Sql server MS SQL Server的Log4J JDBCAppender异常

我使用以下代码获得一个使用log4j的DB记录器

            PatternLayout layout = new PatternLayout();

            JDBCAppender jdbcAppender = new JDBCAppender();
            jdbcAppender.setDriver(jdbc);
            jdbcAppender.setUser(user);
            jdbcAppender.setPassword(password);
            jdbcAppender.setURL(url);
            jdbcAppender
                    .setSql("INSERT INTO " + logTable + " VALUES('%x', '%d', '%C', '%p', '%m')");
            jdbcAppender.setLayout(layout);
            jdbcAppender.activateOptions();

            Logger rootLogger = Logger.getRootLogger();
            rootLogger.setLevel(Level.DEBUG);
            rootLogger.addAppender(jdbcAppender);

            Logger logger = Logger.getLogger(type);

日志记录引发异常：

logger.info（“这是日志”）
