getProperty
public String getProperty(String key)
Description copied from interface:PropertyResolverReturn the property value associated with the given key, ornullif the key cannot be resolved.- Specified by:
getPropertyin interfacePropertyResolver- Overrides:
getPropertyin classAbstractPropertyResolver- Parameters:
key- the property name to resolve- See Also:

getProperty
public <T> T getProperty(String key, Class<T> targetValueType)
Description copied from interface:PropertyResolverReturn the property value associated with the given key, ornullif the key cannot be resolved.- Parameters:
key- the property name to resolvetargetValueType- the expected type of the property value- See Also:
PropertyResolver.getRequiredProperty(String, Class)
getPropertyAsRawString
protected String getPropertyAsRawString(String key)
Description copied from class:AbstractPropertyResolverRetrieve the specified property as a raw String, i.e. without resolution of nested placeholders.- Specified by:
getPropertyAsRawStringin classAbstractPropertyResolver- Parameters:
key- the property name to resolve- Returns:
- the property value or
nullif none found

getPropertyAsClass
@Deprecated public <T> Class<T> getPropertyAsClass(String key, Class<T> targetValueType)
Deprecated.Description copied from interface:PropertyResolverConvert the property value associated with the given key to aClassof typeTornullif the key cannot be resolved.- Specified by:
getPropertyAsClassin interfacePropertyResolver- Overrides:

PropertyResolver.getProperty(String, Class)
logKeyFound
protected void logKeyFound(String key, PropertySource<?> propertySource, Object value)
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- thePropertySourcethat the key has been found invalue- the corresponding value- Since:
- 4.3.1
