看来这是正确的配置。注意不要将角色与空格分开！
<?xml version="1.0" encoding="UTF-8"?><tomcat-users> <role rolename="manager-gui"/> <role rolename="manager-script"/> <role rolename="manager-jmx"/> <role rolename="manager-status"/> <role rolename="admin-gui"/> <role rolename="admin-script"/> <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-gui,admin-script"/></tomcat-users>
