Public String Createcourse () {
return "Course_admin/edit";
}

@RequestMapping (value= "/save", method = Requestmethod.post)

Public String Dosave (Course Course) {Original method

To complete the process of binding parameters @ModelAttribute the annotation of the method parameter level
Public String dosave (@ModelAttribute Course Course) {
Log information used to confirm the action
