Spring WebClient get请求返回“连接拒绝：localhost/”

Question

当我试图用WebClient发送GET请求时，我响应错误io.netty.channel.AbstractChannel$annotatedConnectException：Connection Delection:localhost/

*WebClient初始化*

//hostname = "localhost/127.0.0.1:8081"
//contextPath = "user-service"

    @Bean
    public WebClient userWebclient(@Value("${service.user.hostname}") final String hostname,
                                  @Value("${service.user.contextPath}") final String contextPath) {
        return WebClient
                .builder()
                .baseUrl(hostname + contextPath)
                .build();
    }

    private final WebClient userWebclient;

    @GetMapping(value = "/user/{id}", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
    public Mono<String> getUserById(@NotNull @PathVariable String userId) {
        userWebclient.

        return userWebclient.get()
               .uri("/UserMock/user/" + userId)
               .header("Accept", "application/json")
               .header("Authorization", "Bearer =........")
               .exchange()
               .flatMap(response -> response.bodyToMono(String.class));
    }

检查您的地址是否正确，这个错误可能是因为您的端口号不是像8081一样正确，但应该是8080
