Karaf, cxf and jax-rs - No services have been found

问题

当我安装并启动捆绑包时，没有任何反应，控制台没有输出，而bundle:list报告它为"Active"。我尝试使用blueprint-web特性，但在日志中出现了"未找到资源类"的异常。

我的设置：

  • jdk 11
  • karaf 4.4.3
  • cxf 3.3.5
  • feature:install cxf http
  1. <dependencies>
  2.    <dependency>
  3.       <groupId>org.apache.cxf</groupId>
  4.       <artifactId>cxf-rt-frontend-jaxrs</artifactId>
  5.       <version>${cxf.version}</version>
  6.    </dependency>
  7.    <dependency>
  8.       <groupId>javax.ws.rs</groupId>

  26.       <version>${cxf.version}</version>
  27.    </dependency>
  28. </dependencies>

我使用的是Maven捆绑插件：

  1. <plugin>
  2.       <artifactId>maven-bundle-plugin</artifactId>
  3.       <extensions>true</extensions>
  4.       <configuration>
  5.          <instructions>
  6.             <Embed-Dependency>*;scope=compile|runtime;inline=false;artifactId=*</Embed-Dependency>
  7.             <Embed-Transitive>true</Embed-Transitive>
  8.             <Bundle-SymbolicName>${pom.groupId}.${pom.artifactId}</Bundle-SymbolicName>
  9.             <Bundle-Name>${pom.name}</Bundle-Name>
  10.             <Bundle-Version>${pom.version}</Bundle-Version>
  11.             <Export-Package>my.base.package.*</Export-Package>
  12.             <Import-Package>javax.ws.rs.*
  13.                             javax.jws.*
  14.                             *
  15.             </Import-Package>
  16.          </instructions>
  17.       </configuration>
  18.    </plugin>

OSGI-INF/blueprint.xml:

  1.     <cxf:bus>
  2.         <cxf:features>
  3.             <cxf:logging/>
  4.         </cxf:features>
  5.     </cxf:bus>
  7.     <jaxrs:server id="myService" address="/test">
  8.         <jaxrs:serviceBeans>
  9.             <ref component-id="myServiceBean" />
  10.         </jaxrs:serviceBeans>
  11.     </jaxrs:server>
  13.     <bean id="myServiceBean" class="my.base.package.impl.MyServiceImpl"/>

MyServiceImpl.java

  1. @Path("/")
  2. public class MyServiceImpl implements MyService{
  3.     public AccountStorageServiceImpl() {
  4.         System.out.println("MyService starting...");
  5.     }
  7.     @Path("/hello")
  8.     @GET
  9.     @Produces(MediaType.APPLICATION_JSON)
  10.     @Override
  11.     public String hello() {
  12.         return "Hello World!"
  13.     }
  14. }

我最初在接口中使用了注解，但移动到实现类后希望能有所帮助（但没有）。是否有一些我遗漏的额外配置/特性？

英文:

When I install and start the bundle, nothing happens, no output to the console and bundle:list reports it as "Active". I've tried using blueprint-web feature and I was getting No resource classes found exception in logs.

  13.     <bean id="myServiceBean" class="my.base.package.impl.MyServiceImpl"/>

MyServiceImpl.java

  1. @Path("/")
  2. public class MyServiceImpl implements MyService{
  3.     public AccountStorageServiceImpl() {
  4.         System.out.println("MyService starting...");
  5.     }
  7.     @Path("/hello")
  8.     @GET
  9.     @Produces(MediaType.APPLICATION_JSON)
  10.     @Override
  11.     public String hello() {
  12.         return "Hello World!";
  13.     }
  14. }

I had annotations in the interface at first but moved to the impl class hoping it would help(it didn't).
Is there some additional configuration/feature that I'm missing?

"Only one dependency is required:" -> "只需要一个依赖项："

"And the annotations can be on the interface, should also add annotation @Resource for it to get picked up by cxf:" -> "注解可以在接口上，还应该添加@Resource注解以供cxf识别："

英文:

As is turns out, project setup is not as hard as it seemed to be.
Only one dependency is required:

  1.         <dependency>
  2.             <groupId>org.apache.cxf</groupId>
  3.             <artifactId>cxf-rt-frontend-jaxrs</artifactId>
  4.             <version>${cxf.version}</version>
  5.             <scope>compile</scope>
  6.         </dependency>

And the annotations can be on the interface, should also add annotation @Resource for it to get picked up by cxf:

  1. @Resource
  2. @Path("/")
  3. public interface MyService {
  4.     @Path("/hello")
  5.     @GET
  6.     @Produces(MediaType.APPLICATION_JSON)
  7.     String hello();
  8. }

(annotations should be from javax.*)

Complete setup in case someone stumbles upon this question:

  1. feature:repo-add cxf
  2. feature:install cxf blueprint-web
  3. bundle:install {bundle}
  4. bundle:start {bundle-number}

Complete maven-bundle plugin config:

  1. <plugin>
  2.    <groupId>org.apache.felix</groupId>
  3.    <artifactId>maven-bundle-plugin</artifactId>
  4.    <version>5.1.9</version>
  5.    <extensions>true</extensions>
  6.    <configuration>
  7.       <instructions>
  8.          <Embed-Dependency>*;scope=compile|runtime;inline=false;artifactId=*</Embed-Dependency>
  9.          <Embed-Transitive>false</Embed-Transitive>
  10.          <Bundle-SymbolicName>${pom.groupId}.${pom.artifactId}</Bundle-SymbolicName>
  11.          <Bundle-Name>${pom.name}</Bundle-Name>
  12.          <Bundle-Version>${pom.version}</Bundle-Version>
  13.          <Export-Package>my.package.*</Export-Package>
  14.          <Import-Package>*</Import-Package>

  16.    </configuration>
  17. </plugin>
