I am trying to send an object to the endpoint but I do not understand why I can't do it with .get(), why .post() has to be used? What if the endpoint method takes an object and does something with it and returns an object? I may want to send an object to the endpoint which takes the object as an argument. Is there a way to do it? How to pass a customer object to getCustomer() endpoint.

WebClient.create("http://localhost:8080")
            .get()//why this can not be used? why post has to be used?
            .uri("client/getCustomer")
            .contentType(MediaType.APPLICATION_JSON)
            .bodyValue(customer)//with .get() body cannot be passed.
            .retrieve()
            .bodyToMono(Customer.class);


        @GET
        @Path("/getCustomer")
        @Produces(MediaType.APPLICATION_JSON)
        @Consumes(MediaType.APPLICATION_JSON)
        public Customer getCustomer(Customer customer) {
            //do something
            return customer;
        }

In GET methods, the data is sent in the URL. just like: http://www.test.com/users/1

In POST methods, The data is stored in the request body of the HTTP request.

Therefore we should not expect .get() method to have .bodyValue().

Now if you wanna send data using GET method, you should send them in the URL, like below snippet

   WebClient.create("http://localhost:8080")
            .get()
            .uri("client/getCustomer/{customerName}" , "testName")
            .retrieve()
            .bodyToMono(Customer.class);
