讲师:宋江

一.项目背景

项目特色

1.该管理平台采用了当前最流行的S2SH进行总体架构，充分利用框架整合后的各种特性，并加入maven进行项目的分模块开发，有效进行项目管理。

2.采用了BRAC认证模型，有效进行用户权限管理，同时加入当前流行的Shiro安全框架，从而使得系统更加安全可靠。

3.结合Sybase引入数据库设计相关理念，及打断设计理论。

4.使用Apache POI实现海量数据导出。

5.采用跳跃查询相关思想，并结合数据搬家的操作手段，从而有效提高了系统性能。

6.利用CodeMachine实现代码自动生成技术，从而解放程序员的部分编码工作。

7.使用amChart+Flash形成各种统计图形，从而为高层提供决策支撑。

8.引入JavaMail邮件机制，并实现Spring与JavaMail整合开发，实现邮件发送中加入附件。

9.加入了Quartz实现的定时任务调度，并结合Spring整合好的Mail，很好的解决了报表向

公司高层的定时发送功能。

10.引入WebService的CXF开发方式，并与Spring结合，从而很好的解决了电子报运问题

二.界面原型法

原型它的目的，它给客户提前看未来的系统长什么样子。客户就能有一个直观的印象。

界面原型法，在实际需求调研阶段用的非常多。和用户谈需求并进行记录，跟web前端页面工程师沟通，让其设计出一套相关的页面原型，再拿过去与用户再次进行沟通，并修改进行记录，再回来进行页面的修改，如果确认，将来的页面就基本不再改动。

目的就是在最短的时间里，得到用户最真实的需求。

三.UML的UseCase图

1.获取需求是专业的

2.usecase就是用例图，它是专门用于描述需求的

3.uml代表统一建模语言

它包含很多图：用例图，类图，状态图，序列图…….

4.软件：

Rose, pd(powerDesigner 可以画uml图也可以进行数据库设计)，Visio

OOP 面向对象编程

OOM 面向对象建模

OOD 面向对象设计

OOA 面向对象分析 (analysis)

工作空间—新增----oom----use case diagram

需求描述：

四. 系统功能模块结构图

系统功能结构图

它的作用？

1.功能模块一目了然

2.便于分工

3.便于进行项目报价

五．系统框架

如果自己搭建框架：

如果使用的别人的框架：

1.首先看jar包

2.画图

3.确定哪些技术需要学习。

搭建maven结构的过程：

1. 创建父工程

引入这个pom.xml,如果没有本地的更新，也要先进行本地仓库的更新

Pom

2. 创建子模块

BaseDao

public
interface BaseDao {

    //查询所有，带条件查询
    public <T> List<T> find(String
hql, Class<T> entityClass, Object[]
params);
    //获取一条记录
    public <T> T get(Class<T>
entityClass, Serializable
id);
    //分页查询，将数据封装到一个page分页工具类对象
    public <T> Page<T> findPage(String
hql, Page<T> page, Class<T>
entityClass, Object[]
params);

    //新增和修改保存
    public <T>
void saveOrUpdate(T
entity);
    //批量新增和修改保存
    public <T>
void saveOrUpdateAll(Collection<T>
entitys);

    //单条删除，按id
    public <T>
void deleteById(Class<T>
entityClass, Serializable id);
    //批量删除
    public <T>
void delete(Class<T>
entityClass, Serializable[] ids);

}

六.面试

1.请写出hibernate中主键生成策略常用6种方式
native,uuid,increment,identity,sequence,assigned

2.Byte/Short/int/char/varchar运行速度及区别
运行速度: Byte/Short/int/char/varchar 由快到慢
Char是一个固定长度，这样可能导致空间浪费，但反应快速比varchar快。
Varchar可以做到空间最省，但会多长度比较的过程，所以很浪费时间。

3.面试
请参考数据库表结构写出PO类及映射文件
PO类：

映射文件

面试：PO类的定义规范
