mysql - Spring 框架 RESTful 服务

Question

我正在 Eclipse 上构建我的第一个 Spring RESTful API。我无法调用 API。我得到“请求的资源不可用”。使用 http://localhost:8080/InterVUEService/api/Clinic/7 时出错.

你能告诉我为什么我不能调用http://localhost:8080/api/Clinic/id吗？ ？为什么这个 Uri 不能在我的 Tomcat 服务器上运行？请帮忙。我是一个新手，正在学习为我的下一个工作项目编写 Restful 服务以在 AWS 上托管。

谢谢纳利尼

Answer 1

<context:component-scan base-package="com.abaxis.interVUEservice.*dao"/>

你能试试改成

<context:component-scan  base-package="com.abaxis.interVUEservice" />

并使用http://localhost:8080/InterVUEService/api/Clinic/7
