框架介紹
- Spring
- SpringMVC
- MyBatis
- easyUI
大家應該也都有所了解,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。
項目整合
下圖為項目的目錄結構截圖:
- entity包中即為本項目的所有實體類
- dao包中為數據層接口
- mappers中為數據層接口的sql映射文件,運行的sql語句是在這些文件中定義的
- admin包中則是控制層代碼
- WebRoot中則是jsp文件及jar包等文件。
以上包名都可以按照個人習慣來命名。
第一步,新建一個JavaWeb項目,接下來在src目錄下entity包、mappers包、dao包和service包,並新增配置Spring的文件applicationContext.xml和mybatis的配置文件mybatis-config.xml。
applicationContext.xml:

結語
整合過程中需要注意的點:
- 項目編碼設置正確
- jar包要齊全
- mysql要能正常登錄
當然,也可以直接導入源碼, 點擊這里下載代碼。
