当前使用版本(必填,否则不予处理)
3.5.2
该问题是如何引起的？(确定最新版也有问题再提!!!)
批量插入的时候报空指针
重现步骤(如果有就写完整)
我的sql
==> Preparing: INSERT INTO TDTEP01 ( REC_CREATOR, REC_CREATE_TIME, PROJECT_CODE, CODE_CLASS, CODE_CLASS_DESC ) VALUES ( ?, ?, ?, ?, ? )
==> Parameters: admin(String), 20221209152221(String), TEST_FORM_DEV(String), EPTEST01(String), 测试(String)
我的实体类 ID @TableId(value = "ID", type = IdType.AUTO) private Integer id;
