第一步   在Maven中添加spring springMVC  Mybatis所依赖的jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

</project>

第二步   添加jar包后，去创建数据库表对应的实体类，并且创建dao（注意：这里的dao是接口），新建mapper，为接口做个映射

   与数据库对应的实体类

package com.hzit.entity;

public class Supply {
	private String gid1;
	private String gongyingshangname1; 
	private String jianjie1; 
	private String lianxiren1; 
	private String dianhua1;
	private String adress1;
	private String chuanzhen1; 
	private String createtime1;
	
	
	public String getGid1() {
		return gid1;
	}
	public void setGid1(String gid1) {
		this.gid1 = gid1;
	}
	public String getGongyingshangname1() {
		return gongyingshangname1;
	}
	public void setGongyingshangname1(String gongyingshangname1) {
		this.gongyingshangname1 = gongyingshangname1;
	}
	public String getJianjie1() {
		return jianjie1;
	}
	public void setJianjie1(String jianjie1) {
		this.jianjie1 = jianjie1;
	}
	public String getLianxiren1() {
		return lianxiren1;
	}
	public void setLianxiren1(String lianxiren1) {
		this.lianxiren1 = lianxiren1;
	}
	public String getDianhua1() {
		return dianhua1;
	}
	public void setDianhua1(String dianhua1) {
		this.dianhua1 = dianhua1;
	}
	public String getAdress1() {
		return adress1;
	}
	public void setAdress1(String adress1) {
		this.adress1 = adress1;
	}
	public String getChuanzhen1() {
		return chuanzhen1;
	}
	public void setChuanzhen1(String chuanzhen1) {
		this.chuanzhen1 = chuanzhen1;
	}
	public String getCreatetime1() {
		return createtime1;
	}
	public void setCreatetime1(String createtime1) {
		this.createtime1 = createtime1;
	}
	
	
}

dao类,也就是接口

package com.hzit.dao;

import java.util.List;

import org.springframework.stereotype.Repository;

import com.hzit.entity.Supply;
@Repository("supplyDao")
public interface SupplyDao {
	public List<Supply> getAll();
}

映射文件mapper，注意：mapper的namespace要与上面的接口的类名一致，对应select的id要与接口中的方法名一致

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.hzit.dao.SupplyDao">
	<resultMap type="com.hzit.entity.Supply" id="BaseResultMap">
	<!-- resultMap中column为数据库的列，property为实体类中的属性 -->
			<id column="gongyingshangname" jdbcType="VARCHAR" property="gongyingshangname1"/>	
			<result column="gid" jdbcType="VARCHAR" property="gid1"/>
			<result column="jianjie" jdbcType="VARCHAR" property="jianjie1"/>
			<result column="adress" jdbcType="VARCHAR" property="adress1"/>
			<result column="chuanzhen" jdbcType="VARCHAR" property="chuanzhen1"/>
			<result column="createtime" jdbcType="DATE" property="createtime1"/>
	</resultMap>
	
	<select id="getAll" resultMap="BaseResultMap">
		select * from gongyingshang
	</select> 


</mapper>

第三步 创建jdbc.properties、spring-mybatis.xml、springMVC-servlet.xml文件，并且配置web.xml文件

            1.jdbc.properties文件用来存放连接数据库的4个信息，驱动、地址、连接账号、连接密码

            2.spring-mybatis.xml用来整合spring和mybatis框架

            3.springMVC-servlet.xml是spring框架的一部分，主要负责配置视图解析器等功能

    jdbc.properties文件

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/chaoshi
username=root
password=root

 spring-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>

        http://www.springframework.org/schema/mvc/spring-mvc.xsd">       
        
         <!-- 引入配置文件 -->

	<!-- DataSource -->

		<property name="username" value="${username}"></property>

	</bean>
	
	<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->  
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
        <property name="dataSource" ref="dataSource" /> 
        <property name="typeAliasesPackage" value="com.hzit.entity" /> 
        <!-- 自动扫描mapping.xml文件 -->  
        <property name="mapperLocations" value="classpath:com/hzit/mapper/*.xml"></property>  
    </bean> 
    
	<!-- 接口所在包名，Spring会自动查找其下的类 -->  
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
        <property name="basePackage" value="com.hzit.dao" />  
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>  
    </bean>    
        
        
        </beans>

springMVC-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="

        <!-- 开启扫描注解 -->

        <context:component-scan base-package="com.hzit"/> 
        <mvc:annotation-driven enable-matrix-variables="true"></mvc:annotation-driven>
           <!-- 支持上传文件 -->  
       <!-- <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>  -->   
	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

   		 <property name="defaultEncoding" value="UTF-8"/>
    </bean>
	<!-- 配置视图解析器（ViewResolver） -->
	<bean id="viewResolver"

		<property name="suffix" value=".jsp" />
	</bean>  
        
        
        
        </beans>

配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"  
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">  
  <display-name>Archetype Created Web Application</display-name>
  <!-- 处理乱码 -->
	<filter>
		<filter-name>characterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:spring-mybatis.xml</param-value>
  </context-param> 
  
  <listener>
 	 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <servlet>
  	<servlet-name>SpringMVC</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:springMVC-servlet.xml</param-value>
  	</init-param>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>SpringMVC</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>
  
  
</web-app>

第四步  创建业务层、控制层和页面来显示数据（使用注解来进行依赖注入）

业务层依赖于dao层，需要通过注解来进行注入dao

package com.hzit.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;

import com.hzit.dao.SupplyDao;
import com.hzit.entity.Supply;

@Service("supplyService")
public class SupplyService {
	
	@Autowired
	@Qualifier("supplyDao")
	private SupplyDao dao;
	
	public List<Supply> queryAll(){
		return dao.getAll();
	}
}

控制层依赖于业务层，需要对控制层进行注入业务层

package com.hzit.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

import com.hzit.entity.Supply;
import com.hzit.service.SupplyService;

@Controller
public class SupplyController {
	
	@Autowired
	private SupplyService supplyService;
	
	@RequestMapping("/queryAll")
	public String get(ModelMap model) {
		List<Supply> list = supplyService.queryAll();
		model.put("list", list);
		return "index";
	}
	

}

jsp页面做显示层

<%@ page language="java" isELIgnored="false" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
	<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
	
	<body>
	${list }
	
	</body>
</html>

在地址栏输入127.0.0.1:8080/bookTest/queryAll,出现页面上有数据，就证明ssm框架整合完成，后台到前端页已经打通，这是我的例子中页面上的数据

[com.hzit.entity.Supply@436f7803, com.hzit.entity.Supply@7a53b6d6, com.hzit.entity.Supply@24e80495, com.hzit.entity.Supply@52f9a8df, com.hzit.entity.Supply@6aee6de3, com.hzit.entity.Supply@d6c936e, com.hzit.entity.Supply@69c4e2fa, com.hzit.entity.Supply@76e4104d, com.hzit.entity.Supply@6ffcea07, com.hzit.entity.Supply@6e2e375, com.hzit.entity.Supply@48ff0261, com.hzit.entity.Supply@1ecf054b, com.hzit.entity.Supply@166b6847, com.hzit.entity.Supply@783c8b4, com.hzit.entity.Supply@375f3e2f]
