Original code

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

Possible reasons

1. The namespace in the mapper.xml is different from the actual class#

Checked and consistent

2. The function name in the mapper interface is different from the id in the mapper.xml tag#

selectBatchIds is the default method of com.baomidou.mybatisplus.core.mapper.BaseMapper<xx 业务>

Fixed code

@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)
	);
}
