如何將druid鏈接池監控到的sql執行效率，鏈接池資源狀況等進行持久化存儲，方便系統運維分析優化，如下案例初步測試成功。java

第一部：web

新建MyDruidStatLogger類實現接口 extends DruidDataSourceStatLoggerAdapter implements DruidDataSourceStatLogger,詳細代碼以下：本實例只實現接收消息並在控制檯打印，實際業務應用須要具體實現存儲方案。spring

            System.out.println("==============:"+text);
    }
}

第二步：配置spring beansql

<bean id="myStatLogger" class="com.andaily.web.context.MyDruidStatLogger"> </bean>

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">   
   <!-- 基本屬性 url、user、password -->  
   <property name="url" value="${jdbc.url}" />  
   <property name="username" value="${jdbc.username}" />  
   <property name="password" value="${jdbc.password}" />  
       
   <!-- 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" />  
  
   <!-- 配置獲取鏈接等待超時的時間 -->  
   <property name="maxWait" value="60000" />  
  
   <!-- 配置間隔多久才進行一次檢測，檢測須要關閉的空閒鏈接，單位是毫秒 -->  
   <property name="timeBetweenEvictionRunsMillis" value="60000" />  
   <!-- 配置一個鏈接在池中最小生存的時間，單位是毫秒 -->  
   <property name="minEvictableIdleTimeMillis" value="300000" />  
   <property name="validationQuery" value="SELECT 'x'" />  
   <property name="testWhileIdle" value="true" />  
   <property name="testOnBorrow" value="false" />  
   <property name="testOnReturn" value="false" />  
   <!-- 打開PSCache，而且指定每一個鏈接上PSCache的大小 -->  
   <property name="poolPreparedStatements" value="true" />  
   <property name="maxPoolPreparedStatementPerConnectionSize" value="20" />  
  
   <!-- 配置監控統計攔截的filters，去掉後監控界面sql沒法統計 -->  
   <property name="filters" value="stat" />   
   <property name="timeBetweenLogStatsMillis" value="1000" />
   <property name="statLogger" ref="myStatLogger"/>
</bean>

啓動後就能夠看到控制檯打印的durid監控信息了。json
