web.xml文件：Web.xml文件是整个web应用中最重要的配置文件，它必须放在WEB-INF目录中。在开发web应用时，但凡涉及到对web应用中的web资源进行配置，通通是在web.xml文件中进行设置。
注意：通过web.xml文件把某个web资源配成网站首页。

1.开启服务器Tomcat访问HTML文件
2.若想改变地址或端口号来访问html文件的方法是
（1）首先改在tomcat目录下的conf下的文件server.html
<Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" /><!--改端口号-->
<Host name="yan_mei" appBase="webapps"
unpackWARs="true" autoDeploy="true"></Host><!--改地址-->
（2）改地址前可能会出现问题，找不到文件，解决办法
在c盘下的C:\Windows\System32\Drivers\etc的文件下修改hosts
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
127.0.0.1 yan_mei
