containsProperty
Description copied from interface:PropertyResolver
Return whether the given property key is available for resolution, i.e. if the value for the given key is notnull
.- Specified by:
containsProperty
in interfacePropertyResolver
- Overrides:
containsProperty
in classAbstractPropertyResolver
-
getProperty
Description copied from interface:PropertyResolver
Return the property value associated with the given key, ornull
if the key cannot be resolved.- Specified by:
getProperty
in interfacePropertyResolver
- Overrides:
getProperty
in classAbstractPropertyResolver
- Parameters:
key
- the property name to resolve- See Also:

-
getPropertyAsRawString
Description copied from class:AbstractPropertyResolver
Retrieve the specified property as a raw String, i.e. without resolution of nested placeholders.- Specified by:
getPropertyAsRawString
in classAbstractPropertyResolver
- Parameters:
key
- the property name to resolve- Returns:
- the property value or
null
if none found
-
getProperty
-
logKeyFound
Log the given key as found in the givenPropertySource
, resulting in the given value.The default implementation writes a debug log message with key and source. As of 4.3.3, this does not log the value anymore in order to avoid accidental logging of sensitive settings. Subclasses may override this method to change the log level and/or log message, including the property's value if desired.
- Parameters:
key
- the key foundpropertySource
- thePropertySource
that the key has been found invalue
- the corresponding value- Since:
- 4.3.1
