druid（德鲁伊）数据源的使用和配置

pom.xml

<dependency>     <groupId>com.alibaba</groupId>     <artifactId>druid</artifactId>     <version>1.0.9</version> </dependency>

现看配置吧：

jdbc.properties

druid.url=jdbc:mysql://localhost:3306/ulewo?useUnicode=true&characterEncoding=utf8&autoReconnect=true druid.driverClassName=com.mysql.jdbc.Driver   druid.username=root druid.password=root         druid.filters=stat     druid.maxActive=20 druid.initialSize=1 druid.maxWait=60000 druid.minIdle=10 maxIdle:100       druid.timeBetweenEvictionRunsMillis=60000 druid.minEvictableIdleTimeMillis=300000     druid.validationQuery=SELECT ‘x‘ druid.testWhileIdle=true druid.testOnBorrow=false druid.testOnReturn=false #poolPreparedStatements:true   druid.maxOpenPreparedStatements=20    #对于建立连接过长的连接强制关闭   druid.removeAbandoned:true #如果连接建立时间超过了30分钟，则强制将其关闭   druid.removeAbandonedTimeout:1800 #将当前关闭动作记录到日志   druid.logAbandoned:true

spring配置：

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"           destroy-method="close">           <property name="url" value="${druid.url}" />           <property name="username" value="${druid.username}" />           <property name="password" value="${druid.password}" />           <property name="driverClassName" value="${druid.driverClassName}" />           <property name="filters" value="${druid.filters}" />              <property name="maxActive" value="${druid.maxActive}" />           <property name="initialSize" value="${druid.initialSize}" />           <property name="maxWait" value="${druid.maxWait}" />           <property name="minIdle" value="${druid.minIdle}" />              <property name="timeBetweenEvictionRunsMillis" value="${druid.timeBetweenEvictionRunsMillis}" />           <property name="minEvictableIdleTimeMillis" value="${druid.minEvictableIdleTimeMillis}" />              <property name="validationQuery" value="${druid.validationQuery}" />           <property name="testWhileIdle" value="${druid.testWhileIdle}" />           <property name="testOnBorrow" value="${druid.testOnBorrow}" />           <property name="testOnReturn" value="${druid.testOnReturn}" />           <property name="maxOpenPreparedStatements"               value="${druid.maxOpenPreparedStatements}" />           <property name="removeAbandoned" value="${druid.removeAbandoned}" /> <!-- 打开removeAbandoned功能 -->           <property name="removeAbandonedTimeout" value="${druid.removeAbandonedTimeout}" /> <!-- 1800秒，也就是30分钟 -->           <property name="logAbandoned" value="${druid.logAbandoned}" /> <!-- 关闭abanded连接时输出错误日志 -->       </bean>
