unknown command property: circuitBreakerEnabled
at com.netflix.hystrix.contrib.javanica.conf.HystrixPropertiesManager.initializeProperties

今天在学习尚硅谷周阳老师的spring cloud 服务熔断

访问http://127.0.0.1:8001/payment/hystrix/circuit_breaker/1 时报错报错信息如下

看了service的熔断配置

 //===服务熔断===
    @HystrixCommand(fallbackMethod = "circuitBreaker_fallback",commandProperties = {
            @HystrixProperty(name = "circuitBreakerEnabled",value = "true"),//是否开启熔断器
            @HystrixProperty(name = "circuitBreakerRequestVolumeThreshold",value = "10"),//请求次数
            @HystrixProperty(name = "circuitBreakerSleepWindowInMilliseconds",value = "5"),//时间窗口期
            @HystrixProperty(name = "circuitBreakerErrorThresholdPercentage",value = "60"),//失败率达到多少后跳闸

    })
    public String paymentCircuitBreker(Integer id){
        if(id<0){
            throw new RuntimeException("***id 不能小于0 ***");
        }
        String serialNumber = IdUtil.simpleUUID();
        return "线程："+Thread.currentThread().getName()+"调用成功,流水号"+serialNumber;

    }

是因为哦这里的@HystrixProperty的name都写错了
应该是

@HystrixCommand(fallbackMethod = "circuitBreaker_fallback",commandProperties = {
            @HystrixProperty(name = "circuitBreaker.enabled",value = "true"),//是否开启熔断器
            @HystrixProperty(name = "circuitBreaker.requestVolumeThreshold",value = "10"),//请求次数
            @HystrixProperty(name = "circuitBreaker.sleepWindowInMilliseconds",value = "5"),//时间窗口期
            @HystrixProperty(name = "circuitBreaker.errorThresholdPercentage",value = "60"),//失败率达到多少后跳闸

    })

错误解决！！

这里也报同样的错了后来发现是因为 name = “” 引号中的内容前面有一个空格，把空格去掉就好了
