Jetty + Jersey Servlet + Weld:焊缝注射未初始化，怎么了? [英] Jetty+Jersey servlet+Weld: Weld injection not initialized, what is wrong?

问题描述

我正试图从Glassfish + Jersey + Weld迁移到Jetty.

我有这样的设置: pom.xml，web.xml和Java启动器的要领.

应用程序似乎可以正常启动，但是在处理任何请求时，我看到应该由Weld(logger)注入的字段为空.

@RequestScoped
@Path("/foobar")
@Consumes({ ExtendedMediaType.APPLICATION_JSON, 
    ExtendedMediaType.APPLICATION_JAVASCRIPT })
@Produces({ ExtendedMediaType.APPLICATION_JSON, 
    ExtendedMediaType.APPLICATION_JAVASCRIPT })
public class EmailResource extends {

    @Inject
    private Logger logger;

    @Override @POST
    public Response create(EmailJob document) 
        throws URISyntaxException, ResourceException 
    {
       logger.debug("Hi there!");
    }
}

出什么问题了?

更新:Logger生产者看起来可疑，但甚至没有得到称呼:

/** This class uses CDI to alias Java EE resources into CDI beans. **/
public class Resources {

    @Produces
    public Logger produceLog(InjectionPoint injectionPoint) {
        return LoggerFactory.getLogger(
            injectionPoint.getMember().getDeclaringClass().getName());
    }
}

解决方案

维克多，我的要求是我的要求，我已经 github . /p>

我的主旨没有发现任何问题，但是您可以显示Logger生产者吗?

更新:

我在您的代码中看到一个错字"BeanMnanager"，但不确定是否是原因

new Resource("BeanManager", new Reference("javax.enterprise.inject.spi.BeanMnanager",
        "org.jboss.weld.resources.ManagerObjectFactory", null));

I'm trying to migrate from Glassfish+Jersey+Weld to Jetty.

I have such a setup: gist of pom.xml, web.xml and Java launcher.

Application seems to start fine, but when serving any request I see that the field that should be injected by Weld (logger) is null.

@RequestScoped
@Path("/foobar")
@Consumes({ ExtendedMediaType.APPLICATION_JSON, 
    ExtendedMediaType.APPLICATION_JAVASCRIPT })
@Produces({ ExtendedMediaType.APPLICATION_JSON, 
    ExtendedMediaType.APPLICATION_JAVASCRIPT })
public class EmailResource extends {

    @Inject
    private Logger logger;

    @Override @POST
    public Response create(EmailJob document) 
        throws URISyntaxException, ResourceException 
    {
       logger.debug("Hi there!");
    }
}

What is the problem?

update: Logger producer looks dubious, but it doesn't even get called:

/** This class uses CDI to alias Java EE resources into CDI beans. **/
public class Resources {

    @Produces
    public Logger produceLog(InjectionPoint injectionPoint) {
        return LoggerFactory.getLogger(
            injectionPoint.getMember().getDeclaringClass().getName());
    }
}

解决方案

Hi Victor my answer as requested, I've blogged about this with embedded jetty. I've also pushed a fully working example to github that you can clone.

I don't see anything wrong in your gist, however could you show your Logger producer?

UPDATE:

I see a typo "BeanMnanager" in your code, but not sure if it is the cause

new Resource("BeanManager", new Reference("javax.enterprise.inject.spi.BeanMnanager",
        "org.jboss.weld.resources.ManagerObjectFactory", null));
