框架介紹

Spring
SpringMVC
MyBatis
easyUI

大家應該也都有所瞭解，概念性的東西就不寫了，有萬能的百度。

開發環境

JDK 1.7
Mysql 5.6
IntelliJ IDEA 16
tomcat 7

以上為本地的構建環境，當然，如果開發環境版本或者IDE與以上不同也是可以正常搭建環境的，比如你JDK是1.8啊，IDE用的是eclipse或者Myeclipse都是完全OK的。

專案整合

下圖為專案的目錄結構截圖：

entity包中即為本專案的所有實體類

dao包中為資料層介面
mappers中為資料層介面的sql對映檔案，執行的sql語句是在這些檔案中定義的
admin包中則是控制層程式碼
WebRoot中則是jsp檔案及jar包等檔案。

以上包名都可以按照個人習慣來命名。

第一步，新建一個JavaWeb專案，接下來在src目錄下entity包、mappers包、dao包和service包，並新增配置Spring的檔案applicationContext.xml和mybatis的配置檔案mybatis-config.xml。

applicationContext.xml：
