我是一个春天的新手，我正在尝试在一个简单的 spring mvc 项目中集成一个反应器：

@Controller
public class HomeController {

    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
    @Autowired
    Reactor reactor;

    @Autowired
    private Receiver receiver;

    @Autowired
    private Publisher publisher;

    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Locale locale, Model model) {
        logger.info("Welcome home! The client locale is {}.", locale);

        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);

        String formattedDate = dateFormat.format(date);

        reactor.on($("jokes"), receiver);
        try {
            publisher.publishJokes();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }


        model.addAttribute("serverTime", formattedDate );

        return "home";
    }

}

配置类

@Configuration
public class ReactorConfig {

    @Bean
    Environment env() {
        return new Environment();
    }

    @Bean
    Reactor createReactor(Environment env) {
        return Reactors.reactor()
                .env(env)
                .dispatcher(Environment.THREAD_POOL)
                .get();
    }


    @Bean
    public CountDownLatch latch(Integer numberOfJokes) {
        return new CountDownLatch(numberOfJokes);
    }   


}

当我尝试在 tomcat 上部署时，它总是给我很多例外，例如：

该消息说明了一切：您正在尝试在角色是创建反应器的 bean 中自动装配反应器。它没用，并导致您得到异常。从 ReactorConfig 类中删除这 3 个自动装配字段。

编辑：

再次，错误信息非常清楚：

创建在类路径资源 [com/gioveviaggi/hsw/ReactorConfig.class] 中定义的名称为“latch”的 bean 时出错：通过构造函数参数表示的不满足依赖关系，索引为 0 类型 [java.lang.Integer]

latch() 方法接受一个 Integer 作为参数。如果您不告诉它，Spring 怎么会知道将哪个值作为参数传递？您需要为此整数定义一个 bean 或配置值。或者对值进行硬编码，而不是将其作为参数传递给方法。
