[spring] spring PropertyPlaceholderConfigurer and context:property-placeholder

I have following bean declaration:

  <bean
     class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>WEB-INF/classes/config/properties/database.properties</value>
                <value>classpath:config/properties/database.properties</value>
            </list>
        </property>
        <property name="ignoreResourceNotFound" value="true"/>
    </bean>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="${jdbc.driverClassName}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
</bean>

Now I want to change above PropertyPlaceholderConfigurer to following format:

<context:component-scan base-package="org.example.config"/>
<util:properties id="jdbcProperties" 
           location="classpath:config/properties/database.properties"/>
  1. ignoreResourceNotFound will ignore the property while running. e.g: When testing application WEB-INF/.. path will ignore( since maven project and property file is under src/main/resources/..), while launching web application, other property will ignore path, I need to implement same with above format.
  2. should be able to add multiple property file like database.properties, test.properties etc.
  3. in Spring 3, can I use annotation instead of these xml files for DB loading, how can I do it? since I am using only one xml file(given above) to load db stuff.

I am using Spring 3 framework.

This question is related to spring

The answer is


First, you don't need to define both of those locations. Just use classpath:config/properties/database.properties. In a WAR, WEB-INF/classes is a classpath entry, so it will work just fine.

After that, I think what you mean is you want to use Spring's schema-based configuration to create a configurer. That would go like this:

<context:property-placeholder location="classpath:config/properties/database.properties"/>

Note that you don't need to "ignoreResourceNotFound" anymore. If you need to define the properties separately using util:properties:

<context:property-placeholder properties-ref="jdbcProperties" ignore-resource-not-found="true"/>

There's usually not any reason to define them separately, though.


Following worked for me:
<context:property-placeholder location="file:src/resources/spring/AppController.properties"/>

Somehow "classpath:xxx" is not picking the file.
