1.如果你用4.1.18版(该版本是目前最稳定的版本)的tomcat。可以在http://127.0.0.1:8080/manager/html/ 对你的应用进行reload。2. reloadable (tomcat文档) Set to true if you want Catalina to monitor classes in /WEB-INF/classes/ and /WEB-INF/lib for changes, and automatically reload the web application if a change is detected. This feature is very useful during application development, but it requires significant runtime overhead and is not recommended for use on deployed production applications. You can use the Manager web application, however, to trigger reloads of deployed applications on demand.
