如何在Spring中实例化lite模式bean？

Question

在Spring文档中说@Bean annotation can be applied to methods even in components and POJOs。

但是如何实例化这些bean？

以下代码抛出NoSuchBeanDefinitionException。它还表明，当调用方法时，bean会被构造几次（这与关于检测的单词一致，但与关于范围的单词不一致）。

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

public class LiteModeBeans {

   public static class Database {
   }

   public static class MyClass {

      {
         System.out.println("Constructed");
      }

      private Database database;

      public Database getDatabase() {
         return database;
      }

      @Autowired
      public void setDatabase(Database database) {
         this.database = database;
         System.out.println("Database set");
      }
   }


   public static class LiteContainingBean {

      @Bean
      MyClass myClass() {
         return new MyClass();
      }

      public MyClass getMyClass() {
         return myClass();
      }
   }


   @Configuration
   public static class Config {

      @Bean
      Database database() {
         return new Database();
      }

      @Bean
      LiteContainingBean liteContainingBean() {
         return new LiteContainingBean();
      }


   }


   public static void main(String[] args) {

      AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(Config.class);

      MyClass myClass;

      LiteContainingBean liteContainingBean = ctx.getBean(LiteContainingBean.class);
      myClass = liteContainingBean.myClass();
      myClass = liteContainingBean.myClass();

      myClass = ctx.getBean(MyClass.class); // No qualifying bean of type [com.inthemoon.snippets.springframework.LiteModeBeans$MyClass] is defined
      System.out.println("MyClass: " + myClass.toString());



   }

}

那么，如何通过Spring创建和处理MyClass的bean？

以下工作，谢谢@MDeinum：

public class LiteModeBeans {

   public static class Database {
   }

   public static class MyClass {

      {
         System.out.println("Constructed");
      }

      private Database database;

      public Database getDatabase() {
         return database;
      }

      @Autowired
      public void setDatabase(Database database) {
         this.database = database;
         System.out.println("Database set");
      }
   }


   @Component
   public static class LiteContainingBean {

      @Bean
      MyClass myClass() {
         return new MyClass();
      }

   }


   @Configuration
   public static class Config {

      @Bean
      Database database() {
         return new Database();
      }


   }


   public static void main(String[] args) {

      AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(Config.class, LiteContainingBean.class);

      MyClass myClass;

      myClass = ctx.getBean(MyClass.class); // No qualifying bean of type [com.inthemoon.snippets.springframework.LiteModeBeans$MyClass1] is defined
      System.out.println("MyClass1: " + myClass.toString());



   }
