GOURAV MEHTA :
I have a custom gateway filter MYGatewayFilter.java file now i want to use this gateway filter with my route written in application.yml
spring:
cloud:
gateway:
routes:
- id: login2_route
uri: http://127.0.0.1:8083/login
predicates:
- Path: /login/
filters:
How do i define filters for above route
Custom Filter MyGatewayFilter.java
public class MyGatewayFilter implements GatewayFilter {
@Override
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
ServerHttpRequest request;
if(request.getHeaders().get("x-mydata")!=null){
request= exchange.getRequest().mutate().header("my-new-header",request.getHeaders().get("x-mydata").get(0)).build();
}
return chain.filter(exchange.mutate().request(request).build());
}
}
devo :
Instead of implementing GatewayFilter you should implement GatewayFilterFactory
and make it a Component:
@Component
public class MyGatewayFilter implements GatewayFilterFactory {
Then you can refer to it by the bean name in your route.
filters:
- MyGatewayFilter
The documentation on this isn't very good at the moment. I was only able to figure this out by looking at the source code for spring-cloud-gateway on github
