conda环境迁移
打包某个python环境在打包之前如果没有conda-pack包的话，需要安装pip install conda-pack
进行python环境打包：1conda pack -n py36 -o py366.tar.gz
Py36是需要打包的已存在的python环境，py366.tar.gz是我们打包后压缩包的名称
使用包解压缩py366.tar.gz:
12mkdir py366tar -zxvf py366.tar.gz -C py366
激活环境：
1conda activate py366
分享虚拟环境conda方式导出当前虚拟环境
1conda env export > environment.yml
创建保存的虚拟环境
1conda env create -f environment.yml
pip方式12pip freeze > requirements.txtpip install -r requirements.txt

spring 切入点表达式
切入点表达式切入点表达式作用：知道对哪个类里面的哪个方法进行增强语法结构： execution(<权限修饰符> <返回类型> <类全路径> <方法名称>(<参数列表>) )
举例 1：对 com.atguigu.dao.BookDao 类里面的 add 进行增强1execution(* com.atguigu.dao.BookDao.add(..))
举例 2：对 com.atguigu.dao.BookDao 类里面的所有的方法进行增强1execution(* com.atguigu.dao.BookDao.* (..))
举例 3：对 com.atguigu.dao 包里面所有类，类里面所有方法进行增强1execution(* com.atguigu.dao.*.* (..))
spring AOP 注解开发
AOP 操作（AspectJ 注解）1. 创建类，在类里面定义方法1234public class User { public void add() { System.out.println("add......."); } }
2. 创建增强类（编写增强逻辑）123456//（1）在增强类里面，创建方法，让不同方法代表不同通知类型//增强的类public class UserProxy { public void before() {//前置通知 System.out.println("before......");}
3. 进行通知的配置
在 spring 配置文件中，开启注解扫描12345678910111213<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/bean ...
