获取自定义春季范围

Question

我写的FacesContext Logique定制的春季范围的基极电流的要求，

public class DynamicScope implements Scope{ 
    @Override 
    public Object get(String name, ObjectFactory<?> objectFactory) { 
     AbsErpFolder erpFolder = null; 
     if (FacesContext.getCurrentInstance()!=null)    
      erpFolder = (AbsErpFolder)FacesUtils.getExternalContext(). 
getRequestMap().get(ErpFolderKey); 
    ............ 
} 

现在我需要使用

WebApplicationContext wsc = WebApplicationContextUtils.getWebApplicationContext(config.getServletContext()); 
IGenericService erpFileService = (IGenericService) wsc.getBean("erpFileService"); 

的问题是期间实例化在FileServlet过滤豆执行我的ServletFile当前的FacesContext为null（动态范围无法工作），那么如何获取当前请求呢？

Answer 1

的ThreadLocal应该做的伎俩 （在我的第一个过滤器定义）

public static ThreadLocal servletRequestHolder = new ThreadLocal(); 
public static HttpServletRequest getCurrentRequest(){ 
    return (HttpServletRequest) servletRequestHolder.get(); 
} 
@Override 
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) 
      throws ServletException, IOException { 
    servletRequestHolder.set(request); 
........... 
}
