Support for Spring Data

Spring Data is a collection of projects intended to make it easier to develop Spring-powered applications that use new data access technologies such as non-relational databases. Based on a model of exposing Repository objects, Spring Data allows applications to access data in a simple and consistent way across many new platforms. Spring Batch 2.2.0.RC1 now provides ItemReader and ItemWriter implementations for a number of the data stores supported by Spring Data including MongoDB, Neo4j, and Gemfire (write only). In addition, Spring Batch 2.2.0.RC1 now has a RepositoryItemReader and RepositoryItemWriter that will read and write items from custom Spring Data Repository implementations.

Java Configuration

With this release, Spring Batch 2.2.0.RC1 now supports Java based job definitions. Building a job definition with java configuration is now available via the new @EnableBatchProcessing annotation and a collection of builders that allow you to construct jobs, steps, flows, splits, etc. By using the @EnableBatchProcessing annotation the following features are enabled:

• Creation of StepScope - Allowing the configuration of beans via @Scope("step")
• @Autowired - A JobRepository, JobLauncher, JobRegistry, PlatformTransactionManager, JobBuilderFactory and StepBuilderFactory are all available to be autowired into your context.

Non-identifying Job Parameters

Spring Batch 2.2.0.RC1 now supports the use of job parameters that do not contribute to the generation of a JobInstance's identity. As part of this update, the JobParameters is no longer associated with a JobInstance and is now associated with a JobExecution. To support this change, the job repository schema has updated and a migration script has been provided. You can read the details about the migration script in the Getting Started Guide.
