Hello world running in spring batch

This repository exist to show how to integrate spring-batch into your application without too much issues. It was a battle to make this work, I hope to help some of you by publishing a working example.

Databases

Mysql

• Running with mysql? add a -DENVIRONMENT=mysql to your JVM
• Adapt database credential in src/main/resources/META-INF/spring/batch/override/data-source-context.xml
• Ensure that src/main/resources/batch-mysql.properties exist in classpath

Oracle

• Running with oracle? add a -DENVIRONMENT=oracle to your JVM
• Adapt database credential in src/main/resources/META-INF/spring/batch/override/data-source-context.xml
• Override job-repository so isolation-level-for-create="READ_COMMITTED"
• Ensure that src/main/resources/batch-oracle.properties exist in classpath

Initializing datase

Ensure that at leas once in src/main/resources/batch-oracle.properties or src/main/resources/batch-mysql.properties the key batch.data.source.init=true or leave it always to false and run manually once the sql file schema-oracle10g.properties or schema-mysql.properties

Running spring batch ui not in context path root

so intead of https://localhost/dev/ you want to run spring batch admin ui in https://localhost/dev/batch

adapt web.xml

        <servlet-name>Batch Servlet</servlet-name>
        <url-pattern>/batch/*</url-pattern>
</servlet-mapping>

and uncomment in src/main/resources/META-INF/spring/batch/override/servlet-context.xml

Job

Should be located in classpath*:/META-INF/spring/jobs/*.xml one file per job is recommended

Scheduler

You can use Quartz but Spring > 3.0.2 offer a scheduler. Do not mix job and scheduler in the same file r you may have 2 instances of scheduler bean running at the same time in UI and in spring context, you can see the tricks in web.xml.
