怎么快速搭建一个SSM框架？很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
一、我用的是idea
二、首先创建一个maven项目，结构如下:
三、开始写配置文件
pom文件

MANDATORY：支持当前事务，如果当前没有事务，就抛出异常。
REQUIRES_NEW：新建事务，如果当前存在事务，把当前事务挂起。
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。
NEVER：以非事务方式执行，如果当前存在事务，则抛出异常。
NESTED：支持当前事务，如果当前事务存在，则执行一个嵌套事务（还不是太明白），如果当前没有事务，就新建一个事务。
