spring boot hystrix integration

Question

I have the following method

@HystrixCommand(commandKey="operator",fallbackMethod="getFakeResponse",commandProperties = {
        @HystrixProperty(name = "hystrix.command.operator.execution.isolation.thread.timeoutInMilliseconds", value = "30000")
})
public String getResponse(){

    try {
        Thread.sleep(6000000l);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
    //  e.printStackTrace();
    }


    return "the real thing";
}

when ever I try to run my unit test code to test it, I get the following exception

com.netflix.hystrix.contrib.javanica.exception.HystrixPropertyException: Failed to set Command properties. groupKey: 'HystrixComponentPOC', commandKey: 'operator', threadPoolKey: '' at

com.netflix.hystrix.contrib.javanica.command.GenericSetterBuilder.build(GenericSetterBuilder.java:86) ... 47 more

however, I can run it successfully with the excepted behavior when i remove annotation and add

hystrix.command.operator.execution.isolation.thread.timeoutInMilliseconds=30000

to my properties file

by the way the only configuration I have is @EnableHystrix on my main class and I am using spring boot 1.4.0.RELEASE

any help please?

Answer 1

Are you sure this is the correct command property name? Shouldn't it be

@HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "30000")

instead?

https://github.com/Netflix/Hystrix/wiki/Configuration#execution.isolation.thread.timeoutInMilliseconds

also some snippet from one of their tests that may be helpful https://github.com/Netflix/Hystrix/blob/d838f4d1ba65ce55755ab1c73f74c980f04572bf/hystrix-contrib/hystrix-javanica/src/test/java/com/netflix/hystrix/contrib/javanica/test/common/configuration/command/BasicCommandPropertiesTest.java#L155
