<!-- 添加Web应用等监控-->
<filter>
    <filter-name>DruidWebStatFilter</filter-name>
    <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
    <init-param>
        <param-name>exclusions</param-name>

2、拦截器 SessionFilter

// 以下的文件不进行过滤
        if (uri.startsWith(projectName + "/druid")//支持连接池页面
            )
        {
            arg2.doFilter(arg0, arg1);
        }

3、数据源配置

<?xml version="1.0" encoding="UTF-8"?>
<Context path="/erpfoko" >
    <Resource auth="Container"
              driverClassName="oracle.jdbc.driver.OracleDriver"
              maxActive="50"
              maxIdle="20"
              maxWait="10000"
              name="jdbc/btdb1"
              type="javax.sql.DataSource"
              factory="com.alibaba.druid.pool.DruidDataSourceFactory"
              url="jdbc:oracle:thin:@localhost:1521/orcl"
              username="swyy_0915"
              password="swyy_0915"
              filters="stat"
    />
    <Resource auth="Container"
              driverClassName="oracle.jdbc.driver.OracleDriver"
              maxActive="50"
              maxIdle="20"
              maxWait="10000"
              name="jdbc/btdb2"
              type="javax.sql.DataSource"
              factory="com.alibaba.druid.pool.DruidDataSourceFactory"
              url="jdbc:oracle:thin:@localhost:1521/orcl"
              username="swyy_0915"
              password="swyy_0915"
              filters="stat"
    />
</Context>
