跑了一年的代码报错。。。

原本的代码

@DS("xxxx")
public List<xx业务> getxx业务s(List<Long> uid) {
	return xx业务Mapper.selectBatchIds(uid);
}

可能原因

1.mapper.xml 里面的 namespace与实际类不一样

排查,一致

2.mapper接口的函数名称和mapper.xml里面的标签id不一致

selectBatchIds 是com.baomidou.mybatisplus.core.mapper.BaseMapper<xx业务> 的默认方法

修复的代码

@DS("xxxx")
public List<xx业务> getxx业务s(List<Long> uid) {
		return  xx业务Mapper.selectList(new LambdaQueryWrapper<xx业务>()
			.in(xx业务::getUid, uid)
	);
}
