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

cn.itcast.surveypark.domain

cn.itcast.surveypark.service

cn.itcast.surveypark.service.impl

cn.itcast.surveypark.struts2.action

4.配置文件

[struts2]

1.web.xml

<!-- 配置struts2 filter -->
