druid-StatViewServlet配置

1. 配置web.xml

StatViewServlet是一個標準的javax.servlet.http.HttpServlet，須要配置在你web應用中的WEB-INF/web.xml中。

<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>

根據配置中的url-pattern來訪問內置監控頁面，若是是上面的配置，內置監控頁面的首頁是/druid/index.html
例如：
http://110.76.43.235:9000/druid/index.html
http://110.76.43.235:8080/mini-web/druid/index.html

1.1 配置監控頁面訪問密碼

須要配置Servlet的 loginUsername 和 loginPassword這兩個初始參數。
<!-- 配置 Druid 監控信息顯示頁面 -->

<servlet>
    <servlet-name>DruidStatView</servlet-name>
    <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
    <init-param>
        <!-- 容許清空統計數據 -->
        <param-name>resetEnable</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
        <!-- 用戶名 -->
        <param-name>loginUsername</param-name>
        <param-value>druid</param-value>
    </init-param>
    <init-param>
        <!-- 密碼 -->
        <param-name>loginPassword</param-name>
        <param-value>druid</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>DruidStatView</servlet-name>
    <url-pattern>/druid/*</url-pattern>
</servlet-mapping>

2. 配置allow和deny

StatViewSerlvet展現出來的監控信息比較敏感，是系統運行的內部狀況，若是你須要作訪問控制，能夠配置allow和deny這兩個參數。好比：

<servlet>
    <servlet-name>DruidStatView</servlet-name>
    <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
    <init-param>
        <param-name>allow</param-name>
        <param-value>128.242.127.1/24,128.242.128.1</param-value>
    </init-param>
    <init-param>
        <param-name>deny</param-name>
        <param-value>128.242.127.4</param-value>
    </init-param>
</servlet>
