Druid链接池-配置监控界面

1.Spring-dataSource.xml 中的数据链接池配置加入拦截

<!-- 配置监控统计拦截的filters，去掉后监控界面sql没法统计 -->

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

2.web.xml 中配置druid监控用于展现

<!--  配置druid监控-->
  <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>
  </filter>
  <filter-mapping>
    <filter-name>DruidWebStatFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <servlet>
    <servlet-name>DruidStatView</servlet-name>
    <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>DruidStatView</servlet-name>
    <url-pattern>/druid/*</url-pattern>
  </servlet-mapping>
