struts1.2+hibernate+spring整合的异常处理相关问题

    最近遇到了严重的问题，搞了几天无法保存异常信息到数据库。
    在dao、service等注入而使用的环境下，如何才能在异常中处理类中调用这些业务方法来存取异常信息。
    对struts2.0+hibernate+spring整合比较熟，但是对struts1.2+hibernate+spring真的是无奈能解决，郁闷，唉，到了几天都。public class ExceptionHandler extends org.apache.struts.action.ExceptionHandler{
/**
 * Commons logging instance.

protected Logger log = Logger.getLogger(ExceptionHandler.class); public final static String EXCEPTION_STACKTRACE = "errStackTrace";

protected AdminFacadeManager adminFacadeManager=new AdminFacadeManagerImpl(); //方法1new一个实例，
         // 还是用不了
         /*public void setAdminFacadeManager(AdminFacadeManager adminFacadeManager) {
System.out.println("@@@@@@@@@@@@@@@@@@@@@adminFacadeManager注入ExceptionHandler成功！！！！！");
this.adminFacadeManager = adminFacadeManager; //方法2注入不成功 }*/ /*public ExceptionManager getExceptionManager() {

maskExceptionModel=new MaskExceptionModel("java.lang.Exception", message,

就是这里保存时，显示dao.save(object)空指针异常
if (!response.isCommitted()) {
return forward;
}
return null;
} protected void storeException(HttpServletRequest request, String property,
ActionMessage error, ActionForward forward, String scope) {
ActionMessages errors = new ActionMessages(); errors.add(property, error); if ("request".equals(scope)) {
request.setAttribute(Globals.ERROR_KEY, errors);
} else {
request.getSession().setAttribute(Globals.ERROR_KEY, errors);
}
} protected String stackTrace2String(StackTraceElement[] stackTrace) {
StringBuffer stackString = new StringBuffer(0);
for (int i = 0; i < stackTrace.length; i++) {
stackString.append(stackTrace[i].toString()).append("\r\n");
}
return stackString.toString();
}}希望高手快来帮忙。郁闷啊。我感之不尽
