Spring Batch is a lightweight, comprehensive batch framework designed to enable the development of robust batch applications vital for the daily operations of enterprise systems. Spring Batch builds upon the productivity, POJO-based development approach, and general ease of use capabilities people have come to know from the Spring Framework, while making it easy for developers to access and leverage more advanced enterprise services when necessary.
If you are looking for a runtime container for your Batch applications, or need a management console to view current and historic executions, take a look at Spring Batch Admin. It is a set of services (Java, JSON, JMX) and an optional web UI that you can use to manage and monitor a Batch system.
Clone the git repository using the URL on the Github home page:
$ git clone git://github.com/SpringSource/spring-batch.git
$ cd spring-batch
Use Maven 2.2.* (might work with 3.0, but we don't test it), then on the command line:
$ mvn install
or, the first time (to download the stuff that isn't in the Maven Central repository):
$ mvn install -P bootstrap
In STS (or any Eclipse distro or other IDE with Maven support), import the module directories as existing projects. They should compile and the tests should run with no additional steps.
This is the quickest way to get started. It requires an internet connection for download, and access to a Maven repository (remote or local).
- Download STS version 2.5.* (or better) from the SpringSource website. STS is a free Eclipse bundle with many features useful for Spring developers.
- Go to
File->New->Spring Template Projectfrom the menu bar (in the Spring perspective). - The wizard has a drop down with a list of template projects. One of them is a "Simple Spring Batch Project". Select it and follow the wizard.
- A project is created with all dependencies and a simple input/output job configuration. It can be run using a unit test, or on the command line (see instructions in the pom.xml).
Read the main project website and the User Guide. Look at the source code and the Javadocs. For more detailed questions, use the forum. If you are new to Spring as well as to Spring Batch, look for information about Spring projects.
Here are some ways for you to get involved in the community:
- Get involved with the Spring community on the Spring Community Forums. Please help out on the forum by responding to questions and joining the debate.
- Create JIRA tickets for bugs and new features and comment and vote on the ones that you are interested in.
- Github is for social coding: if you want to write code, we encourage contributions through pull requests from forks of this repository. If you want to contribute code this way, please reference a JIRA ticket as well covering the specific issue you are addressing.
- Watch for upcoming articles on Spring by subscribing to springframework.org
Before we accept a non-trivial patch or pull request we will need you to sign the contributor's agreement. Signing the contributor's agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do. Active contributors might be asked to join the core team, and given the ability to merge pull requests.
A convenient way to get started quickly with Spring Batch is to run the samples which are packaged in the samples module. There is also a simple command line sample (or "archetype") which has a bare bones but complete implementation of a simpel job. The source code for the samples (and the other modules) is available either from the Zip assembly or from Git.
- Download the "no-dependencies" version of the distribution and unzip to create a directory
org.springframework.batch-<versionId>. - Get the m2eclipse plugin (installed in STS out of the box). If you can't or don't want to install this plugin, you can use the Maven Eclipse Plugin to create the classpath entries you need.
- Open Eclipse and create a workspace as for the non-Mavenized version.
- Import the samples and archetype projects from the samples sub-directory in the directory you just unpacked.
- The project should build cleanly without having to fix the dependencies. If it doesn't, make sure you are online, and maybe try building on the command line first to make sure all the dependencies are downloaded. See the build instructions if you run into difficulty.
(N.B. the "archetype" is not a real Maven archetype, just a template project that can be used as a starting point for a self-contained batch job. It is the same project that can be imported into STS using the Project Template wizard.)
-
Download the distribution as above.
-
Then run Maven in the spring-batch-samples directory, e.g.
$ cd spring-batch-samples $ mvn test ...
Similar instructions would apply to other IDEs.
- Download the "no-dependencies" package and unzip to create a directory
spring-batch-<versionId>. - Open Eclipse and make a workspace in the directory you just created.
- Import the
org.springframework.batch.samplesproject from the samples directory. - Find all the compile scope and non-optional runtime jar files listed in the core dependencies report and infrastructure dependencies, and import them into the project.
- Force the workspace to build (e.g. Project -> Clean...)
- Run the unit tests in your project under src/test/java. N.B. the FootbalJobFunctionTests takes quite a long time to run.
You can get a pretty good idea about how to set up a job by examining the unit tests in the org.springframework.batch.sample package (in src/main/java) and the configuration in src/main/resources/jobs.
To launch a job from the command line instead of a unit test use the CommandLineJobRunner.main() method (see Javadocs included in that class).
