资源甚至在计划任务完成执行之前就被销毁

Question

我正在尝试使用ThreadPoolTaskScheduler安排一些任务执行，但是我注意到，即使在任务完成执行之前，Spring应用程序上下文也开始破坏所有资源。

    private JdbcTemplate jdbcTemplate;
    private TransactionTemplate transactionTemplate;
    private ThreadPoolTaskScheduler threadPoolTaskScheduler;

    public TestClass(final JdbcTemplate jdbcTemplate
                     final TransactionTemplate transactionTemplate,
                     final ThreadPoolTaskScheduler threadPoolTaskScheduler) {
    .... }

    public void start() {
            threadPoolTaskScheduler.execute(() -> {
                try {
                    // Try to claim the job. If the job is successfully claimed, then run the task.
                    claim(unitOfWork.getName()).ifPresent(this::runTask);
                } finally {
                    onComplete.accept(this);                    
                }
            });

private Job claim(final String code) {
....
... findJobByCode(code);
... updateJob(code);
}

private Job findJobByCode(final String code) {
....
transactionTemplate.execute((status) -> {
                        final String query = "select * from .... where...";

                        return jdbcTemplate.queryForObject(query,
                                                           (resultSet, rowNum) -> mapResultSetToJob(resultSet),
                                                           code);
                    }));

}

private int updateJob(final String code) {
....
transactionTemplate.execute((status) -> {
                        final String query = "update .... where...";

                        return jdbcTemplate.update(query, ...);
                    }));
....
}

以下是异常代码段，在该代码段中，我们可以看到任务调度程序正在执行，并且在这之间资源开始关闭。

需要一种方法来告诉Spring不要在计划执行Taks时关闭数据源和其他资源。
