@Configuration
public class SessionCheckInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
        HttpSession httpSession = request.getSession();
        if(httpSession.getAttribute(Constant.SESSION_DEPT_SPACE_CODE)==null) {
            httpSession.setAttribute(Constant.SESSION_DEPT_SPACE_RELATION_DEPT_CODE, Constant.NO_RELATION_DEPT_CODE);
            httpSession.setAttribute(Constant.SESSION_DEPT_SPACE_CODE, Constant.NO_DEPT_SPACE_CODE);
        }
//        if(httpSession.getAttribute(Constant.SESSION_DGDPS_ROLE_TYPE)==null) {
//            httpSession.setAttribute(Constant.SESSION_DGDPS_ROLE_TYPE, DgdpsportalConstant.DGDPS_ROLE_TYPE_OTHER);
//        }
        return true;
    }
}
