I am trying to create a custom appender for log4j 2.0, but am having issues getting my log4j configuration to recognize the appender. I know log4j 2.0 doesnt support packages in configuration attributes. So I tried, as suggested here, running the code with plain javac but even then it gives this error:2015-03-11 18:47:35,281 ERROR Error processing element Test: CLASS_NOT_FOUND
2015-03-11 18:47:35,307 ERROR Unable to locate appender test1 for logger
Here is my custom appender:
@Plugin(name = "Test", category = "Core", elementType = "appender", printObject = true)
public class TestAppender extends AbstractAppender{
protected TestAppender(String name, Filter filter,
Layout<? extends Serializable> layout, boolean ignoreExceptions) {
super(name, filter, layout, ignoreExceptions);
// TODO Auto-generated constructor stub
}
@PluginFactory
public static TestAppender createAppender(@PluginAttribute("name") String name,
@PluginAttribute("ignoreExceptions") boolean ignoreExceptions,
@PluginElement("Layout") Layout<? extends Serializable> layout,
@PluginElement("Filters") Filter filter) {
return new TestAppender(name, filter, layout, true);
}
public void append(LogEvent event) {
// TODO Auto-generated method stub
System.out.println(event.getMessage());
}
}
and my config xml:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN" >
<Appenders>
<Test name="test1" >
<PatternLayout pattern="%d %msg%n" />
<ThresholdFilter level="DEBUG" />
</Test>
</Appenders>
<Loggers>
<Root level="DEBUG">
<AppenderRef ref="test1" />
</Root>
</Loggers>
</Configuration>
Thanks in advance for any useful input
