DataSourceUtils.getConnection（jdbcTemplate.getDataSource（））。commit（）;无法运作，即无法提交

Question

我是JDBC模板的新手，并且正在尝试使用准备好的语句通过自动提交模式关闭将数据插入数据库中以实现高性能，但最后我无法提交事务。请提出一些可能解决我问题的正确方法或参考。

预先感谢...

        List<Batch> batchList = new ArrayList<>();
        batchList.add(new Batch("A","B"));
        batchList.add(new Batch("B","B"));

        batchList.add(new Batch("D","B"));
        batchList.add(new Batch("E","B"));
