阿里云ECS中Tomcat启动报错：指定的主资源集 [C:\upload] 无效

Question

我需要Tomcat映射本地资源路径，不过配置完成后启动报错：指定的主资源集无效

环境配置：

1.jdk:1.8
2.tomcat:9.0
3.服务器：windows servers 2008 r2

这是我server.xml中映射配置：

<Context docBase="C:\upload" path="/upload" debug="0" reloadable="true" />

我试过的方法：

1.修改C:\upload文件的用户权限，没结果。
2.使用管理员身份运行startup.bat，没结果。
3.修改tomcat中的web.xml中的listens为true,没结果。
4.去掉server.xml中的映射语句，启动成功，不过上传文件报错，我要的是映射出去，所以这个方法还是没结果。
