Loading multiple external properties files from spring

I want to load all the properties files with Spring from an external folder. I successfully load one file but adding a wildcard to the mix does not seem to work.
This works (load test.properties):
<bean id="propertiesLocation"
class="org.springframework.web.context.support.ServletContextParameterFactoryBean">
<property name="initParamName"><value>file://EXTERNAL_DIRECTORY/test.properties</value></property>
</bean>
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" ref="propertiesLocation"></property>
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="order" value="0"/>
</bean>
This does not (load *.properties):
<bean id="propertiesLocation"
class="org.springframework.web.context.support.ServletContextParameterFactoryBean">
<property name="initParamName"><value>file://EXTERNAL_DIRECTORY/*.properties</value></property>
</bean>
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" ref="propertiesLocation"></property>
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="order" value="0"/>
</bean>
The error:
Caused by: java.io.FileNotFoundException: /EXTERNAL_DIRECTORY/*.properties (No es un directorio)
How can I make Spring load all the external properties files in a folder?
Edit: I use the first bean (ServletContextParameterFactoryBean) because in the project I retrieve the path from the web.xml file. I forgot about this and just pasted the path in the bean, it is incorrect but has nothing to do with the question.

Try use following:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations" value="file://EXTERNAL_DIRECTORY/*.properties"/>
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="order" value="0"/>
</bean>
If you need include more resources you can do next:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations" >
<list>
<value>classpath:single.properties"</value>
<value>file://EXTERNAL_DIRECTORY/*.properties"</value>
<value>file://ANOTHER_EXTERNAL_DIRECTORY/*.properties"</value>
</list>
</property>
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="order" value="0"/>
</bean>
With default implementation of PropertyEditor, Spring will convert strings into Resource. You can find details in documentation.
Hope this will be helpful.

Apache Camel - Read JDBC dataSource properties from file

i'm using Apache Camel and i try to load datasource properties from this file
config.properties:
url = my_url
user = user_name
password = user_pass
this is dataSource (blueprint.xml):
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="my_url"/>
<property name="user" value="user_name"/>
<property name="password" value="user_pass"/>
</bean>
How can i read values from config.properties and insert them into dataSource properties ?

You talk about blueprint.xml, and camel, so I assume you are in an osgi container like Karaf/ServiceMix, and you are using Aries Blueprint.
Then you can use the cm namespace and a property-placeholder. If you use camel and want your properties to be dynamically reloaded, then you can use too an update strategy reload, which start/stop the blueprint container when the configuration change. This will load the configuration with pid "datasource" (ie, in karaf, the file etc/datasource.cfg) :
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.2.0"
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.2.0">
<cm:cm-properties id="myProps" persistent-id="datasource" update-strategy="reload"/>
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="${url}"/>
<property name="user" value="${user}"/>
<property name="password" value="${password}"/>
</bean>
</blueprint>
If you want to use your configuration file without using ConfigurationAdmin or dynamically reload your bundle, then you can use the ext namespace :
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.2.0">
<ext:property-placeholder>
<ext:location>file:config.properties</ext:location>
</ext:property-placeholder>
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="${url}"/>
<property name="user" value="${user}"/>
<property name="password" value="${password}"/>
</bean>
</blueprint>

According to code I assume you use probably spring as container. General solution in spring is to use PropertyPlaceHolder, your configuration will look like this:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>config.properties</value>
</property>
</bean>
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="${jdbc.myUrl}"/>
<property name="user" value="${jdbc.user_name}"/>
<property name="password" value="${jdbc.user_pass}"/>
</bean>
Please check the example for details.

