之前我把super.delete(info);这句话放到了ZbzyZbInfo info = super.fetch(ZbzyZbInfo.class, id);这句话后面，然后ZbzyZbRentOut rent = super.fetch(ZbzyZbRentOut.class, info.getInfoId());这句话报空指针异常但是info这条数据已经删除了

是不是有更高层的事务模板, 把这一层的事务忽略了

```
public boolean deleteInfo(String ids){
boolean result = false;
try{
Trans.exec((Atom) () -> {
if(StringTool.isNotNull(ids)) {
String[] idss = ids.split(",");
for (String id : idss){
if (!StringUtil.isEmpty(id)){
ZbzyZbInfo info = super.fetch(ZbzyZbInfo.class, id);
ZbzyZbRentOut rent = super.fetch(ZbzyZbRentOut.class, info.getInfoId());
ZbzyZbVehicle vehicle = super.fetch(ZbzyZbVehicle.class, rent.getToolId());
super.delete(info);
super.delete(rent);
super.delete(vehicle);
}
}

            }
        });
        result = true;
    } catch (Exception ex){
        log.error("AdminZbRentOutVehicleInfoService:insertInfo", ex);
    }
    return result;
}

大佬 这个是完整的方法

异常信息贴来看看

是不是有aop 事务

来自炫酷的 NutzCN

$aop : {
		type : 'org.nutz.ioc.aop.config.impl.JsonAopConfigration',
		fields : {
			itemList : [ 
			             [ 'com.zbzy.services\\..*', '(insert|update|delete|tx).*', 'ioc:txREPEATABLE_READ' ]
			             [ 'com.zbzy.web.backend.module\\..*', '.*', 'ioc:common' ]
						]
		}
	}

因为在aop事务作用域内，所以不回滚

你可以看看NutTxDao，开启独立事务
