1.整合关键点
Spring：负责对象的创建、维护、管理及对象依赖资源的注入
SpringMVC：负责请求的处理相当于(Servlet)
MyBatis：负责与数据库进行交互
2.整合步骤
2.1.在pom.xml文件中导入依赖
mybatis、spring-webmvc、mybatis-spring、bonecp数据源、mysql、spring-jdbc、log4j、jstl
2.2.编写配置文件
spring-config.xml、 springmvc-config.xml 、mybatis-config.xml、log4j.properties spring-config.xml内容： 数据源|sqlSessionFactory|映射器|扫描支持注解的Bean|事务管理器|基于注解事务 springmvc-config.xml：组件扫描(controller)|注解驱动|视图解析器|文件上传等 mybatis-config.xml内容：日志记录工具|批量取别名|批量加载映射文件
2.3.定义项目结构和代码
com.ssm.entity|com.ssm.dao|com.ssm.service| com.ssm.service.impl|com.ssm.controller
2.4.配这web.xml
加载spring-config.xml|springmvc-config.xml|中文乱码
2.5.测试功能
3.整合实现——查询单个和所有
3.1.导入依赖

return new ModelAndView("forward:stulist.do","msg","update success!");
}
return null;
}首页页面消息展示：对应index.jsp页面
<span style="color:red">${msg==null?'':msg}</span>7.增加功能
7.1.增加超链接
<p><a href="toAddPage.do">增加学生</a></p>7.2.数据接口
@Insert("insert into student(sname,sex,age,phone,address) values(#{sname},#{sex},#
{age},#{phone},#{address})")
int addStu(Student stu); //增加学生7.3.业务接口
int addStu(Student stu); //增加学生7.4.业务实现
@Override
public int addStu(Student stu) {
return stuMapper.addStu(stu);
}7.5.控制层代码
//增加学生
@RequestMapping("/addStu.do")
public ModelAndView addStu(Student stu){

if(num>0){
return new ModelAndView("forward:stulist.do","msg","add success!");
}
return null;
}7.6.页面消息展示
对应首页index.jsp
<span style="color:red">${msg==null?'':msg}</span>
