Use of the PropertyPlaceholderConfigurer within a WebContext

[awerner]

Hi,

i tried to use the PropertyPlaceholderConfigurer on a WebApplicationContext, but the replacement failed.

I used the following code:

PropertyPlaceholderConfigurer lConfigurer = null;
ApplicationContext lApplicationContext = null;
ConfigurableListableBeanFactory beanFactory = null;
Properties lProperties = null;

...

lApplicationContext = WebApplicationContextUtils.getWebApplicationContex t(
pRequestContext.getServlet().getServletContext());
lConfigurer = new PropertyPlaceholderConfigurer();
lConfigurer.setProperties(lProperties);
beanFactory = ((AbstractApplicationContext) lApplicationContext).getBeanFactory();
lConfigurer.postProcessBeanFactory(beanFactory);



Any ideas on whats going wrong/i did wrong are appreciated.

Regards,

Andreas Werner

You should be using it declaratively, since the application context has long since been created by the time you are trying to use the configurer on it. This is described here:

Hi,

I have the same problem (In Spring 2.0.4), but your link is brokken.
I use a webApplication like this :


private IFrontalService frontalService = null;
protected WebApplicationContext wac = null;

/* (non-Javadoc)
* @see org.apache.struts.action.Action#setServlet(org.apa che.struts.action.ActionServlet)
*/
public void setServlet(ActionServlet actionServlet) {
super.setServlet(actionServlet);

if (actionServlet != null) {
ServletContext servletContext = actionServlet.getServletContext();

this.wac = WebApplicationContextUtils
.getWebApplicationContext(servletContext);

this.frontalService = (IFrontalService) wac.getBean("frontalService");

}
}

and a spring configuration :


<bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyP laceholderConfigurer">
<property name="locations">
<list>
<value>classpath:frontal.properties</value>
</list>
</property>
<property name="ignoreUnresolvablePlaceholders"><value>true</value></property>
</bean>

<bean id="frontalService"
class="com.mypack.app.frontal.service.FrontalService">
<property name="wrapper">
<ref bean="wrapperTarget" />
</property>
<property name="urlBpm"><value>${url.wsdl.bpm}</value></property>
</bean>



My property file

url.wsdl.bpm = http://localhost:8080/APP-BPM/services/ExecutionManager?wsdl

In the "setServlet" method, when i get the bean "frontalService", the value of "urlBpm" is "${url.wsdl.bpm}".

Spring doesn't get the real value in my property file.

Is there a solution ?
Thanks

Is the properties file being found? If not, try using "classpath:/frontal.properties" (adding a slash).

Hi,

The properties file is found because when I deploy with another name, it's generate an IO exception : "Could not found file".

I may hope that the contents of your properties file isn't the context you posted?


url.wsdl.bpm = http://localhost:8080/APP-BPM/services/ExecutionManager?wsdl


Which means the name of your property is 'url.wsdl.bpm ' instead of 'url.wsdl.bpm' (notice the space!).

Next to that I would set the 'ignoreUnresolvablePlaceholders' to false so that if a placeholder cannot be replaced you will get an exception, now it simply ignores the fact that it cannot locate the property.

With 'url.wsdl.bpm = ' or 'url.wsdl.bpm=' or 'url.wsdl.bpm= ' the problem is the same. It doesn't replace the key.

Here my logs :
2008-03-26 09:55:39,217 {INFO } {commons.logging.impl.Log4JLogger} Loading properties file from class path resource [frontal.properties]
2008-03-26 09:55:39,217 {INFO } {commons.logging.impl.Log4JLogger} Loading properties file from class path resource [frontal.properties]

2008-03-26 09:55:39,220 {DEBUG} {commons.logging.impl.Log4JLogger} Resolved placeholder 'url.wsdl.bpm'

I haven't any exceptions

Are your beans loaded in the same ApplicationContext?

[FLM_25]

Yes i have just one application context
