druid 配置监控页面和开启防火墙，spring

1. dataSource中增加

<property name="filters" value="stat,wall"/>

2. spring 中增加（spring的支持）

<!-- druid spring monitor setting -->
<!-- 开启@AspectJ AOP代理 -->
    
    <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.beta.mss.core.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>

需要注意的是这里的patterns中一般只监控service，controller监控不到，同时spring代理使用CGLib的代理方式，但是CGLib不能代理final类或被private，final修饰的方法，CGLib面对具体代理类，不能是接口，jdk的代理是面向接口的。

3. web.xml

<!-- 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>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>DruidWebStatFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- druid url monitor setting end -->
