replace properties from file found in classpath or either set via system.properties

[Torsten Reinhard]

Hi,

my AppContext.xml file need some configuration I want to provide in an external .properties file:

<bean id="myBean" class="myClass" >
<property name="password" value="${pwd}"/>
</bean>

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.Pr opertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>file:${external.properties}</value>
<value>classpath:default.properties</value>
</list>
</property>
<property name="ignoreResourceNotFound" value="true"/>
<property name="ignoreUnresolvablePlaceholders" value = "true"/>
</bean>


How can I configure the PropertyPlaceholderConfigurer to
1st check if the system property "external.properties" is set and than pick up this file and take the values from there
2nd try to read default.properties from classpath

Do I need to subclass PropertyPlaceholderConfigurer to implement this special behaviour? I guess there´s a recommended way to solve this.

thanx in advance,

Torsten

I use something like this:

   <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
        <property name="searchSystemEnvironment" value="true"/>
        <property name="ignoreResourceNotFound" value="true"/>
        <property name="ignoreUnresolvablePlaceholders" value="true"/>
        <property name="locations">
            <list>
                <value>classpath*:/xxx_application.properties</value>
                <value>classpath*:/xxx_jdbc.properties</value>
                <value>file:////etc/xxx_core.properties</value>
            </list>
        </property>
    </bean>
