Question

我有这个Log4J配置，可以在日志文件中生成消息：

log = Logger.getLogger(LogMessages.class.getName());
        BasicConfigurator.configure();  // Basic configuration for Log4J 1.x

        ConsoleAppender console = new ConsoleAppender(); //create appender
        //configure the appender
        String PATTERN = "%d{DATE} [%p|%c|%C{1}] %m%n";
        console.setLayout(new PatternLayout(PATTERN));
        console.setThreshold(Level.FATAL);
        console.activateOptions();
        //add appender to any Logger (here is root)
        Logger.getRootLogger().addAppender(console);

        DailyRollingFileAppender fa = new DailyRollingFileAppender();
        fa.setName("FileLogger");
        fa.setFile("log" + File.separator + "messages.log");
        fa.setDatePattern("'.'yyyy-MM-dd");
        fa.setLayout(new PatternLayout("%d %-5p [%c{1}] %m%n"));
        fa.setThreshold(Level.DEBUG);
        fa.setAppend(true);
        fa.activateOptions();

        //add appender to any Logger (here is root)
        Logger.getRootLogger().addAppender(fa); //repeat with all other desired appenders

这是生成的输出：

2013-12-26 10:19:27,501 WARN  [LogMessages] test_message

我想生成这样的信息：

2013-12-26 10:19:27 WARN test_message

如何从邮件中删除[LogMessages]？

对于文件记录，请将setLayout调用更改为：

fa.setLayout(new PatternLayout("%d{dd/MM/yyyy HH\:mm\:ss} %-5p %m%n"));

对于控制台日志记录，请使用相同的模式：

String PATTERN = "%d{dd/MM/yyyy HH\:mm\:ss} %-5p %m%n";

在Log4J中设置消息模式
