PreferencesPlaceholderConfigurer

public class PreferencesPlaceholderConfigurer extends PropertyPlaceholderConfigurer implements InitializingBean(Code)

Subclass of PropertyPlaceholderConfigurer that supports JDK 1.4's Preferences API (java.util.prefs).

Tries to resolve placeholders as keys first in the user preferences, then in the system preferences, then in this configurer's properties. Thus, behaves like PropertyPlaceholderConfigurer if no corresponding preferences defined.

Supports custom paths for the system and user preferences trees. Also supports custom paths specified in placeholders ("myPath/myPlaceholderKey"). Uses the respective root node if not specified.

Method Summary
public void	afterPropertiesSet() This implementation eagerly fetches the Preferences instances for the required system and user tree nodes.
protected String	resolvePlaceholder(String placeholder, Properties props) This implementation tries to resolve placeholders as keys first in the user preferences, then in the system preferences, then in the passed-in properties.
protected String	resolvePlaceholder(String path, String key, Preferences preferences) Resolve the given path and key against the given Preferences.
public void	setSystemTreePath(String systemTreePath) Set the path in the system preferences tree to use for resolving placeholders.
public void	setUserTreePath(String userTreePath) Set the path in the system preferences tree to use for resolving placeholders.

Method Detail

afterPropertiesSet
public void afterPropertiesSet()(Code)
	This implementation eagerly fetches the Preferences instances for the required system and user tree nodes.

resolvePlaceholder
protected String resolvePlaceholder(String placeholder, Properties props)(Code)
	This implementation tries to resolve placeholders as keys first in the user preferences, then in the system preferences, then in the passed-in properties.

resolvePlaceholder
protected String resolvePlaceholder(String path, String key, Preferences preferences)(Code)
	Resolve the given path and key against the given Preferences. Parameters: path - the preferences path (placeholder part before '/') Parameters: key - the preferences key (placeholder part after '/') Parameters: preferences - the Preferences to resolve against the value for the placeholder, or `null` if none found

setSystemTreePath
public void setSystemTreePath(String systemTreePath)(Code)
	Set the path in the system preferences tree to use for resolving placeholders. Default is the root node.

setUserTreePath
public void setUserTreePath(String userTreePath)(Code)
	Set the path in the system preferences tree to use for resolving placeholders. Default is the root node.
