public static final String METRICS_AGGREGATE_PERIOD_MILLISECONDS = "metrics.storm.aggregate.period.milliseconds"; @Value("${" + METRICS_AGGREGATE_PERIOD_MILLISECONDS + "}") private long metricsAggregateIntervalMilliSeconds;
上面这样书写，Bolt实例化后metricsAggregateIntervalMilliSeconds的值为null
public static final String METRICS_AGGREGATE_PERIOD_MILLISECONDS = "metrics.storm.aggregate.period.milliseconds"; @Value("${" + METRICS_AGGREGATE_PERIOD_MILLISECONDS + "}") private transient long metricsAggregateIntervalMilliSeconds;
上面这样写，Bolt实例化后metricsAggregateIntervalMilliSeconds的值为0
public static final String METRICS_AGGREGATE_PERIOD_MILLISECONDS = "metrics.storm.aggregate.period.milliseconds"; @Value("${" + METRICS_AGGREGATE_PERIOD_MILLISECONDS + "}") private long metricsAggregateIntervalMilliSeconds;
这样写就正常了．
原因未知，先记上，稍后排查．
