Druid提供了Spring和Jdbc的关联监控。

com.alibaba.druid.support.spring.stat.DruidStatInterceptor是一个标准的Spring MethodInterceptor。可以灵活进行AOP配置。

Spring AOP的配置文档： http://static.springsource.org/spring/docs/current/spring-framework-reference/html/aop-api.html

按类型拦截配置

  <bean id="druid-stat-interceptor"
      class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor">
  </bean>

  <bean id="druid-type-proxyCreator" class="com.alibaba.druid.support.spring.stat.BeanTypeAutoProxyCreator">
      <!-- 所有ABCInterface的派生类被拦截监控  -->
      <property name="targetBeanType" value="xxxx.ABCInterface" />
      <property name="interceptorNames">
          <list>
              <value>druid-stat-interceptor</value>
          </list>
      </property>
  </bean>

方法名正则匹配拦截配置

  <bean id="druid-stat-interceptor"
      class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor">
  </bean>

<bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut"
    scope="prototype">
    <property name="patterns">
        <list>
            <value>com.mycompany.service.*</value>
            <value>com.mycompany.dao.*</value>
        </list>
    </property>
</bean>

<aop:config>
    <aop:advisor advice-ref="druid-stat-interceptor"
        pointcut-ref="druid-stat-pointcut" />
</aop:config>

有些情况下，可能你需要配置proxy-target-class，例如：

<aop:config proxy-target-class="true">
    <aop:advisor advice-ref="druid-stat-interceptor"
        pointcut-ref="druid-stat-pointcut" />
</aop:config>

##按照BeanId来拦截配置

  <bean id="druid-stat-interceptor"
      class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor">
  </bean>

<bean
    class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
    <property name="proxyTargetClass" value="true" />
    <property name="beanNames">
        <list>
            <!-- 这里配置需要拦截的bean id列表 -->
            <value>xxx-dao</value>
            <value>xxx-service</value>
        </list>
    </property>
    <property name="interceptorNames">
        <list>
            <value>druid-stat-interceptor</value>
        </list>
    </property>
</bean>
