1.@HystrixCommand方式呢，很污染代码，将Hystrix的配置装移到yaml当中
loginFail与登录的降级熔断一致，一一对应就好
hystrix:
command:
# 有的属性是默认值，写不写都行
default:
fallback:
enabled: true
circuitBreaker:
enabled: true
# 超过50%错误，那么开启熔断
errorThresholdPercentage: 50
# 5个request之后才进行统计
requestVolumeThreshold: 5
# 10秒之后进入半开状态
sleepWindowInMilliseconds: 10000
# forceClosed, forceOpen 强制关闭/开启熔断开关
execution:
timeout:
enabled: true
# 可以指定隔离方式是线程池还是信号量
isolation:
thread:
interruptOnTimeout: true
interruptOnFutureCancel: true
timeoutInMilliseconds: 10000
metrics:
rollingStats:
# 时间窗口统计
timeInMilliseconds: 20000
# numBuckets: 10
# rollingPercentile:
# # 时间窗口统计
# timeInMilliseconds: 20000
# # numBuckets: 10
# bucketSize: 300
# 照这个方法，覆盖其他的属性
loginFail:
execution:
isolation:
thread:
timeoutInMilliseconds: 3000
