一、需求
去掉项目工程名称访问，比如 http://ganhuopu.run:2001/blog ，要去掉blog这个工程名，变成 http://ganhuopu.run:2001可以访问。
二、解决方案
这时候就要修改tomcat的配置！！！配置文件的路径是tomcat/conf/server.xml,具体配置内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<Server port="16001" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.startup.VersionLoggerListener" />
<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
<Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
<Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
<GlobalNamingResources>
<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
</GlobalNamingResources>
<Service name="Catalina">
<Connector port="2001" protocol="org.apache.coyote.http11.Http11NioProtocol"
connectionTimeout="20000"
maxThreads="4000"
executor="tomcatThreadPool"
URIEncoding="UTF-8"
maxPostSize="-1"
maxParameterCount="-1"
redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.LockOutRealm">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
</Realm>
<Host name="localhost" appBase="webapps1"
unpackWARs="true" autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
<Context path="" docBase="D:\tomcat\webapps\blog" debug="0"/>
</Host>
</Engine>
</Service>
</Server>
三、重点提示：
1、path为空代表当前路径，docBase代表工程的具体路径，有时候docBase="blog"也行，但是会出现莫名其妙的问题，建议写成全路径的，切记！！！
<Context path="" docBase="D:\tomcat\webapps\blog" debug="0"/>
2、工程所在的目录不能和appBase的目录相同：如果blog的工程在webapps文件夹内，则appBase就不能配置成webapps，否者项目会启动两次，切记！！！
