Class DefaultPropertiesPersister

java.lang.Object

com.atlassian.extras.common.org.springframework.util.DefaultPropertiesPersister

public class DefaultPropertiesPersister
extends Object

Default implementation of the PropertiesPersister interface. Follows java.util.Properties native parsing.

Allows for reading from any Reader and writing to any Writer, for example to specify a charset for a properties file. This is a capability that standard java.util.Properties unfortunately lacks: You can only load files using the ISO-8859-1 charset there.

Loading from and storing to a stream delegates to Properties.load and Properties.store, respectively, to be fully compatible with the Unicode conversion as implemented by the JDK Properties class.

The persistence code that works with Reader/Writer follows the JDK's parsing strategy but does not implement Unicode conversion, because the Reader/Writer should already apply proper decoding/encoding of characters. If you use prefer to escape unicode characters in your properties files, do not specify an encoding for a Reader/Writer (like ReloadableResourceBundleMessageSource's "defaultEncoding" and "fileEncodings" properties).
