Primefaces WELD-001303:在Websphere上没有作用域类型javax.enterprise.context.sessionScope的活动上下文

我们已经将应用程序升级为使用CDIBeans。当我们在Wildfly 10.x上部署应用程序时，这一变化非常顺利，但当我们尝试在WebSphereClassic和Liberty上部署相同的应用程序时，出现了一些问题

我们已经在这里找到了几个问题，比如，或者，但是没有一个答案能够解决我们的问题

在我的本地主机上，我将WebSphereLiberty配置文件与webProfile-7.0一起使用，这意味着CDI-1.2、EL-3.0、JSF-2.2和servlet-3.1。 我们的应用程序还使用Primefaces 6.0

该问题发生在相位侦听器上。在它上面，我们正在注入一个Bean，该Bean带有

@Named

（javax.inject.Named）和

@SessionScoped

（javax.enterprise.context.SessionScoped）注释

在phaseListener上调用注入变量时，会引发以下错误

下面是我们希望注入的会话范围bean

@Named("ws")
@SessionScoped
public class WebSession extends LoggableBean {
    private static final long serialVersionUID = 5L;

    @Inject
    protected WebApplication wa;

    /** True if session originates from a trusted logon */
    private boolean trusted = false;

    /**
     * Current user, null if not logged in (this may be a simulated user token if {@link #simulateUser(int)} was called
     * before.
     */
    private ISofTokenType userToken;

    /**
     * Original login user (identical to userToken if not simulating another user
     */
    private ISofTokenType loginUserToken;

    /** Current locale of the websession. */
    private Locale locale;

    /** The policy rules resolver for this session */
    private transient PolicyResolver policy;

    @Inject
    protected Config config;

    @Inject
    protected WebPaths path;

    @Inject
    protected WebApplicationStore waStore;

    @PostConstruct
    protected void init() {
        try {
            setLocale(LocaleUtils.getDefaultLanguage().getCode());
        } catch (ConfigurationException ex) {
            // Fallback to default language in config.xml
            getLog().error(ex);
            locale = FacesContext.getCurrentInstance().getApplication().getDefaultLocale();
        }
    }

    /**
     * Check if the currentRelease session is linked with a logged in user or if the visitor is a guest.

     */
    public boolean isLoggedIn() {
        return userToken != null;
    }
}

这是phaseListener

public class PolicyController implements PhaseListener {
    private static final long serialVersionUID = 2189917635371117541L;

    private static final Log log = LogFactory.getLog(PolicyController.class);
    private static final String VALIDATION_ERROR_DEFAULT_KEY = "validation_error_default";
    private static final String COMPONENT_ATTRIBUTE_RENDERED_MODIFIED_BY_RULE = "rendered-modified-by-policy";

    private static enum PhaseMoment {
        BEFORE, AFTER
    };

    @Inject
    private WebSession ws;

    public void beforePhase(PhaseEvent event) {
        if (!FacesHelper.getConfig().getBoolean(Properties.POLICY_CONTROLLER_ENABLED, true)) {
            if (event.getPhaseId() == PhaseId.RENDER_RESPONSE) log.debug("Policy is disabled");
            return;
        }

        if ((event.getPhaseId() == PhaseId.RENDER_RESPONSE || event.getPhaseId() == PhaseId.PROCESS_VALIDATIONS)
                && ws.isLoggedIn()) { // <- Error happens here
            // Apply the rules...
            FacesContext fc = event.getFacesContext();
            log.debug("Run PolicyController before " + event.getPhaseId() + " (viewroot has "
                    + fc.getViewRoot().getChildCount() + " direct children)");
            traverseComponent(fc, fc.getViewRoot(), event.getPhaseId(), PhaseMoment.BEFORE);
        }
    }

    public void afterPhase(PhaseEvent event) {
        if (!FacesHelper.getConfig().getBoolean(Properties.POLICY_CONTROLLER_ENABLED, true)) {
            return;
        }

        if ((event.getPhaseId() == PhaseId.PROCESS_VALIDATIONS || event.getPhaseId() == PhaseId.RESTORE_VIEW)
                && ws.isLoggedIn()) { // <- Error happens here
            FacesContext fc = event.getFacesContext();
            log.debug("Run PolicyController after " + event.getPhaseId() + " (viewroot has "
                    + fc.getViewRoot().getChildCount() + " direct children)");
            traverseComponent(fc, fc.getViewRoot(), event.getPhaseId(), PhaseMoment.AFTER);
        }
    }
}

在if语句之前，使用webSession而不是ws，但得到了相同的错误

我想再次指出，这在Wildfly中运行良好，这导致我们假设我们正确地实现了代码。此外，我们确信我们使用的是Java8，服务器支持JEE7，因此，从我们所看到的所有地方来看，我们都认为这应该是我们的Websphere版本所支持的。 在WebSphereClassic9.0上部署应用程序时，我们遇到了完全相同的问题

到目前为止，我们发现的唯一区别是Websphere使用Myfaces，而Wildfly使用Mojara。这可能是我脸上的某种缺陷吗？我们是否需要使用任何特定的配置或代码来支持这类事情

---

如果您需要有关我们的实现的更多信息来帮助找出原因，请告诉我。

跟进这个问题已经晚了4年，但是，如果其他人发现了，应该在WebSphere上将解决方案设置为DelferServletRequestListenerDestroyonerror

因此，如果您在Liberty上，只需在server.xml上执行以下操作：

---

您能发布来自phaseListener和@SessionScoped bean的相关代码吗？在原始文本中添加了与问题相关的代码。Websphere Liberty 19.0中也存在同样的问题。还注意到这可能是由于myfaces，因为Wildfly正在使用Mojarra。

FacesContext context = event.getFacesContext();
WebSession webSession = context.getApplication().evaluateExpressionGet(context, "#{ws}", WebSession.class);
