大家好，又见面了，我是你们的朋友全栈君。
1、将项目打成WAR包放在Tomcat的webapps目录下
2、在Tomcat的安装目录的conf下找到server.xml的文件，如：D:\apache-tomcat-9.0.8\conf\server.xml
3、在Host标签里边添加
<Host name=”localhost” appBase=”webapps”
unpackWARs=”true” autoDeploy=”true”>
<!– SingleSignOn valve, share authentication between web applications
Documentation at: /docs/config/valve.html –>
<!–
<Valve className=”org.apache.catalina.authenticator.SingleSignOn” />
–>
<!– Access log processes all example.
Documentation at: /docs/config/valve.html
Note: The pattern used is equivalent to using pattern=”common” –>
<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=”myproject” reloadable=”true” />
</Host>
Context标签内容，注意path填空，docBase为项目名称
4、再次访问即可携带项目名称或不带都可以访问到项目。如localhost:8080/或localhost:8080/myproject
