MyBatis-SpringMVC整合

1、添加spring相关jar包

2、配置ehcache jar包。

3、添加ehcache mybatis 适配器jar包（在mybatis官网）

4、添加spring mybatis 适配器jar包（在mybatis）官网

5、pom.xml

6、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:context="http://www.springframework.org/schema/context"

    xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring"

    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://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsd

        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <!-- Spring希望管理所有的业务逻辑组件，等。。。 -->

    <context:component-scan base-package="com.atguigu.mybatis">

        <context:exclude-filter type="annotation"

            expression="org.springframework.stereotype.Controller" />

    </context:component-scan>

    <!-- 引入数据库的配置文件 -->

    <context:property-placeholder location="classpath:dbconfig.properties" />

    <!-- Spring用来控制业务逻辑。数据源、事务控制、aop -->

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

        <property name="jdbcUrl" value="${jdbc.url}"></property>

        <property name="driverClass" value="${jdbc.driver}"></property>

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

        <property name="password" value="${jdbc.password}"></property>

    </bean>

    <!-- spring事务管理 -->

    <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

        <property name="dataSource" ref="dataSource"></property>

    </bean>

    <!-- 开启基于注解的事务 -->

    <tx:annotation-driven transaction-manager="dataSourceTransactionManager"/>

    <!--

    整合mybatis

        目的：1、spring管理所有组件。mapper的实现类。

                service==>Dao   @Autowired:自动注入mapper；

            2、spring用来管理事务，spring声明式事务

    -->

    <!--创建出SqlSessionFactory对象  -->

    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="dataSource" ref="dataSource"></property>

        <!-- configLocation指定全局配置文件的位置 -->

        <property name="configLocation" value="classpath:mybatis-config.xml"></property>

        <!--mapperLocations: 指定mapper文件的位置-->

        <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"></property>

    </bean>

    <!--配置一个可以进行批量执行的sqlSession  -->

    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">

        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactoryBean"></constructor-arg>

        <constructor-arg name="executorType" value="BATCH"></constructor-arg>

    </bean>

    <!-- 扫描所有的mapper接口的实现，让这些mapper能够自动注入；

    base-package：指定mapper接口的包名

     -->

    <mybatis-spring:scan base-package="com.atguigu.mybatis.dao"/>

    <!-- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

        <property name="basePackage" value="com.atguigu.mybatis.dao"></property>

    </bean> -->

</beans>

7、mybatis-config.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>

    <settings>

        <setting name="mapUnderscoreToCamelCase" value="true" />

        <setting name="jdbcTypeForNull" value="NULL" />

        <!--显式的指定每个我们需要更改的配置的值，即使他是默认的。防止版本更新带来的问题 -->

        <setting name="cacheEnabled" value="true" />

        <setting name="lazyLoadingEnabled" value="true" />

        <setting name="aggressiveLazyLoading" value="false" />

    </settings>

    <databaseIdProvider type="DB_VENDOR">

        <property name="MySQL" value="mysql" />

        <property name="Oracle" value="oracle" />

        <property name="SQL Server" value="sqlserver" />

    </databaseIdProvider>

</configuration>

注意：此处mybatis配置文件中没有配置数据源，数据源由spring负责。

此外还需要ehcache.xml配置文件,Mapper.xml文件。
