The user is free to choose the third party's log component as a concrete implementation, like log4j, or the logging that comes with the JDK, common-logging will automatically find the log library that is actually used when the program runs by dynamic lookup mechanism. Of course, there is a simple logger implementation of common-logging inside, but the function is very weak. So

Foreword: Because of own responsibility project (jetty embedded launch of SPRINGMVC) need to implement file upload, and their own Java file upload this piece has not touched, and the Http protocol is more vague, so this time using a gradual way to learn the principle and practice of file upload.
