Ali druid custom connection pool monitoring data storage

How druid connection pool to monitor the efficiency of sql, connection pooling resources such as persistent storage, easy operation and maintenance system analysis and optimization, preliminary test the following success stories.

First:

MyDruidStatLogger new class implements the interface extends DruidDataSourceStatLoggerAdapter implements DruidDataSourceStatLogger, detailed code as follows: examples of the realization only receives the message printed on the console, the actual business application needs embodied storage scheme.

Step Two: Configure 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}"  /> <-! configuration initial size, minimum, maximum -> < Property name = "initialSize" value = ". 1" /> < Property name = " minIdle " value =". 1 " /> < Property name =" for maxActive " value =" 20 is " /> <-! configuration acquiring connection waiting timeout -> < Property name =" maxWait " value =" 60000 " / > <!- intervals the frequency of such detection, an idle connection is detected to be closed, in milliseconds -> <

After the start you can see durid monitoring console to print the information.
