在spring中以编程方式将类的实例绑定到限定符

Question

我有从配置值创建相同类的实例，因此我需要从该配置值注入/自动装配它们。我在guice中这样做：

for (String s : config.getStrings()) {
    bind(Foo.class).annotatedWith(Names.named(s)).toInstance(new Foo(s));
}

有没有办法在Spring中执行此类操作，或者是否有办法使用类似FactoryBean的内容创建给定qualifier的类的实例？

Answer 1

public final class FLEXSyncFactory implements ApplicationContextAware {

    private static AbstractApplicationContext context;

    public void setApplicationContext(ApplicationContext applicationContext)
    throws BeansException {
        context = (AbstractApplicationContext) applicationContext;
    }

注册bean的别名

DefaultListableBeanFactory beanFactory = (DefaultListableBeanFactory) context.getBeanFactory();
Foo fooBean = beanFactory.getBean(Foo.class);
beanFactory.initializeBean(fooBean, "TheAliasForBeanNameYouNeed");
beanFactory.autowireBeanProperties(fooBean, AutowireCapableBeanFactory.AUTOWIRE_BY_TYPE, true);
