1. Add Durid connection pool dependency in Maven
<!-- druid连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.29</version> </dependency>
2 , Configure Druid data source in Spring, and set monitoring parameters
<!-- druid数据源 -->
<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="${db.url}" />
<property name="username" value="${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" value="false" />
<!-- 配置监控统计拦截的filters -->
<property name="filters" value="stat" />
</bean>
3. Configure Druid monitoring Servlet## in web.xml
#<!-- druid监控 --> <servlet> <servlet-name>DruidStatView</servlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class> <init-param> <!-- 用户名 --> <param-name>loginUsername</param-name> <param-value>druid</param-value> </init-param> <init-param> <!-- 密码 --> <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>
