OSGI：卡拉夫JAX-RS的CXF異常：沒有找到資源方法的資源

我在使用OSGI和Karaf創建簡單的CXF Web服務時收到異常。OSGI：卡拉夫JAX-RS的CXF異常：沒有找到資源方法的資源

真的很感激任何意見/建議的修復。

這是我跟我的項目和步驟的說明：下載了Apache Karaf-4.0.7

運行「MVN全新安裝」的路徑在命令行到我的項目

開始Karaf控制檯，並運行以下命令

 feature:repo-add cxf 3.1.8 
     feature:install cxf/3.1.8

接口：

public interface MyRestService { 
     String pingMe(String echo); 
    }

實現：

@Path("/") 
public class MyRestServiceImpl implements MyRestService { 

    @GET 
    @Path("/{echo}") 
    @Produces(MediaType.APPLICATION_XML) 
    public String pingMe(@PathParam("echo") String echo) { 
     return "Knock Knock: " + echo + " !!"; 
    } 
}

你能儘量不要使用接口，只需在類「MyRestServiceImpl」上創建REST實現和註釋;過去我們遇到了一些與interfcaes有關的問題，現在我們所有的REST服務都只在Classes中定義。 –

嘗試把JAX-RS註解服務接口上。

另一個可能的原因是註釋包未被導入。你在你的pom中阻止了很多進口。你可以檢查沒有這些定義。

我也嘗試過這種方式，但沒有多大幫助。得到了同樣的錯誤。謝謝@Christian Schneider。 – Sarav

@Sarav你在界面中添加了哪個註釋？看來JAX-RS對於你在那裏聲明的那個非常敏感。 –

@ruffp現在用下面的JAX-RS註釋的界面： – Sarav

在我的身邊你的代碼的作品，但我不得不改變了以下幾件事：從藍圖總線

刪除的實現類

更改導入部分@Path：

取出CXF在pom.xml

實現：

package com.mycompany.testcxf; 

import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.PathParam; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 

public class MyRestServiceImpl implements MyRestService { 

    @Override 
    @GET 
    @Path("/{echo}") 
    @Produces(MediaType.APPLICATION_XML) 
    public String pingMe(@PathParam("echo") String echo) { 
     return "Knock Knock: " + echo + " !!"; 
    } 
}

pom。XML：

<osgi.export.package>{local-packages}</osgi.export.package> 
<osgi.import.package> 
    com.mycompany.testcxf*, 
    * 
</osgi.import.package>

，我只進口的依賴：

<dependency> 
     <groupId>org.apache.cxf</groupId> 
     <artifactId>cxf-rt-frontend-jaxrs</artifactId> 
     <version>2.7.13</version> 
    </dependency>

注意我無法測試CXF版本3，你因爲我的OSGI容器被綁定到這個版本。然而，這個設置完全適合我，那麼它可能是CXF版本的問題，以及與嵌入式http服務器（Jetty？）的一些不兼容問題。

我的設置是ServiceMix 5.1.4有：

版本的Apache Karaf的2.3.9
版本駱駝
版本CXF

我想你建議的方式，但它拋出另一個錯誤說： org.osgi.service.blueprint.container.ComponentDefinitionException：元素裁判必須具有有效成分-id屬性謝謝@ruffp。 – Sarav

@sarav我更新了我的答案，它適用於我的設置。你可以試用cxf v3嗎？讓我知道嗎？ –
