我是一个春天的新手，我试图整合一个简单的春季mvc项目和反应堆：
@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：

有人能给我正确的方法来实现我的目标吗？
谢谢！
答案 0 :(得分：1)
消息说明了一切：你正在尝试在bean中自动装配反应堆，其作用是创建反应堆。它没用，导致你得到的例外。从ReactorConfig类中删除这3个自动装配的字段。
编辑：
再一次，错误信息非常明确：
创建名称为＆＃39; latch＆＃39;的bean时出错在类路径资源[com / gioveviaggi / hsw / ReactorConfig.class]中定义：通过构造函数参数表达的不满意的依赖关系，索引0的类型为[java.lang.Integer]
latch（）方法将Integer作为参数。如果你不告诉它，Spring如何知道哪个值可以作为参数传递？您需要为此整数定义bean或配置的值。或者对值进行硬编码，而不是将其作为参数传递给方法。
