看报错日志，BaseOrderToOrderVOMapperImpl 中调用了 ConverterMapperAdapeter 的方法进行转换。 ConverterMapperAdapeter 是通过 Spring 容器注入的，报空指针那就是没有注入进来。这种应该不存在环境不一致会出现不同的效果吧。建议本地复现排查下，在 BaseOrderToOrderVOMapperImpl 中打断点，执行转换逻辑，看下注入失败的原因。

也有可能 ConverterMapperAdapeter 这个类所在的包，SpringBoot 扫描不到。

Apr 11 '24 02:04 linpeilie

正在尝试加入scan

Apr 11 '24 02:04 LoptrX

mapstruct-plus-springboot-starter 中是有加入默认的包扫描的，有修改过么

Apr 11 '24 02:04 linpeilie

没有

mapstruct-plus-springboot-starter 中是有加入默认的包扫描的，有修改过么

没有的，很神奇，为啥这个order的mapperImpl有个单独的ConverterMapperAdapter

Apr 11 '24 03:04 LoptrX

有这个没啥关系呀，为啥会扫描不到呢

抱歉，最近太忙，忘记回复了，情况紧急使用了beanUtil去处理了

发现问题了，原因是我手动创建了一个converter实例，但是不知道为何这个mapper会出现adaptor为空，删除手动创建的converter就正常了

类似的问题找了好久，也是new Converter导致的了"cannot find converter from xxx to xxx"
