一、场景复现

application.yaml

spring:application:name: config-testprofiles:active: devconfig:config-01:name: zhansancode: 001config-02:name: lisicode: 002

 导入配置类

@Configuration
@Import(ImportConfig.class)
public class Config {@Bean@ConfigurationProperties(prefix = "config.config-a")public ConfigInfo oneConfig() {return new ConfigInfo();}@Beanpublic String oneName() {ConfigInfo configInfo = this.oneConfig();return configInfo.getName();}}

Import配置类

public class ImportConfig {@Bean@ConfigurationProperties(prefix = "config.config-b")public ConfigInfo twoConfig() {return new ConfigInfo();}@Beanpublic String twoName() {ConfigInfo configInfo = this.twoConfig();return configInfo.getName();}@Beanpublic String twoName1(@Qualifier("twoConfig") ConfigInfo configInfo) {return configInfo.getName();}
}

运行结果

oneName为zhansan

twoName为null

twoName为lisi

 

 

 二、分析原因

由于@Configuration标注的类代理，自动增强拦截功能。@Import的类没有被@Configuration修饰，所有没有增强方法注入
