如何确定我的Spring / Quartz配置正在使用多少个连接?

我使用DataSource,Spring和Quartz不断耗尽数据库连接。如下所示,我的TaskExecutor的maximumPoolSize为30。那么,这是我的安装程序将使用的最大连接数吗?

在corePoolSize = 10的情况下,我的设置是否连续保持10个数据库连接?

我使用的是这样创建的Spring TaskExecutor,并向我的Spring SchedulerFactoryBean注册。

我这样创建一个TaskExecutor:

public TaskExecutor schedulerTaskExecutor() {

        int corePoolSize = 10;
        int maxPoolSize = 30;

        long keepAliveTime = 30000;
        int internalQueueCapacity = 1000;
        boolean allowCoreThreadTimeOut = true;

        ThreadPoolExecutor threadPool = new ThreadPoolExecutor(
                corePoolSize, // core pool size
                maxPoolSize, // max pool size
                keepAliveTime,
                TimeUnit.SECONDS, 
                new LinkedBlockingQueue<Runnable>(internalQueueCapacity)) ;
        threadPool.allowCoreThreadTimeOut(allowCoreThreadTimeOut);

        NamedThreadFactory threadFactory = new NamedThreadFactory("SCHEDULER-");
        threadPool.setThreadFactory(threadFactory);

        return new TaskExecutorAdapter(threadPool);

    }
