I am using Spring WebFlux where I am taking request and using same request to call another service. But I am not sure how to add query parameters. This is my code
@RequestMapping(value= ["/ptta-service/**"])
suspend fun executeService(request: ServerHttpRequest): ServerHttpResponse {
val requestedPath = if (request.path.toString().length > 13) "" else request.path.toString().substring(13)
return WebClient.create(this.dataServiceUrl)
.method(request.method ?: HttpMethod.GET)
.uri(requestedPath)
.header("Accept", "application/json, text/plain, */*")
.body(BodyInserters.fromValue(request.body))
.retrieve()
.awaitBody()
// But how about query parameters??? How to add those
}
Though code is in Kotlin, Java will help as well.

In order to pass single value query parameters, create a path of the base resource URI and then use queryParam() method to append key value pairs.
To use this function you just need to create two NameValueCollections holding your parameters and request headers. Show activity on this post. You can also pass value directly via URL. If you want to call method public static void calling(string name){....}
WebClient provides a higher level API over HTTP client libraries. By default it uses Reactor Netty but that is pluggable with a different ClientHttpConnector.
Logging Request and Response with Body HTTP clients have features to log the bodies of requests and responses. Thus, to achieve the goal, we are going to use a log-enabled HTTP client with our WebClient. We can do this by manually setting WebClient. Builder#clientConnector – let's see with Jetty and Netty HTTP clients.
You can add the query parameters using lambda expression in uri, for more information see WebClient.UriSpec
return WebClient.create(this.dataServiceUrl)
.method(request.method ?: HttpMethod.GET)
.uri(builder -> builder.path(requestedPath).queryParam("q", "12").build())
.header("Accept", "application/json, text/plain, */*")
.body(BodyInserters.fromValue(request.body))
.retrieve()
.awaitBody()
