (github.com/spring-projects/spring-...).
After that, I would consult Spring Batch Reference Documentation (docs.spring.io/spring-batch/docs/c...).
There is also official SpringDeveloper YT channel where videos about Spring Batch could be found (youtube.com/user/SpringSourceDev/v...). Hope it helps!

Hi,
Thanks for sharing these resources. It sure helps. I am glad that you take time to answer my post. In fact, I'm also looking for organizing source kind of stuff. Like in a video, spring tells it is more convenient to create a static class like "StepConfiguration" which has reader/writer declaration, it is more readable for your job configuration class.
And too often, code in video are made for a presentation purpose, so a lot of code is in the same class.
I am new in this subject so I try things maybe I will make a post about this to see what people think (like I hate xml configuration, I prefer the annotation way). Maybe some are really obvious for spring expert but I prefer keep an objective eye on it.
