当今，JavaEE是一个优秀的企业信息化开发平台，由于JavaEE拥有

Today, JavaEE is an excellent enterprise information development platform. Because JavaEE has some good properties including stable performance, very high security and good development, it is widely used in enterprise-level development. This paper is based on the current popular e-commerce system as the project background, and is developed according to the rules of javaEE application software. The system is mainly divided into these four levels, including the model layer, persistence layer, business logic layer and presentation layer, and It integrates the spring, springMvc and myBatis frameworks widely used in enterprises for development. Spring is used for the unified scheduling of the entire system and runs through the layers. The springMvc framework focuses on the implementation of the mvc model. The myBatis framework completes the data mapping and persistence work. The reverse engineering of myBatis greatly facilitates the development of the dao layer. It also facilitates the maintenance of the dao layer of the system. <br>This thesis mainly completed the following tasks:

当今，JavaEE是一个优秀的企业信息化开发平台，由于JavaEE拥有一些很好的性质包括稳定的性能、非常高的安全性和良好的开发性因此被广泛运用于企业级开发。这篇论文基于当前比较流行的电商系统为项目背景，根据javaEE应用软件规则进行的开发，将系统主要划分为这四个层次,其中包括模型层，持久层，业务逻辑层和表现层，并整合了目前在企业中广泛运用的spring、springMvc和myBatis框架进行开发。Spring用于整个系统的统一调度，贯穿于各层之间，springMvc框架着重于mvc模式的实现，myBatis框架完成数据的映射和持久化工作，myBatis的逆向工程极大的方便了dao层的开发，也方便了系统dao层的维护。<br>本论文主要完成了以下的任务：
