我有chunk的Spring批处理作业并设置commit-interval =“3”并声明了可跳过的异常 . 我想在DB中保存3项:item_1 item_2 item_3

说,我想将这些项目保存在数据库中,但第二项无效并发生异常 . 在这种情况下应该回滚并且Spring Batch应该单独重新运行有问题块的每个项目,每个项目一次提交/事务 . 所以在数据库中应该保存item_1和item_3 .

但在我的情况下保存数据库:item_1 item_1 item_3因此item_1是重复的 . 看起来 item_1 在发生异常之前提交,或者在发生异常后没有回滚 .

我整天都在这个案子上,但仍然不知道出了什么问题 .

下面,Spring批处理作业配置 . 你知道什么是错的吗?
