如果webapp包含@Stateless ejb,我无法启动在websphere liberty profile 8.5.5上嵌入CODI的webapp。
我得到了这个例外:

我已经确定只有在项目中存在ejb时才会出现问题(在我的例子中是@Stateless ejb)。
在这种情况下,启动服务器并安装/部署webapp时,将初始化应用程序上下文。这里没问题。
当第一个HTTP请求由webapp处理时,FacesServlet
被初始化并且CodiNavigationHandler
被实例化。
在构造函数中调用方法CodiNavigationHandler.isAddViewConfigsAsNavigationCaseActivated()
并尝试获取CODI JsfModuleConfig
的引用。这个JsfModuleConfig
有一个@ApplicationScoped注释,beanManager试图获取应用程序上下文。
此应用程序上下文已经创建(部署webapp时),但尚未调用LibertyContextsService.initApplicationContext(String)
。
因此,LibertyContextsService.applicationContexts
ThreadLocal变量上的应用程序上下文为空,并发生错误:
WebBeans context with scope type annotation @ApplicationScoped does not exist within current thread
重现:
beans
元素)faces-config
元素)添加无状态bean:
import javax.annotation.PostConstruct;
import javax.ejb.Stateless;
@Stateless
public class MyBean {
@PostConstruct
public void postConstruct() {
System.out.println("post construct: " + this);
}
public String getTitle() {
return "test";
}
}
添加一个jsf bean:
import javax.inject.Inject;
import javax.inject.Named;
@Named
public class MyController {
@Inject
private MyBean myBean;
public String getTitle() {
return myBean.getTitle();
}
}
添加一个简单的jsf网页:
<h:body>
<h:outputText>${myController.title}</h:outputText>
</h:body>
nota :如果删除ejb上的@stateless,则应用程序可以正常工作。
答案 0 :(得分:1)
实际上它似乎是一个错误(我也在IBM论坛上发布了这个问题:https://www.ibm.com/developerworks/community/forums/html/topic?id=f372bbc5-5ba4-4c2a-9ef0-0bdcd76766da#09228314-2baf-4892-899e-5a8cc52daa19)。
我将尝试找到一种创建PMR的方法(我在一家大公司,很难找到合适的人来授予我访问权限)。
所以现在,我已经转向了jboss。
