spring事务中途提交

    @Autowired
    private DataSourceTransactionManager dataSourceTransactionManager;

  DefaultTransactionDefinition def = new DefaultTransactionDefinition();
        def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRES_NEW); // 事物隔离级别，开启新事务，这样会比较安全些。
        TransactionStatus status = dataSourceTransactionManager.getTransaction(def); // 获得事务状态
        baseSysLoggerService.thread1();
        dataSourceTransactionManager.commit(status);
