找不到对 http://localhost:8082/{params} 的观察者的请求

Question

我这里有一个非常简单的 Java REST 服务代码概念。

问题是，当我点击 URL 时，控制台中显示以下消息：找不到 http 的请求：//localhost:8082/REST/services/patientservices/getallpatients's Observer

我正在为 spring 使用cxf.jaxrs.component-scan=true来读取注释。

下面是类和配置文件：

pom.xml：

Answer 1

pom.xml文件中有错误。

它应该是jaxrs依赖而不是jaxws依赖。
