Spring Boot属性注入

问题：属性多，则 @Value多

@Component
public class Dog{
        @Value("${dog.nam}")
	    private String nam;
        @Value("${dog.age}")
        private Integer age;
	}

@Component
@ConfigurationProperties("dog")//读取dog开头的配置，通过set方法注入
public class Dog{
	//属性
	//set get
}

@Configuration
public class BeanConfig{
    @Bean
    @ConfigurationProperties("pig")
    public Pig pig(){
        return new Pig();
    }
}
