Druid configuration and built-in monitoring, Web page view monitoring content

1. Configuring the Druid built-in monitoring

First introduce the package in the Pom.xml of the MAVEN project

<dependency>    <groupId>com.alibaba</groupId>    <artifactid>druid</artifactid >    <version>${druid-version}</version></dependency>

2. Configure the spring configuration file after the package is introduced

<!--reading configuration Files -<BeanID= "Propertyconfigurer"class= "Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">    < Propertyname= "Locations">         <List>             <value>Classpath:jdbc.properties</value>         </List>     </ Property></Bean><!--Druid JNDI DataSource for EE environments -<BeanID= "DataSource"class= "Com.alibaba.druid.pool.DruidDataSource"Init-method= "Init"Destroy-method= "Close">    < Propertyname= "url"value= "${jdbc.url}" />    < Propertyname= "username"value= "${jdbc.username}" />    < Propertyname= "Password"value= "${jdbc.password}" />    < Propertyname= "Maxactive"value= " the" />    < Propertyname= "InitialSize"value= "1" />    < Propertyname= "Maxwait"value= "60000" />    < Propertyname= "Minidle"value= "1" />    < Propertyname= "Timebetweenevictionrunsmillis"value= " the" />    < Propertyname= "Minevictableidletimemillis"value= "300000" />    < Propertyname= "Validationquery"value= "Select ' x ' from DUAL" />    < Propertyname= "Testwhileidle"value= "true" />    < Propertyname= "Testonborrow"value= "false" />    < Propertyname= "Testonreturn"value= "false" />       <!--MySQL does not support poolpreparedstatements -    <!--<property name= "poolpreparedstatements" value= "true"/> -    <!--<property name= "maxpoolpreparedstatementperconnectionsize" value= "/> " -       <!--turn on the Druid Monitoring statistics function -    < Propertyname= "Filters"value= "Stat" /></Bean>

Then open the monitoring service in Web. xml

<!--Adding Druid monitoring -   <servlet>      <Servlet-name>Druidstatview</Servlet-name>      <Servlet-class>Com.alibaba.druid.support.http.StatViewServlet</Servlet-class>  </servlet>  <servlet-mapping>      <Servlet-name>Druidstatview</Servlet-name>      <Url-pattern>/druid/*</Url-pattern>  </servlet-mapping><!--add monitoring such as Web apps -  <Filter>    <Filter-name>Druidwebstatfilter</Filter-name>    <Filter-class>Com.alibaba.druid.support.http.WebStatFilter</Filter-class>    <Init-param>        <Param-name>Exclusions</Param-name>        <Param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*</Param-value>    </Init-param>    <Init-param>        <Param-name>Profileenable</Param-name>        <Param-value>True</Param-value>    </Init-param>    <Init-param>        <Param-name>Principalcookiename</Param-name>        <Param-value>User_cookie</Param-value>    </Init-param>    <Init-param>        <Param-name>Principalsessionname</Param-name>        <Param-value>User_session</Param-value>    </Init-param></Filter><filter-mapping>    <Filter-name>Druidwebstatfilter</Filter-name>    <Url-pattern>/*</Url-pattern></filter-mapping>

Well, after the top three steps, you can monitor it. Visit Page Http://127.0.0.1:8080/{projectname}/druid/ Index.html can access the Monitoring page, Druid has data-friendly display to the page, including the number of times per SQL execution, execution time, the slowest time, and so much more detailed information, for our reference, to find out which are inefficient and time-consuming statements to optimize. At the same time provide data sources, SQL firewall, Web applications, URI monitoring, session monitoring, spring monitoring, etc., there are detailed information about various data, we can refer to the reference. ProjectName is the project name
