Summary: Using AppenderComponentBuilder to Build an
OutputStreamAppender
Key: LOG4J2-2888
URL: https://issues.apache.org/jira/browse/LOG4J2-2888
Project: Log4j 2
Issue Type: Question
Components: Configuration, Configurators
Reporter: Daniel Resch
Hi all,
I would like to programmatically create a configuration for an
OutputStreamAppender using the AppenderComponentBuilder approach. I need to set
the target output stream, but the .addAttribute("target", myOutputStream)
method doesn't work. I have the following static method below:
public static void configureTextStackLogger() {
ConfigurationBuilder<BuiltConfiguration> builder =
ConfigurationBuilderFactory.newConfigurationBuilder();
builder.setStatusLevel(Level.ERROR); builder.setConfigurationName("MyApp");
builder.add(builder.newFilter("ThresholdFilter", Filter.Result.ACCEPT,
Filter.Result.NEUTRAL) .addAttribute("level", Level.DEBUG));
AppenderComponentBuilder appenderBuilder = builder.newAppender("MyTextStack",
"OutputStream"); appenderBuilder.add(builder.newLayout("PatternLayout")
.addAttribute("pattern", "%d [%t] %-5level: %msg%n%throwable"));
OutputStreamAppender osa = (OutputStreamAppender
(appenderBuilder.getBuilder()))
appenderBuilder.add(builder.newFilter("MarkerFilter", Filter.Result.DENY,
Filter.Result.NEUTRAL) .addAttribute("marker", "FLOW"));
builder.add(appenderBuilder);
builder.add(builder.newLogger("com.my.app", Level.INFO)
.add(builder.newAppenderRef("MyTextStack")).addAttribute("additivity", false));
builder.add(builder.newRootLogger(Level.ERROR).add(builder.newAppenderRef("MyTextStack")));
Configurator.initialize(builder.build());
}
What do I need to do to call the setTarget in OutputStreamAppender.Builder
method so I can add my OutputStream?
