SSM整合--CRUD设计步骤

逃离我推掉我的手 2023-06-08 03:12 12阅读 0赞

## 1.技术点 ##

(1) 基础框架-ssm（SpringMVC+Spring+MyBatis） 
    (2) 数据库-MySQL 
    (3) 前端框架-bootstrap快速搭建简洁美观的界面 
    (4) 项目的依赖管理-Maven 
    (5) 分页-pagehelper 插件
    (6) 逆向工程-MyBatis Generator

## 2.基础环境搭建 ##

(1) 创建一个maven工程 
    (2) 引入项目依赖的jar包 
    		• spring 
    		• springmvc 
    		• mybatis 
    		• 数据库连接池，驱动包 
    		• 其他（jstl，servlet-api，junit） 
    (3) 引入bootstrap前端框架 
    (4) 编写ssm整合的关键配置文件 
    		• web.xml
    		• spring
    		• springmvc
    		• mybatis
    		• 使用mybatis的逆向工程生成对应的bean以及mapper
