spring 整合druid

一. Spring 配置

<!-- Druid数据源  -->    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">        <property name="driverClassName" value="${db.driver}" />        <property name="url" value="${db.url}" />        <property name="username" value="${db.username}" />        <property name="password" value="${db.password}" />        <!-- 配置初始化大小、最小、最大 -->        <property name="initialSize" value="10" />        <property name="minIdle" value="10" />        <property name="maxActive" value="300" />        <!-- 配置获取连接等待超时的时间 -->        <property name="maxWait" value="1800" />        <!-- 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" />        <!-- mysql SELECT 'x'  Oracle: SELECT 1 FROM DUAL -->        <property name="validationQuery" value="SELECT 'x'" />        <property name="testWhileIdle" value="true" />        <property name="testOnBorrow" value="false" />        <property name="testOnReturn" value="false" />        <!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->        <!-- 如果用Oracle，则把poolPreparedStatements配置为true，mysql可以配置为false。分库分表较多的数据库，建议配置为false。 -->        <property name="poolPreparedStatements" value="true" />        <property name="maxPoolPreparedStatementPerConnectionSize" value="20" />        <!-- 配置监控统计拦截的filters，去掉后监控界面sql无法统计 wall=防火墙 -->        <property name="filters" value="stat" />    </bean>    <!--创建SqlSessionFactory，同时指定数据源-->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource" />        <!--指定mybatis总配置文件，订制的environment在spring容器中不在生效-->        <property name="configLocation">            <value>classpath:mybatis-config.xml</value>        </property>        <property name="mapperLocations">            <list>                <!-- 表示在com.xx以下所有目录中，以.xml结尾所有文件                 mapper/**/*.xml-->                <value>classpath*:mapper/com/xx/**/*.xml</value>            </list>        </property>    </bean>    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">        <constructor-arg index="0" ref="sqlSessionFactory" />    </bean>    <!--事务配置-->    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">         <property name="dataSource" ref="dataSource" />    </bean>    <aop:aspectj-autoproxy />    <tx:advice id="txAdvice" transaction-manager="txManager">        <tx:attributes>            <tx:method name="get*" read-only="true"/>            <tx:method name="load*" read-only="true"/>            <tx:method name="find*" read-only="true"/>            <tx:method name="list*" read-only="true"/>            <tx:method name="query*" read-only="true"/>            <tx:method name="*Query" read-only="true"/>            <tx:method name="*"/>        </tx:attributes>    </tx:advice>    <aop:config>        <aop:advisor pointcut="execution(* com.xx..service.*.*(..))"            advice-ref="txAdvice" order="1" />        <aop:advisor pointcut="execution(* com.xx..manager.*.*(..))"            advice-ref="txAdvice" order="2" />    </aop:config>    <!-- Spring 监控 -->    <bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"/>    <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut">        <property name="patterns">            <list>                <value>com.xx.*</value>            </list>        </property>    </bean>    <aop:config>        <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" />    </aop:config>
