<!--第一步:加载配置数据库相关参数-->
<context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>
<!--第二步:数据库连接池-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<!--配置连接池属性-->
<property name="driverClassName" value="${jdbc.driverClass}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
<!-- 配置初始化大小、最小、最大 -->
<property name="initialSize" value="1" />
<property name="minIdle" value="1" />
<property name="maxActive" value="20" />
<!-- 配置获取连接等待超时的时间 -->
<property name="maxWait" value="60000" />
<!-- 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间,单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000" />
</bean>
<!-- 第三步:sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:mybatis-config.xml"/>
<property name="mapperLocations" value="classpath*:com/eaglesoul/assistant/dao/mapper/*.mapper"/>
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 第四步:配置mapper接口,创建动态代理类,并注册到ioc容器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.eaglesoul.assistant.dao"/>
</bean>
