@Deprecated
public class ExtendedPropertySourcesPlaceholderConfigurer
extends org.springframework.context.support.PropertySourcesPlaceholderConfigurer

Custom extension of PropertySourcesPlaceholderConfigurer that serves three purposes:

• Override postProcessing to provide access to "local" properties before bean post-processing has completed
• Force configuration setting ignoreResourceNotFound=true and (safely) ignore noisy WARNings in the log concerning missing properties files that are optional
• Provide support for encrypted property values based on Jasypt

Method Detail

setIgnoreResourceNotFound

public void setIgnoreResourceNotFound(boolean value)

Deprecated.

Overrides:

setIgnoreResourceNotFound in class org.springframework.core.io.support.PropertiesLoaderSupport

setLocations

public void setLocations(org.springframework.core.io.Resource[] locations)

Deprecated.

uPortal defines some properties files in its primaryPropertyPlaceholderConfigurer bean that are considered (and documented) optional. The parent class (PropertySourcesPlaceholderConfigurer) will operate properly without them, but puts a significant number of WARN messages into the log. These are noisy, and could lead a new adopter to think that something's wrong. This method removes absent properties files from the collection.

Overrides:

setLocations in class org.springframework.core.io.support.PropertiesLoaderSupport

postProcessBeanFactory

public void postProcessBeanFactory(org.springframework.beans.factory.config.ConfigurableListableBeanFactory beanFactory)
                            throws org.springframework.beans.BeansException

Deprecated.

Override the postProcessing. The default PropertySourcesPlaceholderConfigurer does not inject local properties into the Environment object. It builds a local list of properties files and then uses a transient Resolver to resolve the @Value annotations. That means that you are unable to get to "local" properties (eg. portal.properties) after bean post-processing has completed unless you are going to re-parse those file. This is similar to what PropertiesManager does, but it uses all the property files configured, not just portal.properties. If we upgrade to spring 4, there are better/more efficient solutions available. I'm not aware of better solutions for spring 3.x.

Specified by:

postProcessBeanFactory in interface org.springframework.beans.factory.config.BeanFactoryPostProcessor

Overrides:

postProcessBeanFactory in class org.springframework.context.support.PropertySourcesPlaceholderConfigurer

Parameters:

beanFactory - the bean factory

Throws:

org.springframework.beans.BeansException - if an error occurs while loading properties or wiring up beans

getPropertyResolver

public org.springframework.core.env.PropertyResolver getPropertyResolver()

Deprecated.

Get a property resolver that can read local properties.

Returns:

a property resolver that can be used to dynamically read the merged property values configured in applicationContext.xml

mergeProperties

protected Properties mergeProperties()
                              throws IOException

Deprecated.

Override PropertiesLoaderSupport.mergeProprties in order to slip in a properly-configured EncryptableProperties instance, allowing us to encrypt property values at rest.

Overrides:

mergeProperties in class org.springframework.core.io.support.PropertiesLoaderSupport

Throws:

IOException
