Configuration

Option Name	Type	Required	Default	Description
location	String	Yes		The location of the properties file to resolve placeholders against, as a Spring resource location: a URL, a "classpath:" pseudo URL, or a relative file path. Multiple locations may be specified, separated by commas.
ignore-resource-not-found	boolean	No	false	Specifies if failure to find the property resource location should be ignored. Default is "false", meaning that if there is no file in the location specified an exception will be raised at runtime.
ignore-unresolvable	boolean	No	false	Specifies if failure to find the property value to replace a key should be ignored. Default is "false", meaning that this placeholder configurer will raise an exception if it cannot resolve a key. Set to "true" to allow the configurer to pass on the key to any others in the context that have not yet visited the key in question.
file-encoding	String	No		Specifies the encoding to use for parsing properties files. Default is none, using the java.util.Properties default encoding. Only applies to classic properties files, not to XML files.
