当前使用版本(必填,否则不予处理)
3.5.1
该问题是如何引起的？(确定最新版也有问题再提!!!)
正常的类继承BaseMapper,使用自带的插入方法，报错 public interface LinkRelMapper extends BaseMapper {
}
重现步骤(如果有就写完整)
Post http://localhost:9308/appReplyCard/saveLinkers [ { "linkId":"123", "businessId":"33333", "linkType":"2" }, { "linkId":"6666", "businessId":"44444", "linkType":"2" } ]
java代码： for (LinkRel linkRel : list) { int insert = linkRelMapper.insert(linkRel); System.out.println("i:"+insert); } 没有打印system就报错
报错信息

求各路大神看下，正常插入报错
