<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">

<property
name="password" value="${jdbc.mysql.master.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"

<!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->
<property

<property

/>
<!-- 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" />
</bean>
Web.xml配置文件中添加
<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>
<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>
