Maven添加Tomcat插件实现热部署代码实例

<tomcat-users>
<!--
 NOTE: By default, no user is included in the "manager-gui" role required
 to operate the "/manager/html" web application. If you wish to use this app,
 you must define such a user - the username and password are arbitrary.

<!--
 NOTE: The sample user and role entries below are wrapped in a comment
 and thus are ignored when reading this file. Do not forget to remove
 <!.. ..> that surrounds them.
