@HystrixCommand的使用对于应用开发来说非常方便，但也有个限制就是像动态修改注解的属性就很麻烦。
因为被该注解标注的方法在执行前是被com.netflix.hystrix.contrib.javanica.aop.aspectj.HystrixCommandAspect实时地读取注解元数据的，同时Hystrix内部只提供了Archaius动态配置，但也是有不小的使用限制。
另类解决方式：
`@Aspect
@Component
public class MyHystrixCommandAspect {
public static BooleantimeoutInMilliseconds = Boolean.FALSE;
@Pointcut("@annotation(com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand)")
public void hystrixCommandAnnotationPointcut() {
}
@Around("hystrixCommandAnnotationPointcut()")
public ObjectmethodsAnnotatedWithHystrixCommand(final ProceedingJoinPoint joinPoint)throws Throwable {
if(timeoutInMilliseconds){
System.out.print("%%%%%%%%%%%%%%%%%%%%%");
Method method =getMethodFromTarget(joinPoint);
HystrixCommand hystrixCommand = method.getAnnotation(HystrixCommand.class);
HystrixProperty[] hystrixProperties = hystrixCommand.commandProperties();
for (HystrixProperty hystrixProperty : hystrixProperties){
if("execution.isolation.thread.timeoutInMilliseconds".equals(hystrixProperty.name())){
InvocationHandler h = Proxy.getInvocationHandler(hystrixProperty);
Field hField = h.getClass().getDeclaredField("memberValues");
hField.setAccessible(true);
Map memberValues = (Map) hField.get(h);
memberValues.put("value", "6000");
}
}
}
Object obj = joinPoint.proceed();
return obj;
}
}`
