整合spring+springMVC+mybatis

1、导入相关jar包

2、编写配置文件

（1）web.xml——配置spring，配置spring mvc

<?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_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>ssmtest</display-name>
  
  <!-- Spring的配置文件 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:spring-context.xml</param-value>
  </context-param>
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!-- SpringMVC的配置文件 -->
  <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:spring-mvc.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>springMVC</servlet-name>
  	<url-pattern>*.asp</url-pattern>
  </servlet-mapping>
  
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
</web-app>

（2）spring-mvc.xml如果需要其他处理需要填写相关配置

<?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/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
		http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
		http://www.springframework.org/schema/context 
		http://www.springframework.org/schema/context/spring-context-4.2.xsd">
		
		<!-- 扫描该包下的注解 -->
		<context:component-scan base-package="com.ssmtest.web"></context:component-scan>
</beans>

（3）spring-context.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:p="http://www.springframework.org/schema/p"
	xmlns:c="http://www.springframework.org/schema/c"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-4.2.xsd

        http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
        http://www.springframework.org/schema/security
        http://www.springframework.org/schema/security/spring-security-4.2.xsd 
        http://www.springframework.org/schema/cache 
        http://www.springframework.org/schema/cache/spring-cache.xsd">
        
        <!-- 读取属性文件  -->
       <bean class=" org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
       		<property name="location" value="classpath:jdbc.properties" ></property>
       </bean> 
        <!-- 配置dataSource -->
       <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
       		<property name="username" value="${jdbc.username}" />
			<property name="password" value="${jdbc.password}" />
			<property name="driverClassName" value="${jdbc.driverClassName}" />
			<property name="url" value="${jdbc.url}" />
       </bean>
       
       <!-- 配置工厂 --> 
       <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
       		<property name="dataSource" ref="dataSource"/>
       		<property name="configLocation" value="classpath:spring-mybatis.xml"></property>
       </bean>
       
       <!-- 配置声明式事务 -->
       <!-- 事务管理器 -->
       <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
       		<property name="dataSource" ref="dataSource"></property>
       </bean>
       <tx:advice id="txAdvice" transaction-manager="txManager">
       		<tx:attributes>
       			<tx:method name="save" propagation="REQUIRED"/>
       			<tx:method name="get" read-only="true"/>
       			<tx:method name="*" propagation="REQUIRED"/>
       		</tx:attributes>
       </tx:advice>
       
       <aop:config>
       		<aop:pointcut expression="execution(* com.ssmtest.service.impl.*.*(..))" id="pointcut"/>
       		<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
       </aop:config>
       
       <!-- 配置注解 -->
       <context:component-scan base-package="com.ssmtest"/>
</beans>

（4）spring-mybatis.xml

<?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>
		<package name="com.ssmtest.entity"/>
	</typeAliases>
	<mappers>
		<!-- 所有mapper文件 -->
		<mapper resource="com/ssmtest/entity/mapper/UserTestMapper.xml" />
	</mappers>
	
</configuration>

3、编码测试
