java - TimerTask Scheduler 在静态引用其他类对象后不起作用

Question

我有一个参考其他类的 TimeTask 类。现在，当我创建对另一个类的静态引用时；它只执行该类的静态块并且定时器任务类的主要方法没有执行；

我可能会在 IbftUtil.java 类中做某种引用错误，我试图通过引入该静态块来使事情成为单例。

请帮忙。

ibftUtil.java

static {

        try {

            /******************** Read Properties file.. ***************/ 

            LOGGER.println( LOG + " Loading properties file.." );

            InputStream inputStream = new FileInputStream( new File( FMS_PROPERTY_FILE ) );

            fmsProperties = new Properties();

            fmsProperties.load( inputStream );

            LOGGER.println( LOG + " Properties Loaded Successfully" );

            inputStream.close();

            LOGGER.println( LOG + " Reading properties values.. " );

            // Timer attributes..
            delayTime = Long.parseLong( fmsProperties.getProperty ( IBFT_DELAY_TIME ) );
            executionTime = Long.parseLong( fmsProperties.getProperty ( IBFT_EXECUTION_TIME ) );

            LOGGER.println( LOG + " IBFT DELAY & EXECUTION TIME = " + getDelayTime() + "," + getExecutionTime());

            // Key-store and certificate ..
            ibftReceiverCertificate = fmsProperties.getProperty( IBFT_RECEIVER_CERTIFICATE );
            ibftSenderKeyStore = fmsProperties.getProperty( IBFT_SENDER_KEY_STORE );
            ibftKeyStoreAlias = fmsProperties.getProperty( IBFT_KEY_STORE_ALIAS );

            // Key store credentials..
            ibftKeyStoreKey = fmsProperties.getProperty( IBFT_KEY_STORE_KEY );
            ibftKeyStorePath = fmsProperties.getProperty( IBFT_KEY_STORE_PASS );

            // Copy file path..
            ibftPaymentFiles = fmsProperties.getProperty( IBFT_PAYMENT_FILES );

            LOGGER.println( LOG + " Properties values read successfully!.. " );

        }
