I integrate Hystrix into the application. This application is ready, and we will test integration using hystrix in the sandbox before we push it to production. My question is, is there a way to enable / disable the hystrix function using some configuration settings?
There is no single setting for this. You will need to set some parameters to disable Hystrix.
For configuration options, see https://github.com/Netflix/Hystrix/wiki/Configuration :
hystrix.command.default.execution.isolation.strategy=SEMAPHORE hystrix.command.default.execution.isolation.semaphore.maxConcurrentRequests=100000 # basically 'unlimited' hystrix.command.default.execution.timeout.enabled=false hystrix.command.default.circuitBreaker.enabled=false hystrix.command.default.fallback.enabled=false
Please double check the version of Hystrix for available parameters.
This is all you need:
# Disable Circuit Breaker (Hystrix) spring: cloud: circuit: breaker: enabled: false hystrix: command: default: circuitBreaker: enabled: false

@Pointcut("@annotation(com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand)") public void hystrixCommandAnnotationPointcut() { } @Around("hystrixCommandAnnotationPointcut()") public Object methodsAnnotatedWithHystrixCommand(final ProceedingJoinPoint joinPoint) throws Throwable { Object result = null; Method method = AopUtils.getMethodFromTarget(joinPoint); if ((System.getProperty(enable.hystrix).equals("true")) { result = joinPoint.proceed(); } else { result = method.invoke(joinPoint.getTarget(), joinPoint.getArgs()); } return result; }
I came across a situation where I wanted to completely disable Hystrix using a single property (we use IBM uDeploy to manage dynamic properties). We use the javanica library built on the basis of Hystrix
@Configuration public class HystrixConfiguration{ @Bean(name = "hystrixCommandAspect") @Conditional(HystrixEnableCondition.class) public HystrixCommandAspect hystrixCommandAspect(){ return new HystrixCommandAspect()} }
@Configuration public class HystrixConfiguration{
@Bean(name = "hystrixCommandAspect") @Conditional(HystrixEnableCondition.class) public HystrixCommandAspect hystrixCommandAspect(){ return new HystrixCommandAspect()} }
2. . public class HystrixEnableCondition implements Condition{ @Override public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata){ return "YES".equalsIgnoreCase( context.getEnvironment().getProperty("circuitBreaker.enabled")) || "YES".equalsIgnoreCase( System.getProperty("circuitBreaker.enabled")); } }
public class HystrixEnableCondition implements Condition{ @Override public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata){ return "YES".equalsIgnoreCase( context.getEnvironment().getProperty("circuitBreaker.enabled")) || "YES".equalsIgnoreCase( System.getProperty("circuitBreaker.enabled")); } }
