SSM整合步骤

SSM- CRUD

SSM : SpringMVC+Spring+Mybatis

Create (新建) +Retrieve (查询) +Update(更新)+Delete(删除)

 

 功能点

1：分页

2：数据校验：JQuery前端校验+JSR后端校验。

3：ajax

4：Rest风格URL：使用HTTP协议请求方式的动词，来表示对对资源的操作：GET(查询)、POST(新增)、PUT(修改)、DELETE(删除)。

 

技术点

1：基础框架-SSM (SpringMVC+Spring+MyBatis)

2：数据库-MySQL 5

3：前端框架-bootstrap快速搭建简洁美观的前端界面。

4：项目的依赖管理-Maven。

5：分页插件-pagehelper

6：逆向工程-MyBatis Generator

 

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
• 其它包[  jstl , servlet-api ,  junit ]
  

maven 配置文件增加配置

 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

 web.xml

        class>org.springframework.web.servlet.DispatcherServletclass>
        1
    

    
    
        dispatcherServlet
        /
    

    
    
        CharacterEncodingFilter
        class>org.springframework.web.filter.CharacterEncodingFilterclass>
        
            encoding
            utf-8
        
        
            forceRequestEncoding
            true
        
        
            forceResponseEncoding
            true
        
    
    
    
        CharacterEncodingFilter
        /*
