我有chunk的Spring批处理作业并设置commit-interval =＆＃34; 3＆＃34;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。
但在我保存的数据库中保存： 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？
