spring 框架可以用基于 XML 的配置覆盖基于 Annotation 的配置吗? [英] Can spring framework override Annotation-based configuration with XML-based configuration?

问题描述

spring框架可以用基于XML的配置覆盖基于Annotation的配置吗?我需要更改已经通过注释定义的 bean 的依赖关系，并且我不是 bean 的作者.

Can spring framework override Annotation-based configuration with XML-based configuration? I need to change a dependency of a bean which is already defined via annotations and i am not the author of the bean.

推荐答案

应该没问题.Spring bean 上下文允许您重新定义 bean，较晚的"定义覆盖较早的".这应该适用于 XML 定义的 bean 以及注释定义的 bean，即使它们是混合的.

This should be OK. A Spring bean context allows you to redefine beans, with "later" definitions overriding "earlier ones". This should apply to XML-defined beans as well as annotation-defined beans, even if they're mixed.

例如，如果你有

@Configuration
public class MyAnnotatedConfig {
   @Bean 
   public Object beanA() {
      ...
   }
}

<小时>

<bean class="com.xyz.MyAnnotatedConfig"/>

<bean id="beanA" class="com.xyz.BeanA"/>

在这种情况下，beanA 的 XML 定义应该优先.

In this case, the XML definition of beanA should take precedence.
