New Plugin Request

[johnrengelman]

I've started work on a Grails plugin for Spring Batch, I'm going to be incrementally adding functionality to it, so the first release will be very basic.

My grails.org username is: jengelman

Plugins:

grails-spring-batch

grails-spring-batch-admin

Hi John,

I will be interested in what you come up with. We've been using spring-batch with grails in an enterprise data app for a while now.

regards,
Michael

do you have a github repo? I would be interested in using/contributing.

Repos are at:

I have a very basic implementation in the core project that provides new Grails Artefacts types for Job, Step, and Tasklet. I thought about it some more last night and I'm going to change it up a bit. My goal is to be able to declare the following class:

class FooJob {

   def static stepOrder = ['process', 'report']

}

class FooProcessStep {

   def static tasklet = true

}

class FooReportStep {}

class FooProcessTasklet {}

and this will all get wired up inside of Spring Batch without any XML. I also plan to automatically detect things like Validators and Listeners using convention.

As for the Spring Batch Admin, I tried to add the spring batch admin project to my Grails project and exposes it's Spring MVC framework, but I couldn't get it to work properly. I could get the main page to display at my specified servletPath (/batch in this case), but none of the sub pages would get picked up (like /batch/jobs). I've never used Spring MVC by itself, so I'm sure it's just some knowledge I don't have. It appears that the GrailsServletDispatcher is handling my requests for the sub pages. If someone wants to look at that, that would be awesome. My thought is that the Spring Batch Admin plugin would provide the generic Spring Batch Admin pages tied to the dataSource bean defined by the Grails application…thus again, no configuration.

I also need to add scripts to the core plugin to add the spring batch tables….though I'm not sure how to get the tables dynamically added by GORM unless I create domain objects for them…which I guess is a possibility.

Peter -

I'm having problems publishing to Grails Central.

I receive the following when attempting to publish:

$grails publish-plugin

application.properties found, using $GRAILS_HOME of /Users/john/devtools/grails/grails-2.0.3

| Plugin packaged grails-spring-batch-0.1.zip

| Plugin packaged grails-spring-batch-0.1.zip

| POM generated: /Users/john/workspace/grails-spring-batch/target/pom.xml

Publishing to Grails Central

Publishing to http://grails.org/api/v1.0/publish/spring-batch/0.1

| Error Error executing script PublishPlugin: java.lang.RuntimeException: Server returned error deploying to Grails central repository: 302 (Use --stacktrace to see the full trace)

I think I saw a message about this before and it something wrong with the permission string for the user. Would you mind taking a look? Thanks!

I now realise we need to be clearer on what constitutes the plugin
name :) I added permissions for 'grails-spring-batch' as per the
request but the name is in fact 'spring-batch'. A touch confusing I
know, sorry.

Anyway, please try again and let us know if it works.
