I need to load datasource properties from properties file
db.properties:
url = my_url
user = user_name
password = user_pass
this is dataSource (camelcontext.xml):
I'm trying like this, it is not working.
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations" value="classpath:db.properties"/> </bean>
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="${url}"/>
<property name="user" value="${user}"/>
<property name="password" value="${pasword}"/>
</bean>
My routes are implemented in java dsl.
In order to use Camel Properties in Spring XML, you have to add the following Spring bean with the ID 'properties'
<bean id="properties"
class="org.apache.camel.component.properties.PropertiesComponent">
<property name="location" value="classpath:db.properties"/>
</bean>
OR (after your comment please try this):
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="${url}"/>
<property name="user" value="${user}"/>
<property name="password" value="${pasword}"/>
</bean>
<context:property-placeholder properties-ref="properties"/>
<util:properties id="properties" location="classpath:db.properties"/>
url = my_url
property name="URL" value="${url}"
When using the expression language like ${...} you have to reference the keys of your property file, not the values. You propably want to write s.th. like
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="${url}"/>
<property name="user" value="${user}"/>
<property name="password" value="${password}"/>
</bean>

I searched for how to configure spring with tomcat I found that I have to put the following loader into context
<Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>
And I have to put spring-instrument-tomcat-x.x.jar into the tomcat lib folder
applicationContext.xml

But I know there is another methodology to configure spring without using context loader or putting the jar into tomcat lib folder
Any ideas how to do that
Thanks in advance

I couldnt find answer for my answer anywhere.
In my pom.xml i have this dependency:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.31</version>
</dependency>
On local connection I dont have such problem, here is my local bean setup:
<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:3306/test" />
<property name="username" value="root" />
<property name="password" value="" />
</bean>
I think the problem should be with the host you are specifying there, "localhost" doesn't seem right for an external database.
This Openshift guide might be helpful:

Before I added the spring-data-jpa to the spring config.xml everything worked fine. Why isn't the xml not valid anymore?

I am trying to access a property file containing db configurations in a Maven + Spring project.
I get following error:
Cannot load JDBC driver class '${db_driver}'
My Property file is placed in src/resources folder.
Below is the tag to load property files:
<bean id="dbPropertyReader"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="order" value="1" />
<property name="locations">
<value>classpath:${appenv.deployment}.properties</value>
</property>
</bean>
Following tag uses properties loaded:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="url" value="${db_url}" />
<property name="driverClassName" value="${db_driver}" />
<property name="username" value="${db_username}" />
<property name="password" value="${db_password}" />
</bean>
Below are contents of properties file:
#JDBC Properties
db_driver=com.mysql.jdbc.Driver
db_url=jdbc\:mysql\://hostname\:3306/xxx_dbxxx?useUnicode\=true
db_username=abcdefgh
db_password=ijklmnopq
db_removeabadoned=true
db_initialsize=1
db_maxactive=2
${appenv.deployment} is a VMArgument set as follows:
-Dappenv.deployment=development
I have checked, this value is getting populated properly.
I am getting following line in logs:
Found key 'appenv.deployment' in [systemProperties] with type [String] and value 'development'
Then after this I am also getting following:
Loading properties file from class path resource [development.properties]
But some how, the values are not getting loaded.

I am loading applicationContext.xml with following statement in code:
`appContext = new ClassPathXmlApplicationContext("applicationContext.xml");`
applicationContext.xml imports generic.xml.
generic.xml imports Spring-DataSource.xml.
have you added this to your application context file
<context:property-placeholder location="Path for .properties file"/>
add this line before the beans
I am using an XML configuration file that is loaded into my Java application using ApplicationContext.
The XML configuration file resolves its properties by reading from several property files using PropertyPlaceholderConfigurer.
I want to make each property file optional. I thought that this is done by setting ignoreUnresolsvablePlaceholders to true, however I am getting the following exception when I run the application (db-default.properties exists but db.properties does not):
Exception in thread "main" org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException: class path resource [db.properties] cannot be opened because it does not exist
This is what my XML configuration looks like:

What do I need to do to make db.properties an optional property file?
<property name="ignoreResourceNotFound" value="true"/>

This should work too:
<context:property-placeholder ignore-resource-not-found="true" location="classpath:your.properties" ... />
