OSGI：使用Karaf JAX-RS的CXF异常：没有找到资源的资源方法

时间：2017-01-06 21:04:19

标签： rest jax-rs osgi cxf apache-karaf

我在使用OSGI和Karaf创建简单的CXF Web服务时遇到异常。

非常感谢任何有关修复的意见/建议。

以下是我的项目说明和我遵循的步骤：

  1. 下载了Apache Karaf-4.0.7
  2. 在命令行中使用项目路径
    3. 运行“mvn clean install”

  3. 启动Karaf控制台，并运行以下命令

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

    4. 接口：

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

    实现：

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

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

尝试将jax-rs注释放在服务接口上。

另一个可能的原因是未导入注释包。你阻止了你的pom中的大量进口。你可以检查没有这些定义。

在我这边你的代码可以工作，但我不得不改变以下事项：

  1. 从蓝图中删除cxf：bus
  2. 删除实现类<{li>上的@Path
  3. 更改pom.xml
    4. 中的导入部分

    实现：

    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 + " !!";
    }
}

    的pom.xml：

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

    我只导入依赖项：

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

    注意我无法像您一样测试CXF版本3，因为我的OSGI容器已绑定到此版本。但是这个设置对我来说非常合适，那么它可能是CXF版本的一个问题，并且与嵌入式http服务器（Jetty？）有些不兼容。

    我的设置为ServiceMix 5.1.4，其中包含：

    • Apache Karaf版本2.3.9
    • Camel版本2.13.3
    • CXF版本2.7.13
