java开发项目流程

1、java开发项目流程Javaweb项目开发流程一、开发准备工作：1、分析需求，根据需求设计数据库 2、选择合适的框架，ssm或者是ssh框架，然后准备相应的加入包 3、根据需求选择合适的前端框架二、在本地搭建环境1、本地环境Jdkl. 7+mysql+tomcat8. 02、前端框架Easyui 和 Bootstrap三、创建web项目（这里以ssh框架为例）1、在工具中创建一个javaweb项目0 New Web ProjectCreate a JavaEE Web ProjectSpecify project name and other detailsProject name: Demo

6、ml4在src目录下创建包,（包名没有限制，这里的包名主要便于区分）Enyity包放实体类ty com.controller0 坦 com.dao；由 com.dao.impD 田 com.entity仞 applicationContext.xml 是I perties HI Iperties % shiro-config.xml lcit；cc k ；lr»cirDao包放实体类的crud操作的接口Daoimp包是放自定义接口的实现类，实现crud操作Contrller包放控制器类，控制页面跳转5、创建数据库自动完成："时卜 下一个标釜，
