[英]OSGi REST service is not working (bnd tool)
我根據Amdatu指南編寫了一個REST服務,它非常簡單,但是卻拋出一個錯誤,我添加了所有依賴項,但仍然缺少需求錯誤
這是一條錯誤消息
! 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)))

Welcome to Apache Felix Gogo
g!
這是實現
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";
}
}
這是一個激活器類
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));
}
}
我添加了這些來建立依賴關系
這些是運行依賴
如果您要求我將Servlet軟件包更改為3.0,我將回答一些其他服務,要求Servlet
版本必須小於3.0,現在我無法同時滿足它們。
問題出在您的“運行包”配置中:
這兩個捆綁軟件也可以在“ Amdatu Dependencies”存儲庫中找到。
