1.导入jar包

2.创建mybatis核心配置文件SqlMapConfig.xml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>	
   <mappers>
   		<mapper resource="com/lq/model/User.xml"/>
   </mappers>   
</configuration>

3.创建spring配置文件 applicationContext.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:tx="http://www.springframework.org/schema/tx"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
    			http://www.springframework.org/schema/beans/spring-beans-3.2.xsd  
                http://www.springframework.org/schema/context  
                http://www.springframework.org/schema/context/spring-context-3.2.xsd  
                http://www.springframework.org/schema/tx   
                http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
                http://www.springframework.org/schema/aop
                http://www.springframework.org/schema/aop/spring-aop.xsd
                ">

	<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName">
			<value>com.mysql.jdbc.Driver</value>
		</property>
		<property name="url">
			<value>jdbc:mysql://localhost:3306/test</value>
		</property>
		<property name="username">
			<value>root</value>
		</property>
		<property name="password">
			<value>root</value>
		</property>
	</bean>
	<!-- 配置事务管理 -->
	<bean id="txManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>

	<!-- 利用AOP,实现对Service的声明式事务管理 -->
	<!-- 通知 -->
	<tx:advice id="txAdvice" transaction-manager="txManager">
		<tx:attributes>
			<tx:method name="*" rollback-for="java.lang.Exception" />
		</tx:attributes>
	</tx:advice>

	<aop:config>
		<!-- 切入点 -->
		<aop:pointcut id="servicepointcut" expression="execution(* com.lq.dao.*.*(..))" />
		<!-- 把切入点和通知连接起来 -->
		<aop:advisor advice-ref="txAdvice" pointcut-ref="servicepointcut" />
	</aop:config>

	<!-- 配置sqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- mybatis配置文件路径 -->
		<property name="configLocation" value="classpath:config/SqlMapConfig.xml" />
		<property name="dataSource" ref="dataSource" />
	</bean>

	<!-- 配置sqlsession 产生这个实例就是通过 sqlsessionTemplate来实现的 -->
	<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
		<constructor-arg index="0">
			<ref bean="sqlSessionFactory" />
		</constructor-arg>
	</bean>
</beans>

4.创建Springmvc配置文件 spring-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"  
    xmlns:mvc="http://www.springframework.org/schema/mvc"   
    xsi:schemaLocation="  
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd  
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd  
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd ">

    <!-- 设置包扫描路径（指定包下面的类含有@Controller @Service @Repository 会被注册为bean） -->  
    <context:component-scan  base-package="com.lq"></context:component-scan>
    <!-- 启用注解功能 -->
    <mvc:annotation-driven/>
    
    <!--  视图解析器 -->  
    <bean id="viewResolver"  class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
	    <property name="prefix" value="/WEB-INF/view/"> </property>  
	    <property name="suffix"  value=".jsp"></property>  
    </bean>  
  
</beans>

5.在web.xml中配置spring监听器、前端控制器,并配置需要启动就要加载的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	id="WebApp_ID" version="3.0">
	<display-name>ssm2</display-name>
	<!-- 加载spring容器配置 启动Web容器时，自动装配applicationContext.xml的配置信息 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 设置Spring容器加载配置文件的路径 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>    
         classpath:config/applicationContext.xml    
       </param-value>
	</context-param>
	<!-- 字符编码过滤器 -->
	<filter>
		<filter-name>encodingFilter</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>encodingFilter</filter-name>
		<url-pattern>*.do</url-pattern>
	</filter-mapping>
	<!-- 前端控制器 -->
	<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:config/springmvc-servlet.xml
            </param-value>
		</init-param>
		<!-- 这个配置文件在容器启动的时候 就加载 -->
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<!-- 拦截请求 -->
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>

	<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>
</web-app>

6.log4j支持

#log4j
#指定日志级别和日志输出的目的地
log4j.rootLogger=DEBUG, console
#ConsoleAppender说明日志输出的目的地是控制台
log4j.appender.console=org.apache.log4j.ConsoleAppender
#指定输出的样式的类为PatternLayout（灵活）
log4j.appender.console.layout=org.apache.log4j.PatternLayout
#为PatternLayout配置一个灵活的样式 %d(日志输出的时间) %p(日志的级别)  %m(输出代码中指定的消息) %n(回车换行符)
log4j.appender.console.layout.ConversionPattern=%d - %p - %m%n
#   SqlMap   logging   configuration...
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
log4j.logger.java.sql.ResultSet=DEBUG

7.创建DAO层

@Repository("userDao")
public class UserDao implements IUserDao {
	/**
	 * 自动注入sqlSession
	 */
	@Autowired
	private SqlSessionTemplate sqlSession;

	public SqlSessionTemplate getSqlSession() {
		return sqlSession;
	}

	public void setSqlSession(SqlSessionTemplate sqlSession) {
		this.sqlSession = sqlSession;
	}
	
}

8.创建业务逻辑层

@Service("userService")
public class UserService implements IUserService {
	/**
	 *自动注入dao层
	 */
	@Autowired
	private IUserDao userDao;

	public IUserDao getUserDao() {
		return userDao;
	}

	public void setUserDao(IUserDao userDao) {
		this.userDao = userDao;
	}
}

9.创建控制层

@Controller
@RequestMapping("/user")
public class UserController {
	@Autowired
	private IUserService userService;

	public IUserService getUserService() {
		return userService;
	}

	public void setUserService(IUserService userService) {
		this.userService = userService;
	}
	
}
