如何通过配置spring xml来扩展spring [英] How to extend spring by configuring spring xml

问题描述

在Spring 4应用程序中，我们扩展了 PropertySourcesPlaceholderConfigurer 以在解析属性期间执行一些自定义任务.

In a Spring 4 application, we are extending PropertySourcesPlaceholderConfigurer to do some custom task during resolving properties.

要注册我们的新类(MyPropertyConfigurer)o Spring，请使用以下类:

To register our new class (MyPropertyConfigurer) o Spring we use the following class:

@Configuration
public class AppConfig {
  @Bean
    public static PropertySourcesPlaceholderConfigurer
    propertySourcesPlaceholderConfigurer() {
        return new MyPropertyConfigurer();
    }

}

出于好奇，我可以使用spring.xml而不是使用@Configuration注释将新bean添加到Spring吗?

As a matter of curiosity, can I add my new bean to Spring with spring.xml instead of using the @Configuration annotation?

推荐答案

我遇到了同样的问题，只需将类的bean放入我的Springbeans.xml文件中即可解决问题，如下所示:

I had the same problem, my problem was fixed simply with placing the bean of my class in my Springbeans.xml file like below:

<beans:bean class="MyPropertyConfigurer"/>
