[jira] [Created] (CONFIGURATION-648) wrong property key:
PropertiesBuilderParametersImpl.PROP_IO_FACTORY
Attila Varga created CONFIGURATION-648:
------------------------------------------
Summary: wrong property key: PropertiesBuilderParametersImpl.PROP_IO_FACTORY
Key: CONFIGURATION-648
URL: https://issues.apache.org/jira/browse/CONFIGURATION-648
Project: Commons Configuration
Issue Type: Bug
Affects Versions: 2.1
Reporter: Attila Varga
Example in user guide about using custom IOFactory doesn't work.
Link:
https://commons.apache.org/proper/commons-configuration/userguide/howto_properties.html#Custom_properties_readers_and_writers
When you set an IOFactory like this:
params.properties()
.setFileName("myfile.properties")
.setIOFactory(new WhitespaceIOFactory())
this custom IOFactory won't be set in your PropertiesConfiguration because
the constant PropertiesBuilderParametersImpl.PROP_IO_FACTORY has the value:
"iOFactory".
FileBasedConfigurationBuilder tries to set the property "iOFactory" of PropertiesConfiguration .
The method setiOFactory() exists not.
I have found a workaround, maybe this can explain better the problem:
//New subclass:
public class PropertiesConfigurationOk extends PropertiesConfiguration {
public void setiOFactory(IOFactory ioFactory)
{
super.setIOFactory(ioFactory);
}
}
//Usage of new subclass:
FileBasedConfigurationBuilder<FileBasedConfiguration> builder = new FileBasedConfigurationBuilder<FileBasedConfiguration>(PropertiesConfigurationOk.class) .configure(propertiesBuilderParameters);
PropertiesConfiguration config = builder.getConfiguration();
