如何在Spring中按类型创建bean? [英] How to create a bean by type in Spring?

问题描述

在我的ApplicationContext中，我创建了几个具有相同样式的Bean.因此，我有很多重复的代码为每个bean编写一个FactoryBean.这些bean具有共同点，实现了所有一个特殊接口.

In my ApplicationContext I have several Beans being created the same style. So I have a lot of dublicated code writing a FactoryBean for each of this beans. Those beans have a common ground, implementing all one special interface.

我想将所有的Bean创建转移到一个工厂.那将不得不提供这样的方法

I would like to move all that bean creation to one factory. That one would have to provide a methode like this

<T extends CommonInterface> T createInstance(Class<T> clazz);

我可以在其中实现创建我的一个特殊bean所需的所有实例化.

There I could implement all the instantiation necessary to create one of my special beans.

我的实现将在春季被调用

My implementation would be called by spring for

@Autowired
private MyCommonInterfaceImplementation impl;

以这种方式

createInstance(MyCommonInterfaceImplementation.class)

到目前为止，我查看的是BeanFactory和FactoryBean，两者似乎都不是我要搜索的.

So far I looked at BeanFactory and FactoryBean, both seem not to be I'm searching for.

有什么建议吗?
