Logger代码如下:
...
Logger log = Logger.getLogger("myApp");
log.setLevel(Level.ALL);
log.info("initializing - trying to load configuration file ...");
Properties preferences = new Properties();
try {
FileInputStream configFile = new FileInputStream("/path/to/app.properties");
preferences.load(configFile);
LogManager.getLogManager().readConfiguration(configFile);
} catch (IOException ex)
{
System.out.println("WARNING: Could not open configuration file");
System.out.println("WARNING: Logging not configured (console output only)");
}
log.info("starting myApp");
...
这是配置文件:
appconfig1 = foo
appconfig2 = bar
