标签: java eclipse rest osgi-bundle amdatu

我正在根据 Amdatu 指南编写一个REST服务,它非常简单但它给我一个错误我添加了所有依赖项但仍然缺少需求错误

这是错误消息

! 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! 

以下是实施

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Activator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));
    }

}

我已添加这些内容以构建依赖项 enter image description here

这些是“运行依赖项” enter image description here

如果您要求我将Servlet包更改为3.0,我将回答其他一些服务需要Servlet版本必须小于3.0现在我无法同时满足它们。

问题出在你的'run bundles'配置中:

  1. org.apache.felix.http.servlet-api 替换 javax.servlet 包。它包含适当版本​​的javax.servlet包。
  2. 同时添加 jackson-jaxrs 捆绑包
  3. 这两个捆绑包也可以在'Amdatu Dependencies'存储库中找到。
