我正在尝试使用 Spring WebFlux WebClient获取值（字符串） （使用 SpringBoot 版本 2.4.5）

@GetMapping("/test")\npublic Mono<String> getData(){\n    WebClient webClient = WebClient.create("http://localhost:9999");\n    Mono<String> stringMono = webClient.get()\n            .uri("/some/thing")\n            .retrieve()\n            .bodyToMono(String.class);\n    stringMono.subscribe( System.out::println);\n    System.out.println("Value : " + stringMono.block()); // this doesn\'t work,  expecting to return ResponseBody as "Hello World" ,\n    return stringMono;\n}\n

但低于错误
