Let asy that there are several org.springframework.web.reactive.function.client.WebClient classes in the application which creatred like that:

@Bean

@Qualifier("one")

public WebClient one() {

    return WebClient.builder().baseUrl("someUrl").build();

}

@Bean

@Qualifier("two")

public WebClient two() {

    return WebClient.builder().baseUrl("someUrl").build();

}

//etc.

It is needed to add filters for all create WebClients. Some thing like that:

public WebClient intercepter(WebClient webClient) {

    return webClient.mutate().filter(setupFilter());

}

Can this be possible with spring 5?

I assume you don't have permissions to modify the code of beans provided?

In that case you can implement a BeanPostProcessor - detect WebClient implementations (or methods by return type) and return updated value in each method.

Alternatively you can replace the real implementation of WebClient with the decorator in your post-processor.

Here is the example of how to implement a processor. In this case Locking operations are being injected into original methods.

Don't forget to include your post processor to the context
