ServletContextPropertyWroConfigurationFactory dont care about Spring WroProperties configuration

[Ludovic Dussart]

Hi all,

I use ConfigurableWroFilter to hot compile my less file. I use spring configuration to do that :

<!-- wro4j configuration -->

<bean id="wroFilter" class="ro.isdc.wro.http.ConfigurableWroFilter">

 <property name="properties" ref="wroProperties"/>

</bean>

<bean id="wroProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">

<!-- Pas d'exception si une des locations n'est pas trouvée -->

<property name="ignoreResourceNotFound" value="true" />

<property name="locations">

<list>

<!-- Valeurs par défaut (DEV) -->

<value>classpath*:META-INF/conf/wro.properties</value>

<!-- Surcharge des valeurs par défaut (les derniers locations surchargent les premiers)-->

<value>file:${PRODUCT_LOG_HOME:/product}/${APPLICATION_NAME:PROTOMOBILEV2}/conf/wro.properties</value>

</list>

</property>

</bean>

I have two locations for my wro.properties (external and in META-INF, not in WEB-INF)

It's works but i have an error in console for the ServletContextPropertyWroConfigurationFactory :

[FAIL] Cannot read properties file stream from default location: /WEB-INF/wro.properties. Using default configuration. 

How can i declare new location for this filter or prevent this error ? It is a important error ?

Thanks for yours solutions

The WroFilter is not very spring friendly, but this can be improved later. 

You can either ignore this error, or extend the WroFilter and override the following method: 

protected ObjectFactory<WroConfiguration> newWroConfigurationFactory(final FilterConfig filterConfig) {

    return new PropertyWroConfigurationFactory(myProperties);

}

The myProperties should be a reference to spring injected properties. 

Another approach is to set the WroConfiguration explicitly using WroFilter#setConfiguration method. In this case, it is your responsibility to create an instance of WroConfiguration.

Cheers,

Alex
