java - 基于 Spring mvc 注解的 Controller RequestMappingHandlerMapping 有什么问题？

Question

我正在将我的一个应用程序从 Spring 工具套件 IDE 移植到纯 Eclipse Java EE IDE。在这个过程中，我正在重命名一些包并更改为基于 Maven。然后所有 Controller 都不再工作。

我认为注释 Controller 发现似乎已损坏。没有映射 url 注册到 Spring。

有人知道问题出在哪里吗？

我从我的 STS(工作)中收集旧日志，它工作正常并且喜欢

然后我从Eclipse中收集日志(问题一)

Answer 1

你的:

<context:component-scan base-package="old.package.name" />

现在应该是

<context:component-scan base-package="new.package.name" />
