框架介绍

  • Spring
  • SpringMVC
  • MyBatis
  • easyUI

大家应该也都有所了解,概念性的东西就不写了,有万能的百度。

开发环境

  • JDK 1.7
  • Mysql 5.6
  • IntelliJ IDEA 16
  • tomcat 7

以上为本地的构建环境,当然,如果开发环境版本或者IDE与以上不同也是可以正常搭建环境的,比如你JDK是1.8啊,IDE用的是eclipse或者Myeclipse都是完全OK的。

项目整合

下图为项目的目录结构截图:

  • entity包中即为本项目的所有实体类
  • dao包中为数据层接口
  • mappers中为数据层接口的sql映射文件,运行的sql语句是在这些文件中定义的
  • admin包中则是控制层代码
  • WebRoot中则是jsp文件及jar包等文件。

以上包名都可以按照个人习惯来命名。

第一步,新建一个JavaWeb项目,接下来在src目录下entity包、mappers包、dao包和service包,并新增配置Spring的文件applicationContext.xml和mybatis的配置文件mybatis-config.xml。

applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

结语

整合过程中需要注意的点:

  • 项目编码设置正确
  • jar包要齐全
  • mysql要能正常登录

当然,也可以直接导入源码, 点击这里下载代码。
