运行环境：Spring Boot 2.5.0, IDEA 2020.3.2

异常详细信息：

Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'com.example.demo.config.MyConfigProperties' 
available: expected single matching bean but found 2: myConfigProperties,test-com.example.demo.config.MyConfigProperties

一开始是这样写的

@Configuration
@PropertySource("classpath:myConfig.properties")
@ConfigurationProperties(prefix = "test")
@Component
@Data
public class MyConfigProperties {
private String name;
private int age;
}

@SpringBootApplication
@EnableConfigurationProperties(MyConfigProperties.class)
public class DemoApplication {public static void main(String[] args) {SpringApplication.run(DemoApplication.class, args);
}}


@RestController
public class IndexController {
@Resource
private MyConfigProperties myConfig; @RequestMapping("/config")
String customConfig() {
String name = myConfig.getName();
return name + myConfig.getAge();
}
}
