配置数据源

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
        <!--MySQL驱动-->
        <property name="driverClassName" value="${db.driverClassName}"/>
        <!--MySQL连接的url-->
        <property name="url" value="${db.url}"/>
        <!--连接数据库的名称-->
        <property name="username" value="${db.username}"/>
        <!--连接数据库的密码-->
        <property name="password" value="${db.password}"/>
        <!--初始化的大小-->
        <property name="initialSize" value="3"/>
        <!--数据库连接池——最小空余的数量-->
        <property name="minIdle" value="3"/>
        <!--数据库连接池——最大的活跃数量-->
        <property name="maxActive" value="20"/>
        <!--最长等待时间,一旦超过该时间则认为是超时-->
        <property name="maxWait" value="60000"/>
        <!--过滤器-->
        <property name="filters" value="stat,wall"/>
        <!--proxyFilters是代理filter的意思-->
        <property name="proxyFilters">
            <list>
                <ref bean="log4j2-filter"/>
            </list>
        </property>
    </bean>

  在这里,由于日志的记录并不是由Druid执行的,而是由log4j2因而我们需要在这里指明proxyFilters为log4j2-filter
配置log4j2-filter

<!--配置log4j2的Log4j2Filter-->
    <bean id="log4j2-filter" class="com.alibaba.druid.filter.logging.Log4j2Filter">
        <property name="connectionLogEnabled" value="false"/>
        <property name="statementLogEnabled" value="false"/>
        <property name="resultSetLogEnabled" value="true"/>
        <property name="statementExecutableSqlLogEnable" value="true"/>
    </bean>

  在这里,我们开发项目时有时非常想看在控制台中打印的SQL信息,所以说我们会将resultSetLogEnabled设置为true,如果不想查看,那么我们只需要将其更改为false即可。
配置log4j2.xml

  在Druid官网中说,下面的配置是可以在项目中直接拿来使用的,所以说我就不做什么修改,直接将其贴出来,如果想看源文档的话,可以访问Druid中使用log4j2进行日志输出
