Added RepositoryPopulator abstraction and implementations based on Spring OXM Unmarshallers as well as Jackson. This allows arbitrary repositories being populated with data pulled from XML / JSON, no matter what store they are actually backed. The populator will eventually populate the repositories held in a Repositories instance. It can be used like this:
Repositories repositories = new Repositories(applicationContext);
ResourceReader reader = new JacksonResourceReader();
ResourceReaderRepositoryPopulator populator = new ResourceReaderRepositoryPopulator(reader);
populator.setResourceLocation("classpath*:data.json");
populator.populate(repositories);
The ResourceReader defines what technology shall be used to read the data from the file into objects. The ResourceReaderRepositoryPopulator uses the reader and can either get a set of Resource instances configured or is able to lookup resources using a location string. The actual Repositories instance captures all CrudRepository instances contained inside an ApplicationContext.
The populators can also be used from within XML configuration though the repository namespace elements shown below:
<repository:jackson-populator location="classpath:org/springframework/data/repository/init/data.json" />
<repository:unmarshaller-populator location="classpath:org/springframework/data/repository/init/data.xml" unmarshaller-ref="unmarshaller" />
Updated reference documentation accordingly.
We have declared some Spring dependencies optional in the pom.xml file. I've changed the template.mf to declare the package dependencies of these artifacts as optional as well.
Added custom CDI extension to use repositories in a CDI environment. Base class picks up all Spring Data repository interfaces and allows working with qualifiers to bind beans to be created to qualifiers.
Introduced version range for Spring dependency of [3.0.6.RELEASE, 3.1.0.RC1]. This causes Maven to scan the metadata in the configured repositories to find the latest version up to Spring 3.1.0.RC1. For users having the Spring Milestone repo configured this will resolve against 3.1.0.RC1 then. All others will get the latest one from Maven Central which is 3.0.6. To let Bundlor still use 3.0.6 I've created a org.springframework.version.30 property and let template.mf use that.
Unfortunately the beta version numbers of Querydsl are not OSGi compatible so that we have to maintain the version number in template.mf manually. Updated version of APT Maven plugin to 1.0.1.
Extracted common functionality from project Hades to build a common infrastructure for generic repository implementations independent of the underlying persistence mechanism. Fixes DATACMNS-2, DATACMNS-3, DATACMNS-4, DATACMNS-5, DATACMNS-6, DATACMNS-8, DATACMNS-9.