Reading Dual/Multiple Properties in Spring

I'm trying to read the application specific properties from database, and I'm trying to keep the database credentials in properties file.
So I need to load both properties (File and DB), while the application is
loading.
I'm having my configuration as follows.
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="WEB-INF/config/db.properties"/>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<property name="properties">
<bean class="org.apache.commons.configuration.ConfigurationConverter" factory-method="getProperties">
<constructor-arg>
<bean class="org.apache.commons.configuration.DatabaseConfiguration">
<constructor-arg type="javax.sql.DataSource" ref="postgresqlDataSource"/>
<constructor-arg value="TBL_APP_SETTINGS"/>
<constructor-arg value="PROP_KEY"/>
<constructor-arg value="PROP_VALUE"/>
</bean>
</constructor-arg>
</bean>
</property>
</bean>
<bean id="postgresqlDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="url" value="${db.url}"/>
<property name="driverClassName" value="org.postgresql.Driver"/>
<property name="username" value="${db.user}"/>
<property name="password" value="${db.pass}"/>
<property name="initialSize" value="1"/>
<property name="maxActive" value="5"/>
<property name="validationQuery" value="SELECT 1"/>
<property name="timeBetweenEvictionRunsMillis" value="5000"/>
<property name="removeAbandonedTimeout" value="60"/>
<property name="minEvictableIdleTimeMillis" value="30000"/>
<property name="minIdle" value="3"/>
</bean>
It's throwing error for ${db.url}
please help how to do this? thanks in advance.

The easiest way is to externalize some of your config properties the guide is on spring.io site. You can pass properies as java system properties or command line arguments
The second way is to write your own PropertyPlaceholderConfigurer which will read properties from application.yml and from the database

I believe the easiest way you can do it is writing credentials into the spring xml and import it to your main xml and reference them as beans:
<bean id="dbUrl" class="java.lang.String">
<constructor-arg type="java.lang.String" value="jdbc://..."/>
</bean>
... same for dbUser and dbPassword
And then refer to the value using ref.

JBoss 7 Override JNDI Datasource

I have a Spring Web Application with Maven 3 and Datasources/Beans configured for local development on a h2 Database. For Testing there exists a JBoss AS 7.1 Server.
Is it possible to override a Bean / DataSource in a special JBoss XML-File, so that for local (IDE) matters a DriverManagerDataSource is used (see first code posting), and a JndiObjectFactoryBean (second one), if my Application is deployed on a JBoss?

custom applicationContext.xml datasources for JBoss
<bean id="activitiDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:jboss/datasources/activitiDataSource"/>
</bean>
<bean id="hibernateDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:jboss/datasources/hibernateDataSource"/>
</bean>
Any help is greatly appreciated.

Your application creates the database connection on its own as i can see on your config.
Instead of doing this you could just define the datasource on the app-server and obtain it by a jndi lookup. So you can configure the database connection for each system separately.
<!-- DataSource-LookUp -->
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean" scope="singleton">
<property name="jndiName" value="java:jboss/datasources/MyDataSourceDS" />
<property name="resourceRef" value="true" />
</bean>

Your JBoss has a file <jboss_home>/standalone/configuration/standalone.xml which is used if you don't provide a different one.
For testing purposes you could try and make a copy of that file in the same directory, e.g. naming it test.xml and add your datasource definition there. Then use it by starting JBoss with standalone.bat --server-config=test or standalone.bat -c test.

I managed to do this with a SVN patch, which is added prior to the automatic deployment. It changes the DataSource definitions.
Pay attention when creating the patch with windows and applying under linux with /usr/bin/patch (CR+LF problem, apply dos2unix filename to both patch and files to be patched).

Flyway DB Upgrader in Spring

I've a problem with the Flyway schema upgrader for Spring. Following code exists in my servlet.xml
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost/database"/>
<property name="username" value="root"/>
<property name="password" value="password"/>
</bean>
<bean id="flyway" class="com.googlecode.flyway.core.Flyway" init-method="migrate" depends-on="dataSource">
<property name="dataSource" ref="dataSource"/>
</bean>
But how to set the migration script directory or rather whats the default directory?

Everything is explained in the excellent documentation:
If you want to alter the default directory (which is db/migration as shown on the picture above), I believe this should work (see: Flyway.setBaseDir()):
<bean id="flyway" class="com.googlecode.flyway.core.Flyway" init-method="migrate" depends-on="dataSource">
<property name="dataSource" ref="dataSource"/>
<property name="baseDir" value="my/migrations/path"/>
</bean>
