软件架构
软件架构说明
HTML+Css+JavaScript+JQuery+Java+Oracle
- resource里面是jdbc.properties，连接的是Oracle数据库，xe版
- src分controller层和service层
- controller层分为四个包
- controller层
- fileservlet包是文件的上传
- 里面uploadservlet
- filter包是过滤器
- EncodingFilter
- 这个专门过滤中文编码，访问乱码
- LoginAutoFilter
- 这个专门过滤登录信息，可以查看是否登陆过，如果登陆过可以直接访问其他资源
- 如果未登录，强制跳转到登录界面
- LoginFilter
- 看是不是第一次登陆，通过cookie判断
- listener包
- VisitListener主要用来统计访问量
- utils包
- 里面的ServletProcessing主要用来将字符串的内容规范一下，去掉引号
- webservlet包
- 实现一些增删改查给前端数据
- service层里面主要是JDBC
- dao，service，entity，utils
- dao里面是一些增删改查
- service是检验增删改查是否成功
- entity是实体类
- orm思想对应表的实体类，还有一些需要临时查询创建的实体类
- utils
- 里面是数据库连接需要的获取连接，以及德鲁伊连接池
