OSGi REST服务无法正常运行（BND工具）

Question

我根据Amdatu指南编写了一个REST服务，它非常简单，但是却抛出一个错误，我添加了所有依赖项，但仍然缺少需求错误

这是一条错误消息

! could not resolve the bundles
! Failed to start bundle org.apache.felix.http.whiteboard-2.3.0, exception Unresolved constraint in bundle org.apache.felix.http.whiteboard [13]: Unable to resolve 13.0: missing requirement [13.0] osgi.wiring.package; (&(osgi.wiring.package=javax.servlet)(version>=3.0.0)(!(version>=4.0.0)))

g! 

这是实现

package web.rest;

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

@Path("hellorest")
public class HelloWorldResource {
    @GET
    @Produces(MediaType.TEXT_HTML)
    public String say_hello() {
        return "hello";
    }

}

这是一个激活器类

package web.rest;

import org.apache.felix.dm.DependencyActivatorBase;
import org.apache.felix.dm.DependencyManager;
import org.osgi.framework.BundleContext;

public class Activator extends DependencyActivatorBase{

    @Override
    public void destroy(BundleContext arg0, DependencyManager arg1)
            throws Exception {
        // TODO Auto-generated method stub

    }

    @Override
    public void init(BundleContext arg0, DependencyManager manager)
            throws Exception {
        manager.add(createComponent()
                .setInterface(Object.class.getName(),null)
                .setImplementation(HelloWorldResource.class));
    }

}

我添加了这些来建立依赖关系

这些是运行依赖

如果您要求我将Servlet软件包更改为3.0，我将回答一些其他服务，要求Servlet版本必须小于3.0，现在我无法同时满足它们。

Answer 1

问题出在您的“运行包”配置中：

1. 用org.apache.felix.http.servlet-api替换javax.servlet捆绑包。 它包含相应版本的javax.servlet包。
2. 还要添加jackson-jaxrs捆绑包

这两个捆绑软件也可以在“ Amdatu Dependencies”存储库中找到。
