java Spring工厂-bean工厂-方法 Autowiring

Question

Java-Spring

我在 .xml 中创建了 spring 工厂 bean

<bean id="concurrentHashMapFactory" class="com.abc.HashMapFactory.ConcurrentHashMapFactory"/>
 <bean id="idCorpMap" factory-bean="concurrentHashMapFactory" factory-method="createIdCorpMapInstance"/>

但是我想使用注释将上面的 .xml 语句转换为等效的语句，有什么帮助吗？

大致是这样(我没有测试)..

@Configuration
public class Config {

  @Bean(name = "concurrentHashMapFactory")
  public ConcurrentHashMapFactory createConcurrentHashMapFactory() {
    return new ConcurrentHashMapFactory();
  }

  @Bean(name = "idCorpMap")
  public IdCorpMapType createIdCorpMap(ConcurrentHashMapFactory factory) {
    return factory.createIdCorpMapInstance();
  }
}
