===================================================== 搭建环镜
    
    一、数据库
    	mysql> create database itcastoa default character set utf8;
    	Query OK, 1 row affected (0.00 sec)
    	mysql> show create database itcastoa;
    	+----------+-------------------------------------------------------------------+
    	| Database | Create Database                                                   |
    	+----------+-------------------------------------------------------------------+
    	| itcastoa | CREATE DATABASE `itcastoa` /*!40100 DEFAULT CHARACTER SET utf8 */ |
    	+----------+-------------------------------------------------------------------+
    	1 row in set (0.00 sec)	
    	
    二、MyEclipse工程
    	1,新建Web工程,并把编码设为utf-8
    		右键项目 --> Properties --> Resource --> (右边)Other:UTF-8
    	2,添加框架环境
    		Junit --> 右键项目 --> Build Path --> Add Library --> JUnit 
    		Struts2 --> 加jar包 --> 拷配置文件 --> 写配置文件内容
    		Hibernate
    		Spring
    	3,整合SSH
    		Struts2与Spring整合
    		Hibernate与Spring整合
    	4,资源分类
    	5,配置日志
    		
    Struts2
    	jar包
    	struts.xml,web.xml  
    Hibernate	
    	jar包:核心包,必须包,jpa,c3p0,jdbc
    	hibernate.cfg.xml,*.hbm.xml
    Spring
    	jar包
    	application.xml/beans.xml
    
    声明一个bean	
    	@Component("beanName") --> 
    	@Controller("beanName") --> 控制层
    	@Service("beanName") --> 业务层
    	@Repository("beanName") --> 持久层
    
    配置bean的scope(生命)周期
    	@Scope("prototype")
    
    注入bean
    	@Resource
    
    Spring与Struts2整合
    	1,在web.xml中配置Spring的监听器
    	2,加一个jar包
    
    Hibernate与Spring整合
    	1,管理SessionFactory实例(只需要一个)
    	2,声明式事务管理
    
    Spring
    	IOC	管理对象...
    	AOP	事务管理...
