Apache Camel - Read JDBC dataSource properties from properties file using spring

Question

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.

Answer 1

url = my_url属性名称=“ URL” value =“ $ {url}”

Answer 2

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>

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):
