如果用的logback实现，就用

ch.qos.logback.classic.Logger root = (ch.qos.logback.classic.Logger) org.slf4j.LoggerFactory .getLogger(ch.qos.logback.classic.Logger.ROOT_LOGGER_NAME); root.setLevel(Level.INFO); 1 2 3 如果用的是log4j实现，就用

org.apache.log4j.Logger.getRootLogger().setLevel(Level.INFO);
BasicConfigurator.configure(new ConsoleAppender(
        new ColorPatternLayout("%d{MM-dd HH:mm:ss} [%-25t] %-5p: %m%n")));
