我正在使用带有spring 5，hibernate，primefaces 6.2和jsf 2.2的web应用程序，并使用CDI 2从jsf 2.2升级到jsf 2.3。我无法从FacesContext.getCurrentInstance（）获取sessionMap.getExternalContext（）。getSessionMap （）在CDI bean中，所以我正在尝试另一种方式。我试图在CDI-bean中注入@SessionMap（JSF 2.3的新功能）。
@Named("environmentManager")
@ViewScoped
public class EnvironmentManagerBacking implements Serializable {
@Inject
@SessionMap
private Map<String, Object> sessionMap;
..
}
但我收到错误消息＆＃34;找不到使用@ SessionMap＆＃34;的bean限定。如果我删除@Named的bean，它似乎没有错误消息。但我在jsf页面中将@Named用于EL表达式。
我不明白如何将JSF的CDI bean和sessionMap一起工作。在JSF 2.3中，我应该用cdi bean替换jsf托管bean。现在怎么办？
更新 ＆＃39; FacesContext.getCurrentInstance（）。getExternalContext（）。getSessionMap（）＆＃39;
