DB2数据库上saveBatch的NPE问题 #5928

Open GeorgeAnson opened 9 months ago

GeorgeAnson commented 9 months ago

当前使用版本(必填,否则不予处理)

3.5.5

该问题是如何引起的？(确定最新版也有问题再提!!!)

mp版本从3.4.1跨版本升级到了3.5.5，saveBatch方法批量保存报错。 查看错误原因应该是主键问题造成的。

重现步骤(如果有就写完整)

1.新建一个日志对象，主键为自增，数据库采用DB2数据库，其他数据库未测试 image 2.写一个批量保存的接口 image 3.提交测试方法即报错。

你好，问题解决了吗 @GeorgeAnson

尚未解决，调试跟踪进入到源码中，发现此处报错 84192991eac0f5460201e61e513a706

在他的上一层，batchResultList中获取到的对象中，这个generatedKey对象是空 ，是否是跟mybaitsplus或者mybtis的配置有关，尚未抽出时间去看 1880fe952a6825777a20134f07189da

无环境调试，更新到3.5.6试试看看

后面我尝试更新到了最新的3.5.6版本，测试结果也是一样的

配置dbconfig.insertIgnoreAutoIncrementColumn=true

GeorgeAnson commented 6 months ago

配置dbconfig.insertIgnoreAutoIncrementColumn=true

3.5.6版本添加配置 mybatis-plus: global-config: db-config: insert-ignore-auto-increment-column: true

执行批量出现了如下报错，另一个NPE异常 image

配置dbconfig.insertIgnoreAutoIncrementColumn=true

然后我尝试将keyProperties的值清空，设置为null，不走下面逻辑，直接走上一步的return逻辑，发现可以正常插入数据，无报错。如下图： image

检查下驱动是否有升级，然后方便就提供复现工程和环境.
