[Configuration] Bug with XMLConfiguration and getString() ...?!
Hi guys,
I've got the following problem:
I've got a xml-config-file with that content:
<?xml version="1.0" encoding="UTF-8"?>
<config>
...
<sftp>
<host>myhost</host>
<port>22</port>
<user>testuser</user>
<pass>08,15</pass>
</sftp>
...
</config>
In my application I get the info about pass f.e. like this
String pass = xml_config.getString("sftp.pass");
value of pass: '08' and not '08,15'
I know, that ',' is the default-decollator für list-entries, but I think it shouldn't affect the getString()-Method ?!
So it might be a bug?!
Thanks,
Markus

+1000, really looking forward to 2.0

ok. you're right ... rtfm ...
but there are some other solutions, too ... (if I would look at the api-docs ...)
a) you can set the listDelimiter to another sign
b) you can escape the delimiter sign f.e. <pass>08\,15<pass>
so anyway... it works and thanks for your help.

There are two workarounds:
- You can change the character used as list delimiter using the
setListDelimiter() method (or even globally using
AbstractConfiguration.setDefaultListDelimiter()).
- List delimiters in strings can be escaped with a backslash. Your
property value could be changed to "08\,15".

You have to call setDelimiterParsingDisabled(true) before you load the
configuration. The processing of list elements is done during parsing of
the configuration file. This is also mentioned in the Javadocs of the
setDelimiterParsingDisabled() method.

Hi Oliver,
nice feature, but there are problems ...
a) if you have both, list-entries and simple entries with decollator-signs I think you have to disable/enable this feature each time ... ok, better than nothing. If there are compatibility reasons, I agree but...
b) for me it doesn't work as described
f.e. I've got this code ...
private static XMLConfiguration xml_config;
/**
* inits the configuration
*/
private static void initConfiguration() {
try {
xml_config = new XMLConfiguration(ApplicationContext.class.getResource(APPLICATION_CONFIG));
} catch (ConfigurationException ex) {
ex.printStackTrace();
}
}
/**
* static inner class for SFTP-params
*/
static class SFTPParamObj {
public String host = xml_config.getString("sftp.host");
public String port = xml_config.getString("sftp.port");
public String user = xml_config.getString("sftp.user");
public String pass = getPasswd();
/**
* @return
*/
private String getPasswd() {
xml_config.setDelimiterParsingDisabled(true);
String pass = xml_config.getString("sftp.pass");
xml_config.setDelimiterParsingDisabled(false);
return pass;
}
}
and the result of pass: 08 !!!
What's wrong ???
Thanks,
Markus

You can disable this behavior by calling
xml_config.setDelimiterParsingDisabled(true);
That said, I fully agree that the default behavior is confusing - I fell
into this trap more than once myself. For reasons of backwards
compatibility we cannot change this in the 1.x series. But in a 2.0
version I am happy to disable delimiter parsing per default.

Actually, it works as designed. getString() delivers the first list entry. And I am sure, that quite everyone will consider this as a bug ... it makes no sense to me either :-/
