Question

我有一个maven项目作为一个宁静的设计，我将每一层分开：我有一个域层，数据层和一个Web层。我的问题是：每当我将域类（实体）添加到域层时，我的web层都不起作用，我得到404异常，仅此而已。我有三个项目。

1) domain_layer(All entities)
2) data_layer(All service and repositories)
3) web_layer(All controllers).

即使我使用命令：

mvn clean install eclipse:clean eclipse:eclipse

mvn clean package eclipse:clean eclipse:eclipse

也无效。

但是当我删除新课程时，它再次起作用。

任何人都知道这个问题吗？

这是我在网络层中的pom.xml：

Answer 1

解决了它。实体类中缺少@Id 每个Entity类都必须有一个@Id注释。

当我在Maven项目中添加对域层的任何调用时，我的Web层不起作用
