the java source or test resources folder?

I found I couldn't switch to log4j. |

发帖数: 8443 | 7 in the code, I set up like this:
private static void setupLogger(){
m_log.setLevel(Level.ALL);
try {
FileHandler fhandler = new FileHandler("E:\logs\service.log");
SimpleFormatter sformatter = new SimpleFormatter();
fhandler.setFormatter(sformatter);
m_log.addHandler(fhandler);
} catch (IOException ex) {
m_log.log(Level.SEVERE, ex.getMessage(), ex);
} catch (SecurityException ex) {
m_log.log(Level.SEVERE, ex.getMessage(), ex);
}
}
static {
setupLogger();
}
// but then how I know it is production or unit testing? how to enable
logging globally? |

发帖数: 8443 | 8 I added the logging.properties to classpath, it is not working.
handlers=java.util.logging.FileHandler, java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=INFO
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
java.util.logging.FileHandler.level=INFO
java.util.logging.FileHandler.pattern=logs/jetty.log
# Write 10MB before rotating this file
java.util.logging.FileHandler.limit=10000000
# Number of rotating files to be used
java.util.logging.FileHandler.count=4
java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter
.level=INFO |

我建议上aspectj
如果你会用的话，就可以很容易滴将log代码和真正逻辑代码分离 |

发帖数: 8443 | 10 我们是个小公司，没有什么framework，已经用了java.util.logging.Logger, 还可以
用log4j吗? 怎么set up aspectj? 怎么分离log和真正的代码？log on method entry
point? what about to log some business logic inside the method? |

发帖数: 8443 | 11 I don't understand
Logger.getLogger(getClass().getName())
it seems creating so many logger is unnecessary. why not keep only one
Logger?
coz then it only has one place to add the Handler:
m_log.addHandler(fhandler);
otherwise it has to go to so many different logger and for each one, add the
FileHandler.
I am confused of Java. |

发帖数: 8443 | 12 there should be a global logger:
static public void setup() throws IOException {
// Get the global logger to configure it
Logger logger = Logger.getLogger(Logger.GLOBAL_LOGGER_NAME);
logger.setLevel(Level.INFO);
fileTxt = new FileHandler("Logging.txt");
fileHTML = new FileHandler("Logging.html");
// Create txt Formatter
formatterTxt = new SimpleFormatter();
fileTxt.setFormatter(formatterTxt);
logger.addHandler(fileTxt);
// Create HTML Formatter
formatterHTML = new MyHtmlFormatter();
fileHTML.setFormatter(formatterHTML);
logger.addHandler(fileHTML);
} |
