哪个是Spring相当于CDI @Produces注释的？ [英] Which is the Spring equivalent for the CDI @Produces annotation?

问题描述

当我使用CDI时，我可以使用 @Produces 注释，以创建一个要调用的生成器方法，以选择实现接口的bean将由 @Inject 注释。

When I was working with CDI, I could use the @Produces annotation to create a producer method to be called to choose which bean that implemented an interface would be injected by the @Inject annotation .

现在我正在使用Spring，但是我没有找到任何类似的东西。当我使用 @Autowired @Produces 注释相同的结果>注释？

Now I am working with Spring, but I didn't find anything similar. What I need to use to achieve the same result I had with the @Produces annotation in CDI when I use the @Autowired annotation?

推荐答案

您正在寻找 @Bean ：

You're looking for @Bean:

@Bean是XML元素的方法级注释和直接模拟。注释支持大多数提供的属性，例如：init-method，destroy-method，autowiring，lazy-init，dependency-check，depend-on和scope。

@Bean is a method-level annotation and a direct analog of the XML element. The annotation supports most of the attributes offered by , such as: init-method, destroy-method, autowiring, lazy-init, dependency-check, depends-on and scope.

示例（取自上面的链接）：

Example (taken from link above):

@Configuration
public class AppConfig {
    //similar to @Produces CDI annotation
    @Bean
    public TransferService transferService() {
        return new TransferServiceImpl();
    }
}
