Shortly after writing to this list, I hit on one solution.
If the Custom Appender is configured as described below :
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
<configuration>
<appender name="theCustomAppender" class="domain.TheCustomAppender">
<properties>
propertyName1=propertyValue1
propertyName2=propertyValue2
</properties>
</appender>
</configuration>
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Add a "Properties" getter and setter which uses a String argument.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
public String getProperties()
public setProperties(String propertiesString)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
When I need the Properties object, I simple do the following:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Properties properties = new Properties();
properties.load(new StringReader(propertiesString));
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Problem solved.
Feel free to reply to this thread, with an alternate solution that makes use of
a more Joran-oriented technique.
Thanks,

Subject: Custom Appender Configuration using generic Properties
Hi,
I have developed a custom appender for logback and would like to configure it
with a generic set of Properties that I can pass on to the underlying
libraries. Rather than create a Getter and Setter for each property that the
underlying library uses, I would like the configuration to read the *names* of
the properties out of the logback configuration file.
Instead of this:
<configuration>
<appender name="theCustomAppender" class="domian.TheCustomAppender">
<getterSetterProperty>value</getterSetterProperty>
</appender>
</configuration>
I would like to write something like this:
<configuration>
<appender name="theCustomAppender" class="domian.TheCustomAppender">
<properties class="java.util.Properties">
<property name="thisPropertyName" value="value" />
</properties>
</appender>
</configuration>
Does the Joran Configurator have the capability to parse a configuration file,
generate a Properties object, and then hand it off to the Appender?
I have looked around and have not been able to identify any guidance for this
use case. I have discovered the nested element capability and the "class"
attribute, but have not been able to build a mapped structure.
The north-west wind does feel a bit chilly, right now... :-)
Thanks,
John Page
