凡是覺得的不科學的錯誤，99%是自己的粗心造成的，所以寫代碼的時候要細心，謹慎copy

想起了當年~~~加油哈

我特么，原來是包名寫錯了。
吃了文化的虧啊。。

配置是沒有問題的。

還有就是記得修改mybatis里mapper.xml文件里的路徑。

=================================================================
最開始只報了一個
警告: No mapping found for HTTP request with URI [/holy-spring/user/userInfo] in DispatcherServlet with name 'dispatcher'
我也找不到是哪里的問題，后來試著把controller換到可以映射到的controller的同一目錄下，報了另一個出錯
嚴重: Context initialization failed
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userController': Unsatisfied dependency expressed through field 'userService': No qualifying bean of type [line.moduls.user.service.UserService] found for dependency [line.moduls.user.service.UserService]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)};

才發(fā)現(xiàn)是包名拼錯了。
