	Springmvc中的拦截器
i.	自定义拦截器
ii.	配置拦截器的拦截范围

SSM整合
a>	搭建mybatis的运行环境
b>	搭建springioc的运行环境
c>	整合mybatis和spring (1.sqlSessionFactory,2.mappersacnnerConfigurer,3.事务 )
d>	搭建springmvc的运行环境
e>	整合ssm

方式一:将所有内容交给springmvc容器管理
方式二:使用监听器加载spring容器

1. Recalls MAVEN basis
dependency management: automated engineering all depend jar package to download
a key building: Use a series of commands maven provide complete test project, compile, package, deploy, operate, function

1.1 Maven command
Clean
the compile
the Test
Package Penalty for
install
Deploy: to publish the project to PW

1.2 JBLJavatoWeb plug
an ordinary jar project: a packaging jar
Web project: a packaging war

2. The transfer dependent
transfer dependency: A project depends on B, B project depends on C, the item A is indirectly dependent on C

2.1 dependent solution of the conflict

2.1.1 rely on the principles of mediation
first statement finite principle: who should configure, who will use
the path recently, the principle of priority: to find the corresponding path dependence from the project, that near the

3.2 Procedure

polymerization Engineering:
Split: three-layer structure according to the resolution (web, service, dao)
Polymerization: unified for all sub-modules through the parent project management

Inheritance: sub-module can inherit all the coordinates of the parent project as defined in

4.Ssm integrated Case
