How to integrate Spring and Apache Jackrabbit? - spring

Can someone provide an example to integrate spring 3 and jackrabbit 2.5? If you please can provide spring configuration (applicationContext.xml) and also jackrabbit configuration (repository.xml) in example where oracle can be used as persistence manager.

Spring Boot with JDO

Do we have any support for JDO in Spring Boot Release Train? I couldn't find any recent relevant material.
I am looking for OSS options that can help in creating Spring Boot applications, portable to different sort of DB Engines (RDBMS to NoSQL or vice-versa), with minimal code change, assuming no change in DB model.
DataNucleus is an open source persistence provider fully compatible with JDO/JPA APIs. You can check how to integrate it with Spring Boot in sample code here.

Spring Boot 2.x Metrics classes

I have started using spring boot 2.0.0-Snapshot and I see that all Metric related classes and interfaces does not exists ?
Example:
The jar spring-boot-actuator-2.0.0.BUILD-SNAPSHOT.jar does not have package
org.springframework.boot.actuate.metrics.writer at all
Are they moved to somewhere else?
In Spring Boot 2 the previous metrics implementation has been replaced by integration with Micrometer. From the release notes:
Spring Boot’s own metrics have been replaced with support, including auto-configuration, for Micrometer and dimensional metrics. You can learn more about Micrometer in its user manual and Spring Boot’s reference guide
I can't find any guide for migrating from 1.x Spring Boot Metrics to 2.x Spring Boot Metrics but this change is quite recent so I suspect any such docs are a TODO. In the meantime, you could perhaps dig into the Pull Request or follow the Spring Boot 2 docs ...
Micrometer provides a separate module for each supported monitoring system. Depending on one (or more) of these modules is sufficient to get started with Micrometer in your Spring Boot application. To learn more about Micrometer’s capabilities, please refer to its reference documentation.

Apache Felix + Spring

I have successfully created an osgi application with apache felix. Now I want to integrate spring 4 with it. How do I do it ? Can anyone provide me a complete example ?
Thanks

In order to use Spring in your OSGi based java application for Spring Controllers or Dependency Injection you need to use Apache Aries Blueprint. Apache Karaf also provides a convenient distribution of the Felix OSGi Container with support for Apache Aries Blueprint. However before embarking on mixing Spring with OSGi I recommend reading the discussion on Blueprint here

Spring configuration using Java annotations

I have started working on an inventory management system (web application) using Spring Framework 3.1.1** and would like to configure Spring Framework using Java annotations. I searched Google, but I could not find a suitable example showing how to configure Spring Framework using Java annotations in a web application. Where is there a proper example or tutorial?
Spring Framework references are comprehensive. Refer to the Spring reference material, 3.11 Java-based container configuration.
Another option to consider is to use Java based configuration. It is more readable, and is easier than annotations.
