public abstract class PropertyResourceConfigurer extends PropertiesLoaderSupport implements BeanFactoryPostProcessor, PriorityOrdered
Two concrete implementations are provided in the distribution:
PropertyOverrideConfigurer
for "beanName.property=value" style overriding
(pushing values from a properties file into bean definitions)
PropertyPlaceholderConfigurer
for replacing "${...}" placeholders
(pulling values from a properties file into bean definitions)
Property values can be converted after reading them in, through overriding
the convertPropertyValue(java.lang.String)
method. For example, encrypted values
can be detected and decrypted accordingly before processing them.

convertProperties(Properties props)
Convert the given merged properties, converting property values
if necessary.

protected String |
convertProperty(String propertyName,
String propertyValue)
Convert the given property from the properties source to the value
which should be applied.
|
protected String |
convertPropertyValue(String originalValue)
Convert the given property value from the properties source to the value
which should be applied.

Return the order value of this object, with a
higher value meaning greater in terms of sorting.

protected abstract void |
processProperties(ConfigurableListableBeanFactory beanFactory,

Apply the given Properties to the given BeanFactory.

Set the order value of this object for sorting purposes.

PriorityOrdered
public int getOrder()
Ordered
Normally starting with 0, with Integer.MAX_VALUE
indicating the greatest value. Same order values will result
in arbitrary positions for the affected objects.
Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).
public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException

beanFactory
- the bean factory used by the application contextBeanInitializationException
- if any properties cannot be loadedBeansException
- in case of errorsprotected void convertProperties(Properties props)
The default implementation will invoke convertPropertyValue(java.lang.String)
for each property value, replacing the original with the converted value.
props
- the Properties to convertprocessProperties(org.springframework.beans.factory.config.ConfigurableListableBeanFactory, java.util.Properties)
protected String convertProperty(String propertyName, String propertyValue)
The default implementation calls convertPropertyValue(String)
.
propertyName
- the name of the property that the value is defined forpropertyValue
- the original value from the properties sourceconvertPropertyValue(String)
protected String convertPropertyValue(String originalValue)
The default implementation simply returns the original value. Can be overridden in subclasses, for example to detect encrypted values and decrypt them accordingly.
originalValue
- the original value from the properties source
