一、Maven中添加Durid連接池依賴

<!-- druid連接池 -->
<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid</artifactId>
  <version>1.0.29</version>
</dependency>

二、Spring 中配置Druid數據源，並設置監控參數

<!-- druid數據源 -->
<bean id="dataSource" class
 
="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
  <!-- 基本屬性 url、user、password -->
  <property name="url" value="${db.url}" />
  <property name="username" value="${db.username}" />
  <property name="password" value="${db.password}" />

  <!-- 配置初始化大小、最小、最大 -->
  <property name="initialSize" value="20" />
  <property name="minIdle" value="1" />
  <property name="maxActive" value="40" />

  <!-- 配置獲取連接等待超時的時間 -->
  <property name="maxWait" value="60000" />

  <!-- 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒 -->
  <property name="timeBetweenEvictionRunsMillis" value="60000" />

  <!-- 配置一個連接在池中最小生存的時間，單位是毫秒 -->
  <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" />

  <!-- 配置監控統計攔截的filters -->
  <property name="filters" value="stat" />
  </bean>

三、web.xml中配置Druid監控的Servlet

<!-- druid監控 -->
  <servlet>
  <servlet-name>DruidStatView</servlet-name>
  <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
  <init-param>
  <!-- 用戶名 -->
  <param-name>loginUsername</param-name>
  <param-value>druid</param-value>
  </init-param>
  <init-param>
  <!-- 密碼 -->
  <param-name>loginPassword</param-name>
  <param-value>bounter</param-value>
  </init-param>
  </servlet>
  <servlet-mapping>
  <servlet-name>DruidStatView</servlet-name>
  <url-pattern>/druid/*
 
</url-pattern>
  </servlet-mapping>

四、瀏覽器訪問 http://localhost:8080/druid/
