• 搭建Jquery+SpringMVC+Spring+Hibernate+MySQL平台


    一. 开发环境

      1. 点击此查看并下载需要的 Eclipse IDE for Java EE Developers 开发工具,依赖于java,推荐选用32位

        2. 点击此查看并下载需要的 MySQL Server 数据库,推荐选用32位

      3. 点击此找到并下载  Java SE Development Kit 6u45,有些dll只能在32位上运行,推荐选用32位

      4. 点击此找到并下载  apache-tomcat-6.0.48.zip,兼容32位和64位版本

      5. 点击此下载 ims 工程文件

      6. 点击此查看 maven 私服搭建指南

      7. 点击此查看 maven 上传第三方jar

    二. 工程搭建

      1. Eclipse --> File --> New --> Dynamic Web Project --> 输入工程名 ims --> Next -->

        修改 Default output folder 为:WebContent/WEB-INF/classes --> Finish

      2. 将下载的工程文件按目录复制到 ims 工程中

      注:ims全称:information management system

    三. 工程目录结构介绍

      注:以下的xxx均表示子项目名称,如:

        子项目 sys 全称:system,基础信息、权限管理系统

        子项目 mms 全称:material management system,材料管理系统

        子项目 iot 全称:Internet of things,物联网系统
