1.新增資料庫連結依賴

<!-- 新增資料庫連線池依賴 -->
<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>druid</artifactId>
	<version>1.0.29</version>
</dependency>

2.spring-mybatis.xml配置

<!-- 配置資料來源 使用的是Druid資料來源 -->  
    <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource"  
        init-method="init" destroy-method="close">  
        <property name="url" value="${jdbc.url}" />  
        <property name="username" value="${jdbc.username}" />  
        <property name="password" value="${jdbc.password}" />  
  
        <!-- 初始化連線大小 -->  
        <property name="initialSize" value="0" />  
        <!-- 連線池最大使用連線數量 -->  
        <property name="maxActive" value="20" />  
          
        <!-- 連線池最小空閒 -->  
        <property name="minIdle" value="0" />  
        <!-- 獲取連線最大等待時間 -->  
        <property name="maxWait" value="60000" />  
        <property name="poolPreparedStatements" value="true" />  
        <property name="maxPoolPreparedStatementPerConnectionSize"  
            value="33" />
        <!-- 用來檢測有效sql -->  
        <property name="validationQuery" value="SELECT 1 FROM DUAL" />  
        <property name="testOnBorrow" value="false" />  
        <property name="testOnReturn" value="false" />  
        <property name="testWhileIdle" value="true" />  
        <!-- 配置間隔多久才進行一次檢測，檢測需要關閉的空閒連線，單位是毫秒 -->  
        <property name="timeBetweenEvictionRunsMillis" value="60000" />  
        <!-- 配置一個連線在池中最小生存的時間，單位是毫秒 -->  
        <property name="minEvictableIdleTimeMillis" value="25200000" />  
        <!-- 開啟removeAbandoned功能 -->  
        <property name="removeAbandoned" value="true" />  
        <!-- 1800秒，也就是30分鐘 -->  
        <property name="removeAbandonedTimeout" value="1800" />  
        <!-- 關閉abanded連線時輸出錯誤日誌 -->  
        <property name="logAbandoned" value="true" />  
        <!-- 監控資料庫 -->  
        <property name="filters" value="stat,wall,log4j" />  
        </bean>
 

3.web.xml配置新增如下程式碼  設定使用者名稱user 密碼123456

<!-- druid監控 -->
    <servlet>
        <servlet-name>DruidStatView</servlet-name>
        <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
        <!--
            deny優先於allow，如果在deny列表中，就算在allow列表中，也會被拒絕。
            如果allow沒有配置或者為空，則允許所有訪問
         -->
        <init-param>
            <param-name>allow</param-name>
            <param-value>192.168.3.120,127.0.0.1</param-value>
        </init-param>
        <init-param>
            <param-name>deny</param-name>
            <param-value>192.168.3.120</param-value>
        </init-param>
        <init-param>
            <param-name>resetEnable</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <!-- 使用者名稱 -->
            <param-name>loginUsername</param-name>
            <param-value>user</param-value>
        </init-param>
        <init-param>
            <!-- 密碼 -->
            <param-name>loginPassword</param-name>
            <param-value>123456</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>DruidStatView</servlet-name>
        <url-pattern>/druid/*</url-pattern>
    </servlet-mapping>
 

 5.下面是配置spring監控

spring.xml新增

 <!-- druid spring monitor setting -->
    <bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"/>
    <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut" scope="prototype">
        <property name="patterns">
            <list>
                <value>com.test.service.*</value>
            </list>
        </property>
    </bean>
    <aop:config proxy-target-class="true">
        <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut"/>
    </aop:config>
 

web.xml新增

<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>
        <init-param>
            <param-name>profileEnable</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>DruidWebStatFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

成功
