说明：  技术要点： 1 此系统采用了目前最流行的ssm框架,其中的spingMVC框架相对于struts2框架更灵活，更安全。 2 本项目springMVC框架采用了注解映射器，使用了RESTful风格的url对系统发起http请求,开发更灵活。 3 同时使用了了hibernate提供的校验框架，对客户端数据进行校验！ 4 Mybati数据库DAO层采用的是Mapper代理开发方法，输入映射采用的是POJO包装类型实现,输出映射采用了resultMap类型，实现了数据库多对一映射。 5 spring容器内部使用拦截器，以Spring AOP的方式实现事务控制管理。(Technical points: 1. This system adopts the most popular SSM framework at present. The sping MVC framework is more flexible and safer than the struts 2 framework. 2 The spring MVC framework of this project adopts annotation mapper, and uses RESTful style URL to initiate HTTP requests to the system, which makes the development more flexible. 3 At the same time, the verification framework provided by hibernate is used to verify the client data.)
