如何记录Spring 5 WebClient调用

如何记录Spring 5 WebClient调用

您可以使用ExchangeFilterFunction轻松完成此 *** 作

在

logRequest

创建

WebClient

using 时，只需添加自定义过滤器

WebClient.Builder

。

这是此类过滤器的示例以及如何将其添加到中

WebClient

。

@Slf4j@Componentpublic class MyClient {    private final WebClient webClient;    // Create WebClient instance using builder.    // If you use spring-boot 2.0, the builder will be autoconfigured for you    // with the "prototype" scope, meaning each injection point will receive    // a newly cloned instance of the builder.    public MyClient(WebClient.Builder webClientBuilder) {        webClient = webClientBuilder // you can also just use WebClient.builder()     .baseUrl("https://httpbin.org")     .filter(logRequest()) // here is the magic     .build();    }    // Just example of sending request    public void send(String path) {        ClientResponse clientResponse = webClient     .get().uri(uriBuilder -> uriBuilder.path(path)  .queryParam("param", "value")  .build())     .exchange()     .block();        log.info("Response: {}", clientResponse.toEntity(String.class).block());    }    // This method returns filter function which will log request data    private static ExchangeFilterFunction logRequest() {        return ExchangeFilterFunction.ofRequestProcessor(clientRequest -> { log.info("Request: {} {}", clientRequest.method(), clientRequest.url()); clientRequest.headers().forEach((name, values) -> values.forEach(value -> log.info("{}={}", name, value))); return Mono.just(clientRequest);        });    }}

然后，只需致电

myClient.send("get");

和日志消息就在那里。

输出示例：

Request: GET https://httpbin.org/get?param=valueheader1=value1header2=value2
