Patrick Buchheit updated CONFIGURATION-811:
-------------------------------------------
Description:
I'm working on a project that needs to define and load some properties as
delimited lists of strings. I noticed that when I went to load my properties
from the configuration, the resulting string has escape characters added before
each delimiter. So if my property file has the line
*[email protected]@[[email protected]|mailto:[email protected]]*
then the result of looking up the property will be
*[email protected]/-foo@[tura.com/[email protected]|mailto:[email protected]]*
I'm not sure whether this behaviour is intentional or a bug, but it causes
problems when trying to use the 'split()' method of
AbstractListDelimiterHandler. The escape character causes the delimiter to be
treated as a literal, so the string does not get split into parts. Below is a
test case demonstrating the behaviour I'm seeing.
{code:java}
@Test
public void testPropertyParsingWithEscape() throws IOException,
ConfigurationException
{
File tmpOutput = File.createTempFile("test", ".properties");
Writer out = new FileWriter(tmpOutput);
out.write("[email protected][email protected][email protected]");
out.append("\[email protected]\\[email protected]");
out.append("\[email protected]\\\\[email protected]");
out.close();
Configurations configurations = new Configurations();
CompositeConfiguration cc = new CompositeConfiguration();
ListDelimiterHandler handler = new DefaultListDelimiterHandler('-');
cc.setListDelimiterHandler(handler);
cc.addConfiguration(configurations.properties(tmpOutput));
Configuration config = cc;
final Properties props = ConfigurationConverter.getProperties(config);
String navTo = (String) props.get("mail.to.nav");
assertNotNull(navTo);
String errorTo = (String) props.get("mail.to.error");
assertNotNull(errorTo);
String to = (String) props.get("mail.to");
assertNotNull(to);
List<String> lst1 = (List<String>) handler.split(navTo, true);
List<String> lst2 = (List<String>) handler.split(errorTo, true);
List<String> lst3 = (List<String>) handler.split(to, true);
assertThat(lst1, contains(
Arrays.asList("[email protected]","[email protected]","[email protected]")) );
assertThat(lst2, contains( Arrays.asList("[email protected]","[email protected]"))
);
assertThat(lst3, contains( Arrays.asList("[email protected]","[email protected]"))
);
}
