Introduction

In this example we will inject a OSGi service registry inside a Spring Context.

OSGi Service Registry

Let’s assume we got a Oracle datasource in our OSGi container with the following service description. (Please see this link)

<service interface="javax.sql.DataSource" ref="dataSource">
 <service-properties>
  <entry key="osgi.jndi.service.name" value="jdbc/oracleds"/>
  <entry key="datasource.name" value="OracleDS"/>
 </service-properties>
</service>

Spring Configuration

  1. Add the OSGi namespace in your Spring context.

    <beans xmlns=http://www.springframework.org/schema/beans" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:osgi=http://www.springframework.org/schema/osgi" 
xsi:schemaLocation="
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans.xsd 
http://www.springframework.org/schema/osgi 
http://www.springframework.org/schema/osgi/spring-osgi.xsd">

  2. Using the osgi:reference to get the datasource object. ```
