乱花渐欲迷人眼,浅草才能没马蹄。
折腾一晚上，问题总算时解决了。心里倒是没有多舒服，真相有时候还蛮伤人的。
前几天，面试时，跟两个项目经理聊起来几个技术实际应用和底层原理。一位老哥指着项目组的人说“你看看这些人，你让他做，他也能做。可你问他为什么这样做，没几个能说明白的。“。“我问你原理有什么用，没用，就是看看你对这个事情的理解。”
基于这样的情况，我决定把几个事故多发地着重关注一下。
先从全家桶基石的两大核心下手。
昨天跟蛋蛋哥哥，说起来AOP的几种应用，突然间来了兴致。
开发工具：idea+maven+ssm
需求：使用aop实现日志打印功能，对controller种的操作进行记录。
1.首先创建项目：File-new-project-maven
finish，完成，等待maven依赖加载完。
2.创建相关的包，完善项目结构。以下为初始项目结构：
之后建立相关的包，然后再File-ProjectStructure中指定各文件属性。
3.数据库脚本如下（脚本附件不知道怎么添加，下边sql早数据库执行即可）：
/*
SQLyog Ultimate v9.62
MySQL - 5.5.55
/
/!40101 SET NAMES utf8 */;
create table user (
id int (11),
name varchar (60),
age int (11),
sex varchar (30)
);
insert into user (id, name, age, sex) values(‘1’,‘蛋蛋’,‘22’,‘男’);
insert into user (id, name, age, sex) values(‘2’,‘山山’,‘21’,‘男’); 4.各种类的代码
创建各种类，不详细展开了。
实体类：
package com.scbg.pojo;
/**
*
* Author:三层饼干儿
* Date :2019-07-27
*/
public class User {
private int id;
private String name;
private int age;
private String sex;
public User() {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", name='" + name + '\'' +
", age=" + age +
", sex='" + sex + '\'' +
'}';
}
}Dao层接口：

}
public Object update() {
Map param = new HashMap();
param.put("total",10);
param.put("name","测试一");
userMapper.update(param);
return "OK";
}

<!–PROPAGATION_MANDATORY：支持当前事务，如果当前没有事务，就抛出异常。–>
<!–PROPAGATION_REQUIRES_NEW：新建事务，如果当前存在事务，把当前事务挂起。–>
<!–PROPAGATION_NOT_SUPPORTED：以非事务方式执行操作，如果当前存在事务，就把当前事务挂起。–>
<!–PROPAGATION_NEVER：以非事务方式执行，如果当前存在事务，则抛出异常。–>
<!–PROPAGATION_NESTED：支持当前事务，如果当前事务存在，则执行一个嵌套事务，如果当前没有事务，就新建一个事务。–>
