A casual setting that triggers a night of "murder"

Bitter force programmer to build a spring MVC shelf, then take a few minutes to finish (about 19 o'clock more), error, 404, the request point path does not exist, a variety of Baidu, various configurations, a variety of other items of the configuration of direct copy, a variety of debugging, the result of this error:

No mapping found for HTTP request with URI

Finally abandon the @annotaiton way, directly write beans, and the result of a class not found abnormal, instantly think of a few days a base b setting:

The settings for the Auto build project have been canceled (it is now more than 23 points). I've got a lot of eggs in my stomach.

In fact, often brewing wrong is not what the principle of the problem, is a you careless, casual, do not care about the small place.
