在泽西岛找不到符号 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，我已经检查了这两个 https://confluence.atlassian.com/display/CLOVERKB/Maven+2+plugin+fails+with+cannot+find+symbol+exception+when+defining+two+locations+for+source+files

&这个

maven "cannot find symbol" message unhelpful

但没有任何成功。

我在您的链接中查看您的 pom.xml，看起来您正在使用我熟悉的 Maven 原型。您发布的代码是原型提供的唯一类。唯一的区别是，您添加了@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;
