Spring Integration - JPA Sample
|
|
================================
|
|
|
|
# Overview
|
|
|
|
This sample illustrates how the JPA Components can be used. The example presented covers the following use cases
|
|
|
|
* List all people from the database
|
|
* Create a new Person record in the database
|
|
|
|
The first example demonstrates the use of an JPA Outbound gateway to retrieve a list of people. The second example uses an JPA Outbound Gateway in order to create a new Person record and then return the newly created Person record.
|
|
|
|
You have the option to choose between the following 3 persistence providers:
|
|
|
|
* [Hibernate](http://www.hibernate.org/)
|
|
* [OpenJPA](http://openjpa.apache.org/)
|
|
* [EclipseLink](http://www.eclipse.org/eclipselink/)
|
|
|
|
# Getting Started
|
|
|
|
Hibernate works out of the box and there are 2 options on how to execute the sample:
|
|
|
|
* running the "Main" class from within STS (Right-click on Main class --> Run As --> Java Application)
|
|
* or from the command line:
|
|
$ gradlew :jpa:run
|
|
|
|
For **OpenJPA** and **EclipseLink** to work, you must provide a [Java Agent](http://docs.oracle.com/javase/6/docs/api/java/lang/instrument/package-summary.html).
|
|
When using the Gradle Application Plugin, this is taken care of for you behind the scenes automatically. However,
|
|
when running the sample from within STS start the Main class with the following JVM flags:
|
|
|
|
-javaagent:/path/to/.m2/repository/org/springframework/spring-instrument/3.1.1.RELEASE/spring-instrument-3.1.1.RELEASE.jar
|
|
-javaagent:/path/to/.m2/repository/org/apache/openjpa/openjpa/2.2.0/openjpa-2.2.0.jar
|
|
|
|
With these flags you will be able to use all 3 persistence providers at once.
