我的项目分为两个部分。第一部分是“ memberManagement-angular”，第二部分是“ memberManagemnt-service”。 对于memberManagement-angular，我有一个“ spring-mvc.xml”，对于mamberManagement-service，有一个“ sping-config.xml”。
spring-mvc.xml如下所示：
<?xml version="1.0" encoding="UTF-8"?>

spring-config.xml看起来像这样：

最后，我的memberManagement-service部分再次分为3个文件夹，分别为“ DAO”，“ Model”和“ Service”。
我确实有一个名为“ RoomController”的Controller类，其中包含一个“ RoomDAO”，“ Room”（模型类），“ RoomServiceImplementation”和“ RoomService”（RoomServiceImplementation的接口）。这完全可以正常工作。 因此，我为“成员”实现了具有相同内容（完全相同）的相同类。为此，我收到以下错误消息：
