项目简介
笔记管理系统,用户可以管理笔记信息,可以查看
其他用户分享的笔记.
主要功能如下
- 用户模块:登录、注册、修改密码、退出
- 笔记本模块:创建、删除、更新、查看
- 笔记模块:创建、删除、更新、查看、转移
- 分享和收藏模块:分享、收藏、查看、搜索分享
- 回收站模块:查看、彻底删除、恢复
- 活动模块:查看活动、参加活动等
项目整体设计
使用的主要技术
jQuery、Ajax、SpringMVC、IOC、AOP、MyBatis
- jQuery:简化前端javascript和ajax编程
- Ajax:页面局部处理;提升用户体验和性能
- SpringMVC:负责接收请求,调用业务组件处理,
将结果生成JSON响应输出
- SpringIOC:负责管理Controller,Service,Dao;维护这些组件对象之间的关系
- MyBatis:负责实现数据库操作,实现Dao
- SpringAOP:负责事务和异常日志功能切入。
(不用修改原有组件代码,就可以追加功能)
项目整体规范
-所有请求采用Ajax方式交互
(使用$.ajax()函数)
-系统页面全部采用HTML
(替代JSP+JSTL+EL)
-所有请求服务器处理完返回的JSON结果格式
如下
{“status”:xx,”msg”:xxx,”data”:xxx}
表现层–》控制层–》业务层–》持久层/数据访问层
HTML(ajax)–>Controller–>Service–>Dao
响应流程
Ajax+SpringMVC+Spring(IOC/AOP)+MyBatis
Ajax–>SpringMVC–>返回JSON结果
JSP响应流程
**请求–>DispatcherServlet–> HandlerMapping–> Controller– 返回ModelAndView/String–> ViewResolver–> JSP –>响应
**
JSON响应流程
请求–>DispatcherServlet–> HandlerMapping–> Controller–> 返回数据对象(int,User,List,Map)–> 引入jackson包,在Controller方法前添加@ResponseBody标记–> JSON响应
搭建环境
创建mysql数据库,名字为:cloud_note,编码格式为utf-8
数据库文件下载地址:
mysql常用数据库语句
- show databases;//查看有哪些库
- use 库名;//使用某个库
- show tables;//查看库里有哪些表
- desc 表名;//查看表结构
- source sql文件;//导入sql文件
导入项目数据库步骤
-set names utf8;
-source D:\cloud_note.sql;
详细的关于mysql的sql可以看我的关于mysql的博客。
创建maven web项目
项目名字为:cloud_note
需要引入的包
- spring-webmvc包
- mybatis包
- dbcp包+MySQL驱动包
- jackson包
- mybatis-spring.jar
- junit包
