有时Hibernate会在其方法中抛出IllegalArgumentException，我不知道为什么，也不知道如何重现。Hibernate AbstractBatchImpl sql必须为非null
我使用Spring Batch的尝试处理文件，并在ItemWriter我节省记录到数据库（创建/更新），就像这样：
public class ProductWriter implements ItemWriter<ProductRecord> {
@Autowired private ProductRepository repository;
@Override
@Transactional
public void write(List<? extends ProductRecord> records) throws Exception {
// ... use repository to create or find/update ...
}
}
于是有时我得到一个IllegalArgumentException “SQL必须为非空”从休眠：
org.springframework.dao.InvalidDataAccessApiUsageException: sql must be non-null.; nested exception is java.lang.IllegalArgumentException: sql must be non-null.

我有什么调查不知道，这事我做错了或者是一个Hibernate的错误？
