druid 配置监控界面和开启spring支持

1、配置监控页面

    <!-- JNDI方式配置数据源 -->
    <!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="${jndiName}"></property> </bean> -->
    <!-- 数据源驱动类可不写，Druid默认会自动根据URL识别DriverClass -->
    <!-- 配置数据源 -->
    <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
        <property name="url" value="${jdbc_url}"/>
        <property name="driverClassName" value="${driverClassName}"/>
        <property name="username" value="${jdbc_username}"/>
        <property name="password" value="${jdbc_password}"/>

        <!-- 初始化连接大小 -->
        <property name="initialSize" value="${jdbc_initialSize}"/>
        <!-- 连接池最大使用连接数量 -->
        <property name="maxActive" value="${jdbc_maxActive}"/>
        <!-- 连接池最小空闲 -->
        <property name="minIdle" value="${jdbc_minIdle}"/>
        <!-- 获取连接最大等待时间 -->
        <property name="maxWait" value="${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"/>

        <!-- 打开removeAbandoned功能 -->
        <property name="removeAbandoned" value="true"/>
        <!-- 1800秒，也就是30分钟 -->
        <property name="removeAbandonedTimeout" value="1800"/>
        <!-- 关闭abanded连接时输出错误日志 -->
        <property name="logAbandoned" value="true"/>

        <!-- 监控数据库 -->
        <!-- 配置监控统计拦截的filters -->
        <property name="filters" value="stat,wall,log4j"/>
        <!-- 监控统计拦截的filters -->
        <!-- 并在filters属性中配置了log4j -->
        <property name="proxyFilters">
            <list>
                <ref bean="stat-filter"/>
                <ref bean="log-filter"/>
            </list>
        </property>
        <!--<property name="filters" value="mergeStat"/>-->
    </bean>
    <!-- 慢SQL记录-->
    <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监控 -->
    <servlet>
        <servlet-name>DruidStatView</servlet-name>
        <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
        <!--
            deny优先于allow，如果在deny列表中，就算在allow列表中，也会被拒绝。
            如果allow没有配置或者为空，则允许所有访问
         -->
        <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>
            <!-- 用户名 -->
            <param-name>loginUsername</param-name>
            <param-value>admin</param-value>
        </init-param>
        <init-param>
            <!-- 密码 -->
            <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>

登录地址：http://localhost:8099/erp/druid

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页面增加如下节点。 
   <!-- 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>
