使用HQL语句时出现StringIndexOutOfBoundsException: String index out of range: -1

[百里非烟]

hql语句时拼接的，按照sql语句改成的，用作sql时没有问题，调用的时候标题所述错误，我的代码如下，希望哪位大神可以帮忙给解决下，谢谢！！
代码：

StringBuilder sb = new StringBuilder("SELECT c FROM CarInfo c,TransportTask t,ConsignmentBill b WHERE t.carNo=c.carCode");
sb.append("AND b.recordId=t.consignmentBill.recordId"+
                  " AND c.load*1000<b.goodsWeight"+
                  " AND t.consignmentBill.recordId =b.recordId"+
                  " AND c.sysInfo.state = 3 AND t.scanFlag IN (1,2)"+
                  " AND c.experimentCode = '"+new MyVisit().getExperimentCode()+
                  "' GROUP BY c.carCode");
		
		
		String hql = sb.toString();
		System.out.println(hql);
		this.setPage(carInfoService.findCarInfoByHql(page, hql));
		return SUCCESS;

不一定是你的查询出错了吧 ，也可能是你在处理结果后的错误吧，你发下你的错误异常LOG看看~
