SSM框架搭建实例

SSM框架搭建简单实例 - 搭建步骤

---

需求分析：

   实现用户表信息的增删改查

---

1. 开发环境

• 环境  ： JDK  1.8         
• 软件 ： myeclipse       
• 数据库 ： MySql

2. 创建数据库

• 数据库名称：ssm           
• 字符集：UTF-8         
• 表 ： user

3. 工程搭建

•   工程使用Springmvc、spring、mybatis框架整合完成。
• 项目完整目录截图
• 

4. 创建web工程

• 准备需要的jar包

1. spring（包括springmvc）
2. mybatis
3. mybatis-spring整合包
4. 数据库驱动
5. 第三方连接池。
6. Json依赖包（springmvc 自带，可不加）

• web.xml  文件

       需要配置的有  ： Spring监听器， SpringMVC 核心前端控制器， 字符集过滤器

  SSM
  
    index.jsp
  
  
  
  
  	contextConfigLocation
  	classpath:applicationContext.xml
  
  
  	org.springframework.web.context.ContextLoaderListener
  
  
  
  
  	springmvcDispatcherServlet
  	org.springframework.web.servlet.DispatcherServlet
  	
  		contextConfigLocation
  		classpath:springmvc.xml
  	
  
  
  	springmvcDispatcherServlet
  	*.action
  
  
  
  
  	characterEncodingFilter
  	org.springframework.web.filter.CharacterEncodingFilter
  	
  		encoding
  		UTF-8
  	
  
  
  	characterEncodingFilter
  	/*
  
  
  

三个框架的配置文件，统一放在 conf 文件夹下（source folder 文件夹）

• applicationContext.xml    【Spring 的 配置文件】

• springmvc.xml    【SpringMVC 的 配置文件】

• SqlMapConfig.xml    【MyBatis 的 配置文件】

• db.properties        【数据库配置文件】

driverClass=com.mysql.jdbc.Driver
url=jdbc\:mysql\://localhost\:3306/ssm
user=root
pwd=root

• log4j.properties    【日志配置文件】
