WebDAV是一種超文本傳輸協議，Tomcat默認是支持WebDAV的，且默認為禁用狀態。

更多詳細信息，請參考：

https://zh.wikipedia.org/wiki/WebDAV

http://www.webdav.org/

開啟步驟如下：

1、在Tomcat的webapps目錄下新建webdav文件夾，并在此文件夾下新建WEB-INF\web.xml文件

完整的文件目錄為：C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\webdav\WEB-INF\web.xml

配置Servlet，添加如下節點：

<servlet><servlet-name>webdav</servlet-name><servlet-class>org.apache.catalina.servlets.WebdavServlet</servlet-class><init-param><param-name>debug</param-name><param-value>0</param-value></init-param><init-param><param-name>listings</param-name><param-value>true</param-value></init-param><!-- Read-Write Access Settings --><init-param><param-name>readonly</param-name><param-value>false</param-value></init-param></servlet><!-- URL Mapping --><servlet-mapping><servlet-name>webdav</servlet-name><url-pattern>/*</url-pattern></servlet-mapping>

配置權限，添加如下節點：

　　<security-constraint><web-resource-collection><web-resource-name>webdav</web-resource-name><!-- Detect WebDAV Methods in URL For Whole Application --><url-pattern>/*</url-pattern><http-method>PROPFIND</http-method><http-method>PROPPATCH</http-method><http-method>COPY</http-method><http-method>MOVE</http-method><http-method>LOCK</http-method><http-method>UNLOCK</http-method></web-resource-collection><!-- Restrict access by role --><auth-constraint><role-name>*</role-name></auth-constraint></security-constraint><login-config><auth-method>BASIC</auth-method><realm-name>webdav</realm-name></login-config><security-role><description>WebDAV User</description><role-name>webdav</role-name></security-role>

提示：<role-name>為自定義權限名稱。

根據上面權限名稱，在Tomcat賬號體系中增加賬號密碼，配置如下：

打開C:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\tomcat-users.xml

<role rolename="webdav"/><user username="root" password="root" roles="webdav"/>

提示：權限名稱必須和web.xml文件配置的一一對應。

完整的web.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><display-name>webdav</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><servlet><servlet-name>webdav</servlet-name><servlet-class>org.apache.catalina.servlets.WebdavServlet</servlet-class><init-param><param-name>debug</param-name><param-value>0</param-value></init-param><init-param><param-name>listings</param-name><param-value>true</param-value></init-param><!-- Read-Write Access Settings --><init-param><param-name>readonly</param-name><param-value>false</param-value></init-param></servlet><!-- URL Mapping --><servlet-mapping><servlet-name>webdav</servlet-name><url-pattern>/*</url-pattern></servlet-mapping><security-constraint><web-resource-collection><web-resource-name>webdav</web-resource-name><!-- Detect WebDAV Methods in URL For Whole Application --><url-pattern>/*</url-pattern><http-method>PROPFIND</http-method><http-method>PROPPATCH</http-method><http-method>COPY</http-method><http-method>MOVE</http-method><http-method>LOCK</http-method><http-method>UNLOCK</http-method></web-resource-collection><!-- Restrict access by role --><auth-constraint><role-name>*</role-name></auth-constraint></security-constraint><login-config><auth-method>BASIC</auth-method><realm-name>webdav</realm-name></login-config><security-role><description>WebDAV User</description><role-name>webdav</role-name></security-role> </web-app>

配置完成后，重啟Tomcat，然后訪問站點，出現如下樣式證明已經成功：
