Example 1 with FallbackMethod

use of com.netflix.hystrix.contrib.javanica.utils.FallbackMethod in project Hystrix by Netflix.

the class HystrixCommandAspect method setFallbackMethod.

private static MetaHolder.Builder setFallbackMethod(MetaHolder.Builder builder, Class<?> declaringClass, Method commandMethod) {
    FallbackMethod fallbackMethod = MethodProvider.getInstance().getFallbackMethod(declaringClass, commandMethod);
    if (fallbackMethod.isPresent()) {
        fallbackMethod.validateReturnType(commandMethod);
        builder.fallbackMethod(fallbackMethod.getMethod()).fallbackExecutionType(ExecutionType.getExecutionType(fallbackMethod.getMethod().getReturnType()));
    }
    return builder;
}

Example 2 with FallbackMethod

use of com.netflix.hystrix.contrib.javanica.utils.FallbackMethod in project Hystrix by Netflix.

the class HystrixCommandBuilderFactory method createFallbackAction.
