关于SSM的整合  
1、导入相关的jar包[需要的话可以下载最基础的jar包 提取码iecv][jar_ _iecv]

2、导入数据源文件以及mybatis的配置文件

//数据源文件
    jdbc.driverClassName=com.mysql.jdbc.Driver
    jdbc.url=jdbc\:mysql\://localhost\:3306/ssm?useUnicode\=true&characterEncoding\=UTF-8
    jdbc.username=root
    jdbc.password=root

//mybatis配置文件
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
    	<typeAliases>
    		<typeAlias type="com.ssm.bean.Customer" alias="Customer"/>
    	</typeAliases>
    	<mappers>
    		<mapper resource="com/ssm/bean/customerMapper.xml"/>
    	</mappers>
    </configuration>

3、配置spring的xml

//spring的xml配置
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:context="http://www.springframework.org/schema/context"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns:aop="http://www.springframework.org/schema/aop"
    	xmlns:tx="http://www.springframework.org/schema/tx"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans
    	http://www.springframework.org/schema/beans/spring-beans.xsd
    	http://www.springframework.org/schema/context
    	http://www.springframework.org/schema/context/spring-context-4.3.xsd
    	http://www.springframework.org/schema/aop
    	http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
    	http://www.springframework.org/schema/tx
    	http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
    	
      
       
       <context:property-placeholder location="classpath:db.properties" />
         
        <context:component-scan base-package="com.ssm.service.impl"></context:component-scan>
      
       
       
       
    	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    		destroy-method="close">
            <property name="driverClassName" value="${jdbc.driverClassName}" />
    		<property name="url" value="${jdbc.url}" />
    		<property name="username" value="${jdbc.username}" />
    		<property name="password" value="${jdbc.password}" />
    		<property name="maxActive" value="10" />
    		<property name="maxIdle" value="5" />
         </bean>
         
         
    	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    		
    		<property name="configLocation" value="classpath:conf.xml" />
    		
    		<property name="dataSource" ref="dataSource" />
    	</bean>
    	
    	
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    	
    	<property name="basePackage" value="com.ssm.dao" />
    </bean>
     
     
    	<bean id="myHibTransactionManager"
    		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    		<property name="dataSource" ref="dataSource"></property>
    	</bean>
    	
    	 <tx:annotation-driven transaction-manager="myHibTransactionManager"/>
    	 </bean>

5、spring-mvc的配置

//配置spring-mvc
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    	xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans
    	http://www.springframework.org/schema/beans/spring-beans.xsd
    	http://www.springframework.org/schema/context
    	http://www.springframework.org/schema/context/spring-context-4.3.xsd
    	http://www.springframework.org/schema/aop
    	http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
    	http://www.springframework.org/schema/tx
    	http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
    	http://www.springframework.org/schema/mvc
    	http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
    	">
    	
    	<context:component-scan base-package="com.ssm.controller"></context:component-scan>
    	
    	<mvc:annotation-driven></mvc:annotation-driven>
    	
    	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp">
    	</bean>
    </beans>

6、web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
      <display-name>SSM01</display-name>
      <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
      </welcome-file-list>
        <listener>
    		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    	</listener>
    	  <context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>/WEB-INF/applicationContext.xml</param-value>
    	</context-param>
      <servlet>
            <servlet-name>springmvc</servlet-name>
            <servlet-class>
                org.springframework.web.servlet.DispatcherServlet
            </servlet-class>
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>/WEB-INF/applicationContext-mvc.xml</param-value>
            </init-param>
        </servlet>
        <servlet-mapping>
            <servlet-name>springmvc</servlet-name>
            <url-pattern>*.do</url-pattern>
        </servlet-mapping>
        
        
    	<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>
    
    	</filter>
    
    	<filter-mapping>
    		<filter-name>CharacterEncodingFilter</filter-name>
    		<url-pattern>/*</url-pattern>  </filter-mapping> </web-app>

7、完成上述步骤之后可以在文件的路径下建立一个简单的例子  
bean包下

package com.ssm.bean;
    /** * 客户实体类 * @author *** * */
    public class Customer { 
    	private int id;//客户Id
    	private String userName;//客户名称
    	private String jobs;//客户职位
    	private String phone;//客户电话
    	public int getId() { 
    		return id;
    	}
    	public void setId(int id) { 
    		this.id = id;
    	}
    	public String getUserName() { 
    		return userName;
    	}
    	public void setUserName(String userName) { 
    		this.userName = userName;
    	}
    	public String getJobs() { 
    		return jobs;
    	}
    	public void setJobs(String jobs) { 
    		this.jobs = jobs;
    	}
    	public String getPhone() { 
    		return phone;
    	}
    	public void setPhone(String phone) { 
    		this.phone = phone;
    	}
    	
    	
    }

加入mapper映射文件

//实现简单的查询功能
    <?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.ssm.dao.ICustomerDao">
    	<select id="findCustomerById" parameterType="int" resultType="Customer">
    		select * from customer where id=#{ id}
    	</select>
    </mapper>

8、创建接口与映射文件对应（前面的xml中定义了mapper代理的形式）  
dao包下：

package com.ssm.dao;
    
    import com.ssm.bean.Customer;
    
    public interface ICustomerDao { 
    	/** * 根据客户id查询信息 * @param id * @return */
    	public Customer findCustomerById(int id);
    }

9、创建一个service来调用上面的接口

package com.ssm.service;
    
    import com.ssm.bean.Customer;
    
    public interface ICustomerService { 
    	/** * 根据客户id查询信息 * @param id * @return */
    	public Customer findCustomerById(int id);
    }

实现接口

package com.ssm.service.impl;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import com.ssm.bean.Customer;
    import com.ssm.dao.ICustomerDao;
    import com.ssm.service.ICustomerService;
    @Service
    public class CustomerService implements ICustomerService { 
    	//实例化dao对象
    	@Autowired
    	ICustomerDao customerDao;
    	@Override
    	public Customer findCustomerById(int id) { 
    		//通过customer对象调用方法进行查询
    		return customerDao.findCustomerById(id);
    	}
    
    }

10、创建一个controller来返回视图，以及调用查询方法

//控制器
    package com.ssm.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import com.ssm.bean.Customer;
    import com.ssm.service.ICustomerService;
    
    @Controller
    public class CustomerController { 
    	@Autowired
    	private ICustomerService customerService;
    	@RequestMapping("/find/{id}")
    	public String find(@PathVariable int id,Model model) { 
    		Customer customer=customerService.findCustomerById(id);
    		model.addAttribute("customer", customer);
    		return "list";
    	}
    }

11、创建一个jsp文件夹并创建视图

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    	<table border="1">
    	<tr>
    		<td>id</td>
    		<td>name</td>
    		<td>jobs</td>
    		<td>tel</td>
    	</tr>
    	<tr>
    		<td>${ customer.id }</td>
    		<td>${ customer.userName}</td>
    		<td>${ customer.jobs }</td>
    		<td>${ customer.phone }</td>
    	</tr>
    	</table>
    </body>
    </html>

12、最终我们就可以测试项目了
