Zuul Implementing Multiple ZuulFallbackProvider for multiple zuul routes - spring

Question

How can i implement multiple zuulFallbackProvider for multiple zuul routing.
I cant see an answer how to do it using a properties only other than exposing a restcontroller and implement a method with a hystrixcommand.
Can i make each of my service with its own zuulFallBackProvider bean?
application.yml
server:
port: 8080
hystrix:
command:
default:
execution:
isolation:
thread:
timeoutInMilliseconds: 20000
ribbon:
ReadTimeout: 20000
ConnectTimeout: 20000
zuul:
prefix: /api
ignoredServices: '*'
host:
connect-timeout-millis: 20000
socket-timeout-millis: 20000
routes:
kicks-service:
path: /kicks/**
serviceId: kicks-service
stripPrefix: false
sensitiveHeaders:
kicks-inventory:
path: /inventory/**
serviceId: kicks-inventory
stripPrefix: false
sensitiveHeaders:
This is my sample app
#SpringBootApplication
#EnableDiscoveryClient
#EnableZuulProxy
public class GatewayApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayApplication.class, args);
}
#Bean
public Prefilter prefilter(){
return new Prefilter();
}
#Bean
public ZuulFallbackProvider zuulFallbackProvider() {
return new ZuulFallbackProvider() {
#Override
public String getRoute() {
return "kicks-inventory";
}
#Override
public ClientHttpResponse fallbackResponse() {
return new ClientHttpResponse() {
#Override
public HttpStatus getStatusCode() throws IOException {
return HttpStatus.OK;
}
#Override
public int getRawStatusCode() throws IOException {
return 200;
}
#Override
public String getStatusText() throws IOException {
return "OK";
}
#Override
public void close() {
}
#Override
public InputStream getBody() throws IOException {
return new ByteArrayInputStream("fallback".getBytes());
}
#Override
public HttpHeaders getHeaders() {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
return headers;
}
};
}
};
}
}

Answer 1

Each route will need a separate bean. They should return different route for getRoute method.
Please check this- http://tachniki.blogspot.in/2017/02/generic-ZuulFallbackProvider.html. Hope it will make it slightly easier.

Answer 2

You can have a default fallback provider for all routes, otherwise you need a fallback provider per route.
If you would like to provide a default fallback for all routes than
you can create a bean of type FallbackProvider and have the
getRoute method return * or null.
