java web框架 spring+spring mvc+mybatis/hibernate项目总结(1)

本人Android移动开发4年经验，因为最近一段时间想着换工作，但发现移动开发现如今的大环境不是太好，于是想着转其他开发岗位，由于自己以前学过后台开发，也曾经在公司维护过一段时间的后台代码，现如今想转回java web开发于是写了下面的文章将已经java web的项目复习一下希望能对找java开发的工作有所帮助。

为了能快速的将现阶段热门的java框架上手买了一本Spring+Mybatis企业级应用实战。我将此项目分成四个分支提交到了我的github上,

四个分支分别为:

(1)master:原项目,spring+mybatis+mysql注解方式

(2)hrm_xml:spring+mybatis+mysql xml配置方式

(3)hrm_oracle:spring+mybatis+oracle xml配置方式

(4)hrm_oracle:spring+hibernate+oracle 注解方式

github地址:https://github.com/jessear/hrm

下面我将对四个分支逐一来进行讲解

spring+mybatis+mysql注解方式:
