web-services - 从 cxf Web 服务访问托管 bean

Question

@WebService(endpointInterface = "login")
public class LoginService{
 loginCredentials.login();
 }

公共类登录凭据{

@ManagedProperty(name = "applicationBD", value = "#{applicationBD}")
private IApplication applicationBD; //This class is application scoped

    How to access applicationBD in this layer?  

     //facescontext is null while calling this service from SOAP UI
    ServletContext servletContext = (ServletContext)FacesContext.getCurrentInstance().getExternalContext()
            .getContext();
    servletContext.getAttribute("applicationStartupBD");
}

我不相信你想做的是明智的，最好的设计。甚至是合法的:)。您可以ServletContext从以WebServiceContext

1. 将引用注入WebServiceContext到您的 SIB

   @Resource
   WebServiceContext ctxt;
   

2. 从 中WebServiceContext，检索MessageContext（比之前的上下文更接近于 Web 服务的 SOAP 负载处理结构）。从此，您将获得ServletContext

   MessageContext msgContext = ctxt.getMessageContext();
   ServletContext servletContext = (ServletContext)msgContext.get(MessageContext.SERVLET_CONTEXT);
   IApplication app = (IApplication)  servletContext.getAttribute("applicationStartupBD"); //You can do whatever you please at this point
   

这是推荐的方法吗？不，您已切换依赖项。webapp 应该依赖于 web 服务，而不是相反。IMO，webapp 更容易发生变化，并且是堆栈中的第一层。我建议您坚持两层之间的松散耦合
