2.spring.xml配置druid

<!-- 配置druid数据源 -->
	<bean name="dataSource"
		class="com.alibaba.druid.pool.DruidDataSource" init-method="init"
		destroy-method="close">
		<!-- 数据库连接基础信息 -->
		<property name="url" value="jdbc:mysql://localhost:3306/[databases]?useUnicode=ture&amp;characterEncoding=UTF-8&amp;serverTimezone=UTC"/>
		<property name="username" value="root" />
		<property name="password" value="123456" />
		<property name="driverClassName" value="com.mysql.cj.jdbc.Driver"></property>
		<!-- 初始化连接大小 -->
		<property name="initialSize" value="10" />
		<!-- 连接池最大使用连接数量 -->
		<property name="maxActive" value="20" />
		<!-- 连接池最小空闲 -->
		<property name="minIdle" value="10" />
		<!-- 获取连接最大等待时间 -->
		<property name="maxWait" value="60000" />

		<!-- 监控数据库 -->
		<property name="filters" value="stat" />
	</bean>

	<bean id="jdbcTemplate"
		class="org.springframework.jdbc.core.JdbcTemplate">
		<property name="dataSource" ref="dataSource" />
	</bean>

3.web.xml配置

<!-- 添加druid监控-->   
<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>
<!-- 添加Web应用等监控-->  
<filter>
    <filter-name>DruidWebStatFilter</filter-name>
    <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
    <init-param>

        <param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>DruidWebStatFilter</filter-name>
