嵌入式码头：没有发生依赖注入

如何解决嵌入式码头：没有发生依赖注入

为长篇文章道歉。不知道什么时候太多了。问题是在 Jersey REST servlet 上没有发生依赖注入。根据产品设计师的要求使用嵌入式 Jetty 和 REST。 这是我拥有的一些代码：

AppServer.java

Configuration.ClassList classList = Configuration.ClassList.setServerDefault(server);
classList.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration","org.eclipse.jetty.plus.webapp.EnvConfiguration","org.eclipse.jetty.plus.webapp.PlusConfiguration");
classList.addBefore("org.eclipse.jetty.webapp.JettyWebXmlConfiguration","org.eclipse.jetty.annotations.AnnotationConfiguration");

ServletContextHandler servletCtx = new ServletContextHandler(ServletContextHandler.SESSIONS);
servletCtx.setContextPath("/rest/v1");
ServletHolder jerseyServlet = servletCtx.addServlet(
        org.glassfish.jersey.servlet.ServletContainer.class,"/*");
jerseyServlet.setInitOrder(0);

jerseyServlet.setInitParameter(
        "jersey.config.server.provider.classnames",MbiResource.class.getCanonicalName());

WebAppContext webAppCtx = new WebAppContext();
webAppCtx.setResourceBase("webapp");
webAppCtx.setContextPath("/");

HandlerList handlers = new HandlerList();
handlers.setHandlers(new Handler[]{servletCtx,webAppCtx,new DefaultHandler()});

server.setHandler(handlers);

RestResource.java

import org.apache.tomcat.jdbc.pool.DataSource;

import javax.annotation.Resource;
import javax.json.JsonObject;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("mbi")
@Consumes({MediaType.TEXT_PLAIN,MediaType.APPLICATION_JSON})
@Produces({MediaType.TEXT_PLAIN,MediaType.APPLICATION_JSON})
public class MbiResource {
    **//this does not work**
    @Resource(mappedName = "jdbc/warehouse-datasource")
    DataSource dataSource;

    @GET
    public String get(){
    **//this does work**
        try{
            InitialContext ic = new InitialContext();
            dataSource = (DataSource) ic.lookup("jdbc/warehouse-datasource");
            return dataSource.toString();
        }catch (Exception ex){
            return ex.getMessage();
        }
    }
}

POM（所有依赖的原因是强制同一个版本）
