Spring MVC中添加豆類和自動裝配

Question

我是一個新手春天，我想在一個簡單的Spring MVC項目集成了反應器：

@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"; 
    } 

} 

配置類

@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); 
    } 


} 

當我試圖在tomcat上部署它總是給我很多例外，如：

Answer 1

的消息說，這一切：你想在它的作用是創建反應器中的豆自動裝配反應器。這是無用的，並導致你得到的例外。從您的ReactorConfig類中刪除這3個自動佈線字段。

編輯：

再次，該錯誤消息是很清楚的：

錯誤創建與名稱豆 '鎖存' 類路徑資源定義[COM/gioveviaggi/HSW/ReactorConfig.class] ：通過類型爲[java.lang.Integer]的索引0的構造方法參數表示的不完全依賴關係

latch（）方法將整數作爲參數。如果你不告訴它，Spring如何知道哪個值作爲參數傳遞？您需要爲此整數定義一個bean或配置的值。或者硬編碼該值並且不將其作爲參數傳遞給該方法。
