来源：互联网发布：数据库审计产品价格编辑：程序博客网时间：2024/05/17 07:00

导入log4j.jar 高版本的hibernate自带

在项目目录任意位置创建一个log4j.properties log4j是文件名可以任意起

然后在里面的配置可以参考下面的

对其中的代码对应的信息不了解的可以参考

在daoimpl实现类中

static Logger log = Logger.getLogger(yourclassName.class);

然后在方法内

log.info("开始执行 findByAAccount account="+account);

log.xxxx("xxxxx");
