在 Spring Web 客户端中发送请求参数

Question

我想在 Spring WebClient 请求链接中发送链接请求参数。例如：

https://www.test.com/notification?con=41280440000097&sec=1232

我试过这段代码：

WebClient client;

Map<String, String> map = new HashMap<>();

public Mono<Response> execute(Transaction transaction) {

    map.put("some_key", "some_value");

    Mono<PaymentTransaction> transactionMono = Mono.just(transaction);

    return client.post().uri("/notification", token)
                .accept(MediaType.APPLICATION_XML)
                .contentType(MediaType.APPLICATION_XML)
                .body(transactionMono, Transaction.class)
                .attributes(Consumer<map>)
                .retrieve()
                .bodyToMono(Response.class);
}

但是当我尝试设置地图时，我在令牌 ">" 上出现语法错误，此之后的表达式预期

不将值硬编码到地址中​​的正确方法是什么？

这行得通吗？

public Mono<PaymentResponse> execute(PaymentTransaction transaction, WebClient client) {
        long conn = 1L;
        int sec = 1232;

        Mono<PaymentTransaction> transactionMono = Mono.just(transaction);
        return client.post()
                .uri(uriBuilder -> uriBuilder.scheme("https").host("www.test.com")
                        .path("notification")
                        .queryParam("con", conn)
                        .queryParam("sec", sec)
                        .build())
                .accept(MediaType.APPLICATION_XML)
                .contentType(MediaType.APPLICATION_XML)
                .body(transactionMono, PaymentTransaction.class)
                .retrieve()
                .bodyToMono(PaymentResponse.class);
    }
