在Spring-Boot应用程序中使用application.yaml配置hystrix命令属性

Question

hystrix:
   command.StoreSubmission.execution.isolation.thread.timeoutInMilliseconds: 30000
   command.StoreSubmission.circuitBreaker.requestVolumeThreshold: 4
   command.StoreSubmission.circuitBreaker.sleepWindowInMilliseconds: 60000
   command.StoreSubmission.metrics.rollingStats.timeInMilliseconds: 180000
   collapser.StoreSubmission.maxRequestsInBatch: 1
   collapser.StoreSubmission.requestCache.enabled: FALSE
   threadpool.StoreSubmission.coreSize: 30
   threadpool.StoreSubmission.metrics.rollingStats.timeInMilliseconds: 180000

主要问题是，我使用groupKey值而不是commandKey值来定义属性。这些配置属性的wiki页面--https://github.com/netflix/hystrix/wiki/configuration#intro说明-

hystrix.command.HystrixCommandKey.execution.isolation.thread.timeoutInMilliseconds

用为CommandKey设置的值替换属性的HystrixCommandKey部分。

hystrix.threadpool.HystrixThreadPoolKey.coreSize

用为ThreadPoolKey设置的值替换属性的HystrixThreadPoolKey部分。

@HystrixCommand(groupKey = "StoreSubmission", commandKey = "StoreSubmission", threadPoolKey = "StoreSubmission")
public String storeSubmission(ReturnType returnType, InputStream is, String id) {
}

@HystrixCommand(groupKey = "StoreSubmission", commandKey = "StoreSubmission", threadPoolKey = "StoreSubmission", commandProperties = {
        @HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "30000"),
        @HystrixProperty(name = "circuitBreaker.requestVolumeThreshold", value = "4"),
        @HystrixProperty(name = "circuitBreaker.sleepWindowInMilliseconds", value = "60000"),
        @HystrixProperty(name = "metrics.rollingStats.timeInMilliseconds", value = "180000") }, threadPoolProperties = {
        @HystrixProperty(name = "coreSize", value = "30"),
        @HystrixProperty(name = "metrics.rollingStats.timeInMilliseconds", value = "180000") })
public String storeSubmission(ReturnType returnType, InputStream is, String id) {
}
