Spring Core 6.1.4 · org.springframework.util.DefaultPropertiesPersister

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

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 lacked up until JDK 5: You were only able to 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. As of JDK 6, Properties.load/store is also used for readers/writers, effectively turning this class into a plain backwards compatibility adapter.

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 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).
