Log4j 1.x 到 Log4j 2.1.1 迁移问题

Question

我正在尝试将代码迁移到版本 2。但是，我在 log4j 2.1.1 中寻找 getCurrentLoggers 的替代方案时遇到了一些问题

import org.apache.logging.log4j.LogManager.getCurrentLoggers((; 不存在。

private ArrayList<LoggerName> getLoggerList() {
// Generate a list of all the loggers and levels
ArrayList<String> al = new ArrayList<String>();
HashMap<Object, Object> hm = new HashMap<Object, Object>();
ArrayList<LoggerName> list = new ArrayList<LoggerName>();
// Get RootLogger
Logger rootLogger = LogManager.getRootLogger();
String rootLoggerName = rootLogger.getName();
al.add(rootLoggerName);
hm.put(rootLoggerName, rootLogger);
// All Other Loggers ISSUE HERE
Enumeration e = LogManager.getCurrentLoggers();
while (e.hasMoreElements()) {               
Logger t1Logger = (Logger) e.nextElement();
String loggerName = t1Logger.getName();
al.add(loggerName);
hm.put(loggerName, t1Logger);       
}
String[] alLoggerStr = ((String[]) al.toArray(new String[0]));
Arrays.sort(alLoggerStr);
for (int i=0; i < alLoggerStr.length; i++) { 
Logger logger = (Logger) hm.get(alLoggerStr[i]);
String name = logger.getName();
String level = logger.getLevel().toString();
String parent = GenFuncs.EMPTY_STRING;
if (logger.getParent() != null) {
parent = (logger.getParent().getName();
}
LoggerName logData = new LoggerNameImpl(name, parent, level);
list.add(logData);
}
return list;
}

从堆栈溢出中找到答案

File configFile = new File("c:\my_path\log4j2.xml");
LoggerContext loggerContext = Configurator.initialize("my_config", null, configFile.toURI());
Configuration configuration = loggerContext.getConfiguration();
Collection<LoggerConfig> loggerConfigs = configuration.getLoggers().values();
