我正在尝试通过使用ConfigurationFactory
和这个参考来配置和设置Log4j2。我使用的代码如下:
public class LoggingConfiguration {
public static final String PATTERN_LAYOUT = "[%d] [%t] [%-5level] - %msg (%logger{1}:%L) %n%throwable";
public static final String LOG_FILE_NAME = "app.log";
public static final String LOG_FILE_NAME_PATTERN = LOG_FILE_NAME + "-yyyy.MM.dd";
static {
ConfigurationFactory.setConfigurationFactory(new Log4j2ConfigurationFactory());
}
/**
* Just to make JVM visit this class to initialize the static parts.
*/
public static void configure() {
}
@Plugin(category = "ConfigurationFactory", name = "Log4j2ConfigurationFactory")
@Order(0)
public static class Log4j2ConfigurationFactory extends ConfigurationFactory {
@Override
protected String[] getSupportedTypes() {
return null;
}
@Override
public Configuration getConfiguration(ConfigurationSource source) {
return new Log4j2Configuration();
}
@Override
public Configuration getConfiguration(String name, URI configLocation) {
return new Log4j2Configuration();
}
}
private static class Log4j2Configuration extends DefaultConfiguration {
public Log4j2Configuration() {
setName("app-log4j2");
String root = System.getProperty("APP_ROOT", "/tmp");
if (!root.endsWith("/")) {
root += "/";
}
// MARKER
Layout<? extends Serializable> layout = PatternLayout.createLayout(PATTERN_LAYOUT, null, null, null, null);
String oneDay = TimeUnit.DAYS.toMillis(1) + "";
String oneMB = (1024 * 1024) + "";
final TimeBasedTriggeringPolicy timeBasedTriggeringPolicy = TimeBasedTriggeringPolicy.createPolicy(oneDay,
"true");
final SizeBasedTriggeringPolicy sizeBasedTriggeringPolicy = SizeBasedTriggeringPolicy.createPolicy(oneMB);
final CompositeTriggeringPolicy policy = CompositeTriggeringPolicy.createPolicy(timeBasedTriggeringPolicy,
sizeBasedTriggeringPolicy);
final DefaultRolloverStrategy strategy = DefaultRolloverStrategy.createStrategy("7", "1", null,
Deflater.DEFAULT_COMPRESSION + "", this);
Appender appender = RollingFileAppender.createAppender(root + LOG_FILE_NAME, LOG_FILE_NAME_PATTERN, "true",
"app-log-file-appender", "true", "true", policy, strategy, layout, null, null, null, null, null);
addAppender(appender);
getRootLogger().addAppender(appender, Level.INFO, null);
}
}
}
请注意:
- 它扩展了默认配置控制台的
BaseConfiguration
- 它尝试向根记录器添加一个滚动文件附加程序
我得到了以下异常:

如果我将上面代码中
MARKER
后的代码注释掉,它能正常工作,但似乎我错过了一些配置滚动文件附加器的内容。我该怎么办才能解决这个问题?
