调查管理系统（1）

调研系统，调查系统（调查页面，1.页标题，2.常规页，非常规页，高级页3.问题（问题类型：非矩阵，矩阵），答案） 4.（动态表单，如何统计数据 ）5. 统计生成报表文件，分析     6.对可见的调查参加调查 7.用户角色

struts2开发  servlet--ActionServlet

开发web程序的框架,基于filter--StrutsPrepareAndExecuteFilter.
耦合度低:
1.原生servlet API
2.我们自己的类和struts2的api.
3.拦截器
分离关注:拦截器.
action:原型,有状态.独占,线程安全.相对的性能下降

hibernate持久化层

spring 业务层管理bean(默认是单例的，最好改为多例)

synchorized:锁
threadlocal:线程本地化.数据安全.

m:model,模型,携带数据.
v:view,显示层
c:controller.


单例:
多例:pool,池化技术.
原型:原始模型.
scope:singleton|prototype|request|session|global session


hibernate:
持久化技术,封装数据的访问细节(sql + ??),体现oop.
轻量级jdbc


spring:
业务层框架,管理bean的容器.
ioc:inverse of controller,获得依赖对象方式.
aop:面向切面编程,aspect oriented program
通知:前置 后置 环绕 异常 引入,
使用代理：1-jdk动态代理(接口代理) 2-cglib代理(final)


搭建项目:
1.创建web项目
2.引入类库
