向生成增删改查2.2.aspect切面层2.3.Mybatis

generator逆向生成2.4.根据生成代码编写Biz层与实现类

三、controller层代码编写四、前台代码与分页代码五、案例测试

一、前期准备

--Console

控制台只输出level及以上级别的信息(onMatch),其他的直接拒绝(onMismatch)

--ThresholdFilter

//Console!--文件会打印出所有信息这个log每次运行程序会自动清空由append属性决定这个也挺有用的适合临时测试用

--!--append为TRUE表示消息增加到指定文件中false表示消息覆盖指定的文件内容默认值是true

--File

appendfalsePatternLayoutpattern%d{yyyy-MM-dd

HH:mm:ss.SSS}

这个会打印出所有的info及以下级别的信息每次大小超过size

则这size大小的日志会自动存入按年份-月份建立的文件夹下面并进行压缩作为存档

--RollingFile
