Spring+Mybatis整合

进入十一月份，依旧没什么事可干，天天在工位上坐着，学点东西也记不住，浪费时间，浪费光阴。Spring框架学到了后面，整合Mybatis，方式有很多。今天花了点时间整合起来，总结一下

按说应该mybatis-spring-1.2.3.jar这个包里的类应该提供完全取代mybatis配置文件的功能，还没有探究过，我还是保留了mybatis配置文件。

第一步：导入所有所需的mybati的jar，导入spring的jar。最重要的导入mybatis-spring-1.2.3.jar

第二步：新建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: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.xsd
http://www.springframework.org/schema/context

<!-- <context:component-scan base-package="com.houjun.utils"></context:component-scan> -->
<context:component-scan base-package="com.houjun.pojo" /><!--用以扫描注解-->
<context:property-placeholder location="jdbc.properties" /><!--导入属性文件-->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<bean class="org.mybatis.spring.SqlSessionFactoryBean"
id="sqlSessionFactory">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation"
value="classpath:sqlMapConfig.xml"></property>
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.houjun.dao"></property>
<property name="sqlSessionFactoryBeanName"
value="sqlSessionFactory"></property>
</bean>

</beans>

第三步：建立mybatis配置文件sqlMapConfig.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="lazyLoadingEnabled" value="true"/><!-- 全局延迟加载开关 -->
    <setting name="aggressiveLazyLoading" value="false"/><!-- 牵一发动全身【专指延迟属性】 -->
    </settings>   
    <typeAliases>
        <package name="com.houjun.pojo" />
    </typeAliases>
</configuration>
