Hystrix之@HystrixProperty杂记

@HystrixCommand注解的commandProperties属性是一个@HystrixProperty数组，@HystrixProperty必须指定name和value属性

例如

@HystrixCommand(commandProperties = {@HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "15000")}
)

这个name很长难记吧，其实可以这样

@HystrixCommand(commandProperties = {@HystrixProperty(name = HystrixPropertiesManager.EXECUTION_ISOLATION_THREAD_TIMEOUT_IN_MILLISECONDS, value = "15000")})

@HystrixProperty的name属性值在HystrixPropertiesManager这个类中

public final class HystrixPropertiesManager {private HystrixPropertiesManager() {}/*** Command execution properties.*/public static final String EXECUTION_ISOLATION_STRATEGY = "execution.isolation.strategy";public static final String EXECUTION_ISOLATION_THREAD_TIMEOUT_IN_MILLISECONDS = "execution.isolation.thread.timeoutInMilliseconds";public static final String EXECUTION_TIMEOUT_ENABLED = "execution.timeout.enabled";public static final String EXECUTION_ISOLATION_THREAD_INTERRUPT_ON_TIMEOUT = "execution.isolation.thread.interruptOnTimeout";public static final String EXECUTION_ISOLATION_SEMAPHORE_MAX_CONCURRENT_REQUESTS = "execution.isolation.semaphore.maxConcurrentRequests";/*** Command fallback properties.*/public static final String FALLBACK_ISOLATION_SEMAPHORE_MAX_CONCURRENT_REQUESTS = "fallback.isolation.semaphore.maxConcurrentRequests";public static final String FALLBACK_ENABLED = "fallback.enabled";/*** Command circuit breaker properties.*/public static final String CIRCUIT_BREAKER_ENABLED = "circuitBreaker.enabled";public static final String CIRCUIT_BREAKER_REQUEST_VOLUME_THRESHOLD = "circuitBreaker.requestVolumeThreshold";public static final String CIRCUIT_BREAKER_SLEEP_WINDOW_IN_MILLISECONDS = "circuitBreaker.sleepWindowInMilliseconds";public static final String CIRCUIT_BREAKER_ERROR_THRESHOLD_PERCENTAGE = "circuitBreaker.errorThresholdPercentage";public static final String CIRCUIT_BREAKER_FORCE_OPEN = "circuitBreaker.forceOpen";public static final String CIRCUIT_BREAKER_FORCE_CLOSED = "circuitBreaker.forceClosed";/*** Command metrics properties.*/public static final String METRICS_ROLLING_PERCENTILE_ENABLED = "metrics.rollingPercentile.enabled";public static final String METRICS_ROLLING_PERCENTILE_TIME_IN_MILLISECONDS = "metrics.rollingPercentile.timeInMilliseconds";public static final String METRICS_ROLLING_PERCENTILE_NUM_BUCKETS = "metrics.rollingPercentile.numBuckets";public static final String METRICS_ROLLING_PERCENTILE_BUCKET_SIZE = "metrics.rollingPercentile.bucketSize";public static final String METRICS_HEALTH_SNAPSHOT_INTERVAL_IN_MILLISECONDS = "metrics.healthSnapshot.intervalInMilliseconds";/*** Command CommandRequest Context properties.*/public static final String REQUEST_CACHE_ENABLED = "requestCache.enabled";public static final String REQUEST_LOG_ENABLED = "requestLog.enabled";/*** Thread pool properties.*/public static final String MAX_QUEUE_SIZE = "maxQueueSize";public static final String CORE_SIZE = "coreSize";public static final String KEEP_ALIVE_TIME_MINUTES = "keepAliveTimeMinutes";public static final String QUEUE_SIZE_REJECTION_THRESHOLD = "queueSizeRejectionThreshold";public static final String METRICS_ROLLING_STATS_NUM_BUCKETS = "metrics.rollingStats.numBuckets";public static final String METRICS_ROLLING_STATS_TIME_IN_MILLISECONDS = "metrics.rollingStats.timeInMilliseconds";/*** Collapser properties.*/public static final String MAX_REQUESTS_IN_BATCH = "maxRequestsInBatch";public static final String TIMER_DELAY_IN_MILLISECONDS = "timerDelayInMilliseconds";// 其他方法}
