java - java.lang.UnsatisfiedLinkError：java.library.path 中没有 netty_transport_native_epoll_x86_64

Question

当我尝试在 Spring 应用程序中向 WebClient 发出请求时出现此错误

我已经添加了 netty 依赖项 - https://mvnrepository.com/artifact/io.netty/netty-transport-native-epoll/4.1.53.Final

java.library.path, now trying export to -Dio.netty.native.workdir: /tmp

谁能告诉我可能出了什么问题

编码：

                WebClient webClient = WebClient.builder()
                    .baseUrl("http://url.com") //I cant show the real url
                    .defaultHeader("subject", "Invoice Closing")
                    .build();

                Mono<ClassDTO> classDTOMono = webClient
                    .post()
                    .uri("/uri")
                    .body(BodyInserters.fromValue(classDTO))
                    .header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
                    .retrieve()
                    .bodyToMono(classDTO.class);

                classDTOMono.doOnError(throwable -> System.out.println("message:  " + throwable.getMessage())).block();

当我调用此行时，它会出现此错误： classDTMono.doOnError(throwable -> System.out.println("message: " + throwable.getMessage())).block();
