spring 启动 hystrix 集成

Question

我有以下方法

@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";
}

当我尝试运行我的单元测试代码来测试它时，我得到以下异常

但是，当我删除注释并添加

时，我可以运行使用异常行为成功

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

到我的属性文件

顺便说一下，我唯一的配置是我的主 class 上的 @EnableHystrix，我正在使用 spring boot 1.4.0.RELEASE

有什么帮助吗？

Answer 1

您确定这是正确的命令属性名称吗？不应该是

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

代替？

还有一些可能有用的测试片段 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
