在Jersey中找不到符号PathParam

Question

这是我的代码

@Path("/users/{id}")
public class MyResource {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getId(@PathParam("id") String id) {
        return "Getting Messages for User : " + id;
    }
}

我得到的只是

..MyResource.java:[17,29] error: cannot find symbol

到目前为止，我已经检查了这个 https://confluence.atlassian.com/display/CLOVERKB/Maven 2 插件失败，在为源文件定义两个位置时找不到符号异常

maven“找不到符号”消息没有帮助

但是没有任何成功。

编辑：pom.xml

我在你的链接中看到了你的pom.xml，看起来你使用了我熟悉的Maven原型。您发布的代码是原型提供的唯一类。唯一不同的是，您添加了< code>@PathParam(以及路径的更改)。在这种情况下，您仍然需要导入注释:-)

import javax.ws.rs.PathParam;
