storm初始化Bolt实例,spring bean绑定失败原因排查

 

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．
