CDI : WFLYWELD0044:将资源注入javax.servlet.ServletException托管bean时出错。找不到名为的资源。。

Question

错误发生在WildFly 10容器中。整个错误看起来像这样：

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
at java.lang.Thread.run(Thread.java:745)
Caused by: javax.naming.NameNotFoundException: env/com.maggioni.Bean.InfoBean/infoCreator -- service jboss.naming.context.java.module.B77.EJBStatefulBean-Bidder-Demo-web.env."com.maggioni.Bean.InfoBean".infoCreator

[0m[31m13:45:26,716 ERROR [io.undertow.request] (default task-8) UT005023: Exception handling request to /web/infobean.jsf: javax.servlet.ServletException: WFLYWELD0044: Error injecting resource into CDI managed bean. Can't find a resource named java:comp/env/com.maggioni.Bean.InfoBean/infoCreator

Infobean.jsf注入如下所示：

@Named("infobean")
@SessionScoped
public class InfoBean implements Serializable{     
    private static final long serialVersionUID = 1L;

    @EJB
    private InfoCreator infoCreator;

    public String getInfo() {
        return infoCreator.getInfo();
    }
}

EJB信息生成器看起来像这样

@Stateful 
public class InfoCreator implements InfoInterface{

    @Override
    public String getInfo() {
       return "Info";
    }
}

如果你想知道更多细节，请让我知道，我真的不太确定需要在这里张贴什么。

首先，为什么要将有状态EJB注入到CDI bean中？鉴于您发布的代码，我认为没有任何理由使用EJB (对于有状态的EJB更是如此)。

只需移除@Stateful注释并像这样注入它：

@Named("infobean")
@SessionScoped
public class InfoBean implements Serializable{     
    private static final long serialVersionUID = 1L;

    @Inject
    private InfoCreator infoCreator;

    public String getInfo() {
        return infoCreator.getInfo();
    }
}
