修改org.slf4j.Logger时，修改默认配置文件位置

File logbackFile = new File(ConstantsTools.PATH_LOG_CONFIG);
if (logbackFile.exists()) {
    LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
    JoranConfigurator configurator = new JoranConfigurator();
    configurator.setContext(lc);
    lc.reset();
    try {
        configurator.doConfigure(logbackFile);
    }
    catch (JoranException e) {
        e.printStackTrace(System.err);
        System.exit(-1);
    }
}
