阿里druid连接池监控数据自定义存储

如何将druid连接池监控到的sql执行效率，连接池资源情况等进行持久化存储，方便系统运维分析优化，以下案例初步测试成功。

第一部：

新建MyDruidStatLogger类实现接口 extends DruidDataSourceStatLoggerAdapter implements DruidDataSourceStatLogger,详细代码如下：本实例只实现接收消息并在控制台打印，实际业务应用需要具体实现存储方案。

            String text = JSONUtils.toJSONString(map);
            System.out.println("==============:"+text);
    }
}

第二步：配置spring bean

<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">   
   <!-- 基本属性 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" />  
   <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 -->  
   <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 -->  
   <property name="filters" value="stat" />   
   <property name="timeBetweenLogStatsMillis" value="1000" />
   <property name="statLogger" ref="myStatLogger"/>
</bean>

启动后就可以看到控制台打印的durid监控信息了。
