Spring-cloud-netflix: Configure @HystrixCommand passing variables.

Created on 22 Jul 2016 · 6Comments · Source: spring-cloud/spring-cloud-netflix

Good morning,

I am using Hyxtrix to implement the Circuit Breaker design pattern. I would like to know how to pass the value using a variable or reading from Config Server

    @HystrixCommand(
        commandProperties = {
            @HystrixProperty(
name="execution.isolation.thread.timeoutInMilliseconds", 
value="500")
    })

Idea 1:

    @Value("${system1.timeout}")
    String system1Timeout;

    @HystrixCommand(
        commandProperties = {
            @HystrixProperty(
name="execution.isolation.thread.timeoutInMilliseconds", 
value="system1Timeout")
    })

This idea doesn't work.

Idea 2:

    @HystrixCommand(
        commandProperties = {
            @HystrixProperty(
name="execution.isolation.thread.timeoutInMilliseconds", 
value="${system1.timeout}")
    })

This idea doesn't work.

Many thanks in advance.

HystrixCommand is third party code. It will never work. You should be able to put those properties in application.yml.

Hi @spencergibb,

If I set the Hyxtrix configuration on application.yml, how to set different values for different Hyxtrix commands?

Hystrix properties cannot be dynamic. It's part of the philosophy of Hystrix. Myself was interested in having a dynamic timeout value depending on the content of my processing, but Hystrix does not permit this feature.

The idea of issue was, how to configure parameters of a HyxtrixCommand outside of the usage.

I found a way:

hystrix:
  command:
    beanMethodInteractingWithSystem1:
      execution:
        timeout:
          enabled: true
        isolation:     
          thread:
            timeoutInMilliseconds: 20000
