Веб-сервисы CXF с OSGI и Karaf

Я пытаюсь создать простой веб-сервис с OSGI и Karaf.

Вот шаги, которые я проделал:

  1. скачать апач караф - 3.0.3
  2. запустите karaf, выполните следующие команды
  3. особенность: репо-добавить cxf 3.0.
  4. особенность: установить http cxf

Затем создал следующие классы:

интерфейс

  public interface IMyService {
    String sayHello(
            String name);
    }

выполнение

@WebService
public class MyServiceImpl implements IMyService {

    @Override
    public String sayHello(
            final String name) {
        return "Hello " + name + " !!";
    }
}

Схема OSGI.xml

 <cxf:bus id="cxfBus1">
        <cxf:features>
            <cxf:logging />
        </cxf:features>
    </cxf:bus>
    <jaxrs:server address="/hello" id="helloService">
        <jaxrs:serviceBeans>
            <ref component-id="helloBean" />
        </jaxrs:serviceBeans>
    </jaxrs:server>
    <bean id="helloBean" class="org.test.ws.impl.MyServiceImpl" />

Когда пакет развернут в каталоге karaf deploy, пакет не может быть установлен. Возникает следующая ошибка:

Для веб-службы RESTful вам понадобится такой план:

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.1.0"
           xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
           xmlns:cxf="http://cxf.apache.org/blueprint/core"
           xmlns:jaxrs="http://cxf.apache.org/blueprint/jaxrs"
           xsi:schemaLocation="
  http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
  http://www.osgi.org/xmlns/blueprint-ext/v1.1.0 https://svn.apache.org/repos/asf/aries/tags/blueprint-0.3.1/blueprint-core/src/main/resources/org/apache/aries/blueprint/ext/blueprint-ext.xsd
  http://cxf.apache.org/blueprint/jaxws http://cxf.apache.org/schemas/blueprint/jaxws.xsd
  http://cxf.apache.org/blueprint/jaxrs http://cxf.apache.org/schemas/blueprint/jaxrs.xsd
  http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd
  http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd
  http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0 http://aries.apache.org/schemas/blueprint-cm/blueprint-cm-1.1.0.xsd
  http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.1.0 http://aries.apache.org/schemas/blueprint-ext/blueprint-ext-1.1.xsd
  ">
    <cxf:bus id="myServiceBus">
    </cxf:bus>

    <bean id="myServiceImpl" class="org.test.ws.impl.MyServiceImpl"/>

    <jaxrs:server address="/hello" id="helloService">
        <jaxrs:serviceBeans>
            <ref component-id="myServiceImpl" />
        </jaxrs:serviceBeans>
        <jaxrs:providers>
        </jaxrs:providers>
    </jaxrs:server>

</blueprint>

Затем вам нужно удалить аннотацию @WebService и использовать аннотации javax.ws.rs.*, чтобы определить метод HTTP, который вы хотите использовать для каждой опубликованной службы RESTful, например:

public class MyServiceImpl implements IMyService {

    @GET
    @Path("/{name}")
    @Produces(MediaType.APPLICATION_XML)
    public String sayHello(@PathParam("name") final String name) {
        return "Hello " + name + " !!";
    }
}

В этой конфигурации вы можете вызывать службу RESTful как: http://hostname:8181/cxf/hello/MYNAME< /а>

Надеюсь, теперь это поможет...

Кстати, в моем pom.xml есть эти зависимости:

    <dependency>
        <groupId>javax.ws.rs</groupId>
        <artifactId>jsr311-api</artifactId>
        <version>1.1.1</version>
    </dependency>

    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxrs</artifactId>
        <version>${cxf.version}</version>
    </dependency>

    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-transports-http</artifactId>
        <version>${cxf.version}</version>
    </dependency>

    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-transports-http-jetty</artifactId>
        <version>${cxf.version}</version>
    </dependency>

Вам нужно два изменения:

1- Измените свой импл как:

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

@Path("/myService")
public class MyServiceImpl implements IMyService {

    @GET
    @Path("/sayHello")
    @Produces(MediaType.APPLICATION_XML)

    @Override
    public String sayHello(final String name) {
        return "Hello " + name + " !!";
    }
}

2- добавьте зависимость cxf-rt-frontend-jaxrs в ваш файл pom.xml:

    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxrs</artifactId>
        <version>3.0.2</version>
    </dependency>

Для WebService вам нужно использовать jaxws.

Попробуйте с этим планом:

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.1.0"
    xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
    xmlns:cxf="http://cxf.apache.org/blueprint/core"
    xmlns:jaxws="http://cxf.apache.org/blueprint/jaxws"
    xsi:schemaLocation="
  http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd

    <cxf:bus id="myServiceBus">
    </cxf:bus>

    <bean id="myServiceImpl" class="org.test.ws.impl.MyServiceImpl"/>

    <jaxws:endpoint
            implementor="#myServiceImpl"
            address="/hello"

Нет, я не хочу JAX-WS. Мне нужны веб-сервисы RESTful (JAX-RS). - person grozandrei; 02.06.2015

@JorgeMartinez, у вас есть пример использования JAX-WS для демонстрации реализаций OSGi? - person Twimnox; 17.11.2016
