Druid连接池及监控在spring配置如下：  
\[html\] view plaincopy  
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">     
        
    <property name="url" value="$\{jdbc\_url\}" />    
    <property name="username" value="$\{jdbc\_user\}" />    
    <property name="password" value="$\{jdbc\_password\}" />    
          
        
    <property name="initialSize" value="1" />    
    <property name="minIdle" value="1" />     
    <property name="maxActive" value="20" />    
     
        
    <property name="maxWait" value="60000" />    
     
        
    <property name="timeBetweenEvictionRunsMillis" value="60000" />    
     
        
    <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" />    
     
        
    <property name="poolPreparedStatements" value="true" />    
    <property name="maxPoolPreparedStatementPerConnectionSize" value="20" />    
     
        
    <property name="filters" value="stat" />     
</bean>    
 只要配置initialSize，maxActive就可以,目前这样的配置已经能够使用连接池，加入其实配置性能不好,官方文档里也不没加其它属性，连接池jar包免费下载。  
然后是监控的配置：  
web.xml  
\[html\] view plaincopy  
<span style="white-space:pre">  </span><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>    
      </filter>    
      <filter-mapping>    
        <filter-name>DruidWebStatFilter</filter-name>    
        <url-pattern>/\*</url-pattern>    
      </filter-mapping>    
filter可以监控webURl 访问  
\[html\] view plaincopy  
<span style="white-space:pre">  </span><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>    
该配置可以访问监控界面，配置好后，访问http://ip地址:端口号/项目名/druid/index.html即可监控数据库访问性能。
