资源类

public class UploadFileService {

    @Inject public Logger logger;

    @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(
        @FormDataParam("file") InputStream uploadedInputStream,
        @FormDataParam("file") FormDataContentDisposition fileDetail) {
    }
}

注入:: Logger类

@Dependent
public final class Loggers {

    @Produces
    public static final Logger getLogger(final InjectionPoint injectionPoint) {
    if (injectionPoint == null) {
        throw new IllegalArgumentException("injectionPoint", new NullPointerException("injectionPoint"));
    }
}

注入完美适用于包含beans.xml

*的.war\WEB-INF \类\ META-INF\beans.xml中

但是它不是在泽西2.0中可选的beans.xml吗？

缺少beans.xml时报告错误
