使用Spring boot在侦听器中调用用@RequestScope注释的类

Question

org.springframework.beans.factory.beanCreationException：创建名为“ScopedTarget.MovimentAcaoEntradaradarnotabuilderImpl”的bean时出错：当前线程的范围“request”不活动；如果您打算从单个对象引用这个bean，请考虑为它定义一个限定作用域的代理；嵌套异常是java.lang.IllegalStateException：没有找到线程绑定请求：您是在实际web请求之外引用请求属性，还是在最初接收线程之外处理请求？如果您实际上在web请求中操作，并且仍然接收到此消息，那么您的代码可能在DispatcherServlet/DispatcherPortlet之外运行：在这种情况下，使用RequestContextListener或RequestContextFilter公开当前请求。

@Component
@RequestScope
public class BuilderImplementation implements BuilderInterface {

    @Override
    public void build(){

    }

}

@Component
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
public class MovimentacaoEntradaQueueStorageListener {

    private final @NonNull BuilderInterface builderInterface;

    public MessageStatus listen() {

        builderInterface.build();
    }
}

根据（springs文档），“请求”、“会话”和“全局会话”这三个作用域只有在存在Web感知的应用程序上下文时才有可能：

The scopes that are described in the following paragraphs are only 
available if you are using a web-aware Spring ApplicationContext 
implementation (such as XmlWebApplicationContext). If you try using these 
next scopes with regular Spring IoC containers such as the XmlBeanFactory 
or ClassPathXmlApplicationContext, you will get an IllegalStateException 
complaining about an unknown bean scope.

遵循官方spring文档的指导来解决您的问题。
