Tomcat配置虚拟路径映射失败分析

Tomcat配置虚拟路径映射失败，一定要看这里！
配置Tomcat路径映射
在tomcat安装目录下的conf/server.xml里，在< Host >标签内添加

	    <Context path="/{访问路径}"  docBase="{实际路径}" reloadable="true" crossContext="true">
		Context>

例：

	    <Context path="/local"  docBase="F://dir" reloadable="true" crossContext="true">
		Context>

经试验，路径里的斜杆是正反斜杆都可
盘符后的斜杆可以是单双斜杆
对于F://dir/aa.txt,使用http://localhost:8080/local/dir/aa.txt进行访问
若失败，请检查：

1.在idea运行配置里勾选使用tomcat的配置

2.不能从盘符映射

这样是不会成功的（访问不到）：

	    <Context path="/local"  docBase="F://" reloadable="true" crossContext="true">
		Context>

这样也不会成功（启动失败）：

	    <Context path="/local"  docBase="F:" reloadable="true" crossContext="true">
		Context>

实际路径不能是盘符，只能从目录映射，如F:/dir

附：tomcat启动过程中出现的错误，不影响映射的成功：
