druid 配置監控界面和開啟spring支持

1、配置監控頁面

    <!-- JNDI方式配置數據源 -->
    <!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="${jndiName}"></property> </bean> -->
    <!-- 數據源驅動類可不寫，Druid默認會自動根據URL識別DriverClass -->
    <!-- 配置數據源 -->
    <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
        <property name="url" value="${jdbc_url}"/>
        <property name="driverClassName" value="${driverClassName}"/>
        <property name="username" value="${jdbc_username}"/>
        <property name="password" value="${jdbc_password}"/>

        <!-- 初始化連接大小 -->
        <property name="initialSize" value="${jdbc_initialSize}"/>
        <!-- 連接池最大使用連接數量 -->
        <property name="maxActive" value="${jdbc_maxActive}"/>
        <!-- 連接池最小空閑 -->
        <property name="minIdle" value="${jdbc_minIdle}"/>
        <!-- 獲取連接最大等待時間 -->
        <property name="maxWait" value="${jdbc_maxWait}"/>

        <!-- <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="33" /> -->

        <property name="validationQuery" value="${validationQuery}"/>
        <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"/>

        <!-- 打開removeAbandoned功能 -->
        <property name="removeAbandoned" value="true"/>
        <!-- 1800秒，也就是30分鍾 -->
        <property name="removeAbandonedTimeout" value="1800"/>
        <!-- 關閉abanded連接時輸出錯誤日志 -->
        <property name="logAbandoned" value="true"/>

        <!-- 監控數據庫 -->
        <!-- 配置監控統計攔截的filters -->
        <property name="filters" value="stat,wall,log4j"/>
        <!-- 監控統計攔截的filters -->
        <!-- 並在filters屬性中配置了log4j -->
        <property name="proxyFilters">
            <list>
                <ref bean="stat-filter"/>
                <ref bean="log-filter"/>
            </list>
        </property>
        <!--<property name="filters" value="mergeStat"/>-->
    </bean>
    <!-- 慢SQL記錄-->
    <bean id="stat-filter" class="com.alibaba.druid.filter.stat.StatFilter">
        <property name="mergeSql" value="true"/>
        <property name="slowSqlMillis" value="10000"/>
        <property name="logSlowSql" value="true"/>
    </bean>
    <bean id="log-filter" class="com.alibaba.druid.filter.logging.Log4jFilter">
        <!-- <property name="resultSetLogEnabled" value="false" /> -->
        <!-- <property name="statementExecutableSqlLogEnable" value="true" /> -->
    </bean>

web.XML增加如下servlet 

    <!-- 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>128.242.127.1/24,127.0.0.1</param-value>
        </init-param>
        <init-param>
            <param-name>deny</param-name>
            <param-value>192.168.1.118</param-value>
        </init-param>
        <init-param>
            <param-name>resetEnable</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <!-- 用戶名 -->
            <param-name>loginUsername</param-name>
            <param-value>admin</param-value>
        </init-param>
        <init-param>
            <!-- 密碼 -->
            <param-name>loginPassword</param-name>
            <param-value>admin</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>DruidStatView</servlet-name>
        <url-pattern>/druid/*</url-pattern>
    </servlet-mapping>

2、配置spring支持

   在WEB.XML文件中增加 如下filter
<!-- druid url monitor setting start -->
    <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>
    <!-- druid url monitor setting end -->

在spring.xml頁面增加如下節點。 
   <!-- 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>giftcard.modules.erp.service.*</value>
                <value>giftcard.modules.erp.dao.*</value>
            </list>
        </property>
    </bean>
    <aop:config proxy-target-class="true">
        <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut"/>
    </aop:config>
