@RequestMapping("apply")
    public ReturnMessage apply(Approval approval){
        this.approvalService.apply(new HashMap<String,Object>(),approval);
        return this.ok();
    }

@Override
    @Transactional
    @WFRun(WFKey = Approval.PROCESS_DEF_KEY, ActionType = ActionType.Start)
    public void apply(Map<String, Object> map, Approval approval) {
        Date now = new Date();
        LoginUser loginUser = this.getLoginUser();
        String id = loginUser.getId().toString();
        String username = loginUser.getUsername();
        approval.setCreatedTime(now);
        approval.setUpdatedTime(now);
        approval.setCreatedUserId(id);
        approval.setCreatedUserName(username);
        approval.setUpdatedUserId(id);
        approval.setUpdatedUserName(username);
        this.getBaseMapper().insert(approval);
    }

$.demo.approval.edit.success = function(){
    //关闭窗口,刷新请假清单
    debugger
    $('#' + $.demo.approval.editWinId).dialog('close');
    $('#' + $.demo.approval.gridId).trigger('reloadGrid');
};
