How to call many databases without hard-coding? - apache

Question

I have following scenario:
There are many sites/departments and every site has it's own ServiceMix and different number of databases. Those databases are grouped, for example there are two groups: production_one and production_two.
On every site I deployed bundles as a datasource, one datasource for every database.
Datasource: blueprint.xml
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://camel.apache.org/schema/blueprint/cxf"
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0"
xsi:schemaLocation="
http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">
<!-- Properties -->
<!-- blueprint property placeholders, that will use etc/datasources.cfg as the properties file -->
<cm:property-placeholder id="db.placeholder" persistent-id="datasources">
</cm:property-placeholder>
<!-- Datasource -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="url"
value="jdbc:sqlserver://${bundle_ds_1_db_host}:${bundle_ds_1_db_port};databaseName=${bundle_ds_1_db_database};" />
<property name="username" value="${bundle_ds_1_db_username}" />
<property name="password" value="${bundle_ds_1_db_password}" />
</bean>
<!-- Init database-->
<bean id="initDatabase"
class="com.xyz.mssql.ds.DatabaseInitBean"
init-method="create" destroy-method="destroy">
<property name="ds" ref="dataSource" />
</bean>
<service ref="dataSource" interface="javax.sql.DataSource">
<service-properties>
<entry key="datasource.name" value="${bundle_ds_1_ds_name}" />
<entry key="datasource.type" value="${bundle_ds_1_ds_type}" />
<entry key="datasource.id" value="${bundle_ds_1_ds_id}" />
<entry key="datasource.group_id" value="${bundle_ds_1_ds_group_id}" />
</service-properties>
</service>
There is also bundle, which receives a SOAP message via cxf and process it by calling database:
CXF: blueprint.xml
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://camel.apache.org/schema/blueprint/cxf"

<property name="ds" ref="dataSource" />
</bean>
<bean id="getDataProcessor"
class="com.xyz.mssql.soap1.GetDataProcessor">
<property name="ds" ref="dataSource" />
</bean>
<!-- DataSource -->
<reference id="dataSource" interface="javax.sql.DataSource"
filter="(datasource.name=mssql-ds-1)">
<reference-listener bind-method="onBind"
unbind-method="onUnbind">
<bean class="com.xyz.mssql.soap1.ListenerBean" />
</reference-listener>
</reference>
<!-- Camel Context -->
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route id="cxf">
<from uri="cxf:bean:processXEndpoint" />
<recipientList>
<simple>direct:${header.operationName}</simple>
</recipientList>
</route>
<route id="saveRoute">
<from uri="direct:saveData" />
<log message="Calling saveData" />
<process ref="saveDataProcessor" />
</route>
<route id="getRoute">
<from uri="direct:getData" />
<log message="Call getData" />
<process ref="getDataProcessor" />
</route>
</camelContext>
</blueprint>
The problem is, that following code inject to bean (ex: SaveDataProcessor) only one datasource resolved by it's name "datasource.name=mssql-ds-1", but I need to call many databases and on every servicemix installation there will be different number of them.
I need to call all databases (datasources) which have same type, for example "datasource.type=production_one".
Is it possible? How to do it?
How to pass to bean an array of datasources, or call this bean against every datasource which meet same conditions (name, type and so on).
