CDI 不能注入 pojo java 类。 （带有限定符 @Default 的 Pojo 类型的不满意依赖项）

Question

Hi i have a problem with inject a regular java class (Pojo class) into EJB bean.

@ApplicationScoped
public class DomainRouteFinderService {

    @Inject
    private Pojo pojo;

    private AtomicInteger sequencer;

    @PostConstruct
    private void init(){
        sequencer = new AtomicInteger();
        sequencer.lazySet(0);
    }

    @Produces
    @Named("sequencer")
    public String getText(){
        return "Number: "+ sequencer.getAndIncrement();
    }
}

Pojo class:

public class Pojo {
}

In my multiprojects with structure like below:

ROOT - ear

1. ejb
2. web

Web module depends on ejb.

In web module is beans.xml with bean-discovery-mode="all"

Answer 1

I resolved my problem by adding another beans.xml to ejb. I put this file to main/java/resources/META-INF localization.

Why?

One of the most significant changes in CD 1.1/Java EE 7 is that by popular request, CDI is now enabled by default. This means that there's no need to explicitly add a beans.xml to enable DI any more. However, it is also very important to understand that CDI now also provides finer grained control over component scanning via the 'bean-discovery-mode' attribute. This attribute has three possible values:

 'annotated' - loosely translated, means that only components with a class-level annotation are processed. 'all' - all components are processed, just like they were in Java EE 6 with the explicit beans.xml. 'none' - CDI is effectively disabled.

By default, if you specify nothing and there is no beans.xml, the bean discovery mode of 'annotated' and not 'all' is assumed.

But i want to one beans.xml for ejb module and war module.
