Spring Boot Starter For A Single Step Job

This library serves as a starter for declaratively creating a single step Spring Batch Job. Using Spring Boot properties, you can configure a Spring Batch Job, with a single step using the supported Spring Batch functionality.

Current fuctionality includes the abilty to configure readers and writers via Spring Boot properties (yaml or properties). You can also provide your own ItemProcessor or Function implementation to serve as an ItemProcessor to be injected into the step being configured.

Getting Started

Create a new project from Spring Initializr with no dependencies and import it into your favorite IDE

Add this library to your pom.xml or build.gradle

<dependency>
	<groupId>org.springframework.batch</groupId>
	<artifactId>spring-boot-starter-singlestepjob</artifactId>
	<version>0.0.1-SNAPSHOT</version>
</dependency>

classpath 'org.springframework.batc:spring-boot-starter-singlestepjob:0.0.1-SNAPSHOT'

In your application.yml file, add the following to configure a job that takes an input CSV and reverses the order of the data.
```
spring:
  batch:
	job:
	  job-name: singleStepJob
	  step-name: singleStep
	  chunk-size: 10
	  filereader:
		resource : <PATH_TO_INPUT_CSV>
		name: inputReader
		names : <LIST_OF_NAMES_FOR_CSV_COLUMNS>
	  filewriter :
		resource : <PATH_TO_OUTPUT_CSV>
		name : outputWriter
		delimiter : ;
		names : <THE_REVERSE_OF_THE_NAMES_ABOVE>
```
Where the following values are set:
- PATH_TO_INPUT_CSV - The path to your input file
- LIST_OF_NAMES_FOR_CSV_COLUMNS - The list of names, one for each column in the CSV.
- PATH_TO_OUTPUT_CSV - The path to your output file
- THE_REVERSE_OF_THE_NAMES_ABOVE - The output will be generated via the order of the names you specify here.
Build your project via either ./mvnw clean package or ./gradlew clean build
Execute your job via java -jar my-jar.jar

All regular Spring Batch features apply so things like using an external database for the job repository can be accomplished via adding the appropriate JDBC driver, the Spring Boot JDBC driver, and the properties for the database connection.
