log4j MDC将日志数据插入数据库

static Logger logger = Logger.getLogger(this.class);


MDC.put("id", id);
MDC.put("returncode", recode);
MDC.put("type", "3");
MDC.put("msg", mes);
MDC.put("unit", unit);

logger.info("用来驱动，不然MDC无法保存");


以上是在方法体内的将需要插入数据库内的数据用MDC（类似map(key/value)）保存

log4j.properties   中配置存入数据库
