问题 I have a working Spring application that contains a embedded Tomcat. As a executable war, it works fine. As I'm going to use AngularJ for the front end, it isn't very practical to have the Spring project in an executable jar, as I will do debugging in the browser and want to be able to quickly edit the js source files.
