帶有WildFly的JavaEE:找不到Rest資源-為什么?

[英]JavaEE with WildFly: Rest Resource not found - why?

我試圖在后台運行帶有WildFly-Application Server的簡單REST-Application。 但是REST-Call給我永久性的Not Found -Error。

這是我的RestService -class:

@Path("/rest")
public class RestService {


    @GET
    @Path("/hello")
    @Produces(MediaType.TEXT_PLAIN)
    public Response helloWorld() {

        try {
            System.out.println("ABCDEF");
            return Response.status(Response.Status.OK).entity("hello world!").build();
        } catch (Throwable throwable) {
            return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity(throwable).build();
        }
    }
}

使用Rest-Configuration-File:

@ApplicationPath("/")
public class JaxRsActivator extends Application {
}

這是我的配置文件:

pom.xml:

                <version>3.2.0</version>
            </plugin>
        </plugins>
    </build>

web.xml:

         version="2.5">
    <display-name>REST</display-name>
</web-app>

jboss-web.xml:

<jboss-web>
    <context-root>services</context-root>
</jboss-web>

和我的項目結構:

在此處輸入圖片說明

我想通過以下網址調用我的Rest-Service:

http://127.0.0.1:8080/services/rest/hello

但這會導致未找到錯誤-這是什么問題?

我發現了錯誤:

項目結構錯誤:它必須是web而不是webapp
